OPTIMIZATION OF SPECIFIC THERAPY FOR PULMONARY ARTERIAL HYPERTENSION: THE POSSIBILITIES OF USING ENDOTHELIN RECEPTOR ANTAGONISTS
Martynyuk T.V., Nakonechnikov S.N., Chazova I.Ye.

Modern concepts of pulmonary arterial hypertension (PAH)pathogenesis focus on the key role of endothelial dysfunction of pulmonary vessels.
To control the activation of endothelin-1 system, endothelin receptor antagonists (ERA) are ñurrently used. Until recently, this class of drugs in our country and abroad was represented by two drugs: the sulfonamide derivative – a nonselective ERA bosentan and a non-sulfonamide derivative – ambrisentan, which blocks only ETA-receptors. Not the selectivity of ERAs, but their pharmacokinetic characteristics determine the differences in the profile of efficacy and safety. In 2015, in our country there appeared a new dual antagonist macitentan, which was created to optimize the tissue effects by increasing lipophilicity. In randomized SERAPHIN study, the use of macitental 10 mg compared with placebo contributed to a reduction of the risk of morbidity and mortality in patients with PAH by 45%, and the effect of therapy was not dependent on whether the patients received concomitant specific therapy with inhibitors of phosphodiesterase type 5, oral or inhaled prostanoids.
In the paper there summarized indications for prescribing ERA, the data of the evidence base, as well as the concept of switching to optimize the ERA treatment. It is important to emphasize that in case of a satisfactory clinical response with ERA therapy, correction of therapy seems discrete. In the European guidelines 2015, this issue is not considered as having no extensive evidence base. On the other hand, it cannot be ruled out that the use of generic bosentan may lead to a decrease in the treatment effecacy and to provoke the clinical deterioration. At present clinical data intensively accumulate in favor of the strategy of switching from bosentan or ambrisentan to macitentan in PAH patients. It is necessary to assess the potential benefits associated with ERA switching to macitentan, in comparison with the possibilities of combination therapy.

APPLICATION OF NEW ECHOCARDIOGRAPHIC TECHNOLOGIES OF NON-DOPPLER MYOCARDIAL IMAGES IN 2D AND 3D MODES IN PATIENTS WITH CHRONIC HEART FAILURE WITH PRESERVED AND REDUCED EJECTION FRACTION
Sohibnazarova V.Kh., Saidova Ì.À., Tereshenko S.N.

According to the recommendations of the European Society of Cardiologists, transthoracic echocardiography (TTE) is the most informative diagnostic method in patients with chronic heart failure (CHF) [3]. Echocardiography provides accurate information on the size of heart chambers, wall thickness and indices of systolic and diastolic function. Nowadays, in view of the new technological development, the most perspective technologies for the integrated assessment of the functional condition of the myocardium of the left ventricle (LV) are the ones that assess not only the ejection fraction (EF), but also the deformation parameters and rotational properties of the LV myocardium, including technologies of non-Doppler myocardial images in 2D and 3D modes (2D and 3D Speckle Tracking Echocardiography or STE). Based on the 2D Speckle Tracking Echocardiography data, reduction of the global longitudinal deformation has more prognostic significance in risk of death assessment in patients with heart failure than the EF of LV and the index breach of the local contractility of LV. However, the method of evaluating myocardial deformation in 3D mode STE and its advantages over the 2D mode STE is insufficiently explored. Thus, for the assessment of LV systolic and diastolic dysfunctions in patients with CHF with preserved and reduced EF of LV, a great interest represents the application of the new echocardiographic technologies, such as the 2D and 3D Speckle Tracking Echocardiography.
Key words: chronic heart failure, strain of the left ventricle, rotational properties of the left ventricle, non-Doppler myocardial imaging.

CLINICAL CASE OF COMBINATION THERAPY INCLUDING AMBRIZENTAN IN THE PATIENT WITH SEVERE IDIOPATHIC PULMONARY ARTERIAL HYPERTENSION
Movsisyan G.A., Arkhipova O.A., Korobkova I.Z., Matchin Yu.G., Saidova M.A., Martynyuk T.V., Chazova I.Ye.

Idiopathic pulmonary hypertension (IPAH) is a rare cardiovascular disease of unknown etiology, but the most common form of pulmonary arterial hypertension, defined as mean pulmonary arterial pressure >25 mmHg and pulmonary vascular resistance >3 Wood Units. Endothelial dysfunction seems to play an integral role in the pathogenesis of IPAH: the activation of endothelin-1 causes the hypertrophy of smooth muscle cells and endothelial cells, fibrotic changes, immune inflammation and vasoconstriction which leads to small pulmonary arteries and arterioles remodeling. The endothelial system activation is the reason for using endothelin receptor antagonists (ERA) to block the endothelin receptors type A (ETA) or both types (ETA, ETB). ERA, as the main class of PAH-specific therapy, is presented by bosentan and macitentan, dual endothelin receptor antagonists, and ambrisentan, non-sulfonamide, ETA-selective ERA. This clinical case demonstrates the successful treatment with ambrisentan as the part of combination therapy in the patient with severe IPAH.

Stelmashok V.I., Polonetsky O.L., Strygo N.P., Zatsepin A.O., Mrochek A.G.

Aim. To define principles of coronary wire choice during coronary artery chronic total occlusion (CTO) recanalization by antegrade approach.
Material and methods. From 2009 to 2013 the attempt of coronary artery CTO recanalization by antegrade approach was undertaken for 217 patients. Depending on success of CTO crossing by coronary wire patients were divided into 2 groups: group 1 (n=164) – successful wire crossing, group 2 (n=53) – unsuccessful attempt of CTO recanalization by coronary wire.
Results. In the group 2 there were more frequent CTO localization in the right coronary artery (p<0,05 as compared to group 1), presence of blunt stump, higher frequency of side branches in the zone of proximal CTO cup, and large CTO length (p<0,001 as compared to group 1). CTO recanalization in 47% cases begun from soft wire with polymeric coating and tapered tip, successful recanalization by these wire type was achieved in 49,02% patients. Using non-tapered tip intermediate stiffness wire as the first choice wire was associated with the failure of recanalization (p=0,0440 in intergroup comparison). At impossibility of CTO recanalization by soft wire with polymeric coating and tapered tip used as a first choice, it replacement on non-tapered tip intermediate stiffness wire allowed to achieve successful recanalization in 36,67% patients. In the cases of this strategy uneffectiveness using stiff wire with polymeric coating and tapered tip as a third choice allowed additionally to attain successful recanalization in 60% cases. Replacement of the soft wire with polymeric coating and tapered tip on stiff wire with polymeric coating and tapered tip, executable at presence of meaningful rigidity in the proximal CTO cup zone associated with the achievement the successful recanalization in 60% cases.
Conclusion. On the basis of the obtained data it was created the conception of step-up wire stiffness increase during the CTO recanalization by antegrade approach.

Shek A.B., Kurbanov R.D., Abdullayeva G.J., Nagai A.V., Abdullaev A.A., Ahmedova S.S., Hoshimov S.U., Ziyaeva A.V.

Background. It is well-known that in majority of cases treatment with statins can be safe and well tolerated, but in some patients observed statin-induced adverse liver or muscle symptoms - the main reasons for statin discontinuation. Asian ethnicity – is one of the predisposing factors for statin-associated adverse effects.
Objective. To study possible effects of CYP3A5 (6986A>G), CYP2C9 (430C>T), CYP2C9 (1075A>C), SLCO1B1 (521T>C) and BCRP (ABCG2, 421C>A) genetic polymorphism on simvastatin tolerance and safety in ethnic Uzbek patients with Coronary Artery Disease (CAD).
Material and methods. The prospective case-control research included 100 patients with CAD. Group "case" were 50 patients who demonstrated statin-induced adverse liver effects (transaminase level increases 3 times and more – in 37 cases) or statin-induced elevations in serum CK (of >3×UNL – in 4 cases) at treatment with simvastatin with the dose of 20 mg/day for 3 months of treatment and 13 with myopathy, associated with increased levels of total creatine phosphokinase (CPK) 3 times or more. In 4 patients with adverse effects on the liver, along with an increase in the enzymes, while there was an increase of CPK levels. Control group contained 50 patient with CAD treated with simvastatin with the dose of 20-40 mg/day for one year without side effects. The both groups of patients were similar in gender, age, original index of kidney function and serum CK level. The comparison group consisted of healthy ethnic Uzbeks (n = 41) of comparable age and sex, with the absence of a family history of coronary artery disease. The research was performed by means of PCR-RFLP method.
Results. As a whole, all genotypes (except for CYP2C9 * 2 in patients) were in Hardy–Weinberg equilibrium. Among patients with simvastatin intolerance, compared to the control group, the following genotypes were observed more frequently with high level of confidence: CYP3A5 *3/*3, compared to genotype variants *1/*3 and *1/*1 (OR 9.33; 95% CI 3,37-25,9; P = 0.0001) and BCRP CA (patients with BCRP CC genotype were not observed among those examined) (OR 3.22; 95% CI 1,25-8,30, P = 0.024).
Conclusions. Genotypes CYP3A5 *3/*3 (6986A>G) and BCRP CA (ABCG2, 421C>A) are accompanied with the increase of statin-induced adverse effects in ethnic Uzbek patients with Coronary artery disease.
Key words: statin intolerance, polymorphisms of genes CYP3A5, CYP2C9, SLCO1B1, BCRP.

Martynyuk T.V., Dadacheva Z.H., Paramonov V.M., Saidova M.A., Nakonechnikov S.N., Chazova I.Ye.

Aim: to study the efficacy of sildenafil therapy in pulmonary hypertension of different etiology, its influence on the clinical, functional, hemodynamic status, structure and function of the right and left heart, right ventricular-arterial coupling (RVAC) in pts with idiopathic pulmonary hypertension (IPAH) and chronic thromboembolic pulmonary hypertension (CTEPH).
Materials and methods: in the study we included 29 IPAH pts aged 42.8±10.6 yrs, 28 CTEPH pts aged 43.4±10.4 yrs II-IV functional class (FC) (WHO), receiving stable standard therapy (anticoagulants, diuretics, glycosides) and calcium channel blockers for at least 3 months.
Sildenafil was started at the dose of 10 mg TID to assess the tolerability for further titration after 1 wk to 20 mg 3 times a day. The treatment duration was 16 wks. At baseline and at wk 16 FC (WHO), 6-minute walking test (6-MWT), transthoracic echocardiography (Echo) and right heart catheterization (RHC) were performed.
Results: both groups were comparable in baseline functional parameters: FC, the distance in 6-MWT, Borg index. The analysis of baseline structural and functional cardiac parameters by Echo in IPAH and CTEPH pts revealed pronounced cardiac remodeling as compared to the control group. All pts had criteria precapillary PH by RHC with comparable systolic pulmonary artery pressure (SPAP), mean pulmonary artery pressure (PAPm), cardiac output (CO) and index (CI), pulmonary vascular resistance (PVR) except for diastolic PAP (DPAP), which was higher in IPAH group (38.3±13.7 mm Hg vs 31.5±8.9 mm Hg in CTEPH group (p<0.05).
Sildenafil therapy resulted in the marked improvement of functional and hemodynamic status, cardiac remodeling parameters in both groups. To wk 16 IPAH pts achieved the 114m increase in 6-MWT as compared with 108m in CTEPH group. IPAH pts demonstrated the significant decrease in SPAP, PAPm, reduce of right ventricular (RV) size and improvement of contractile function - FAC and TAPSE, increase of RVAC by reducing LV stiffness. Eccentricity index of LV improved significantly only in CTEPH pts. Positive dynamic in RHC data (significant decrease of SPAP, PAPm, DPAP, PVR, increase of CO,CI, stroke volume). CTEPH pts showed a greater reduction in PVR, SPAP and significant SvO2 improvement.
Conclusion: 1. In pts with IPAH and CTEPH of comparable baseline clinical, functional and hemodynamic status we found no significant differences in the severity of cardiac remodeling, RV and LV systolic and diastolic function. Regardless of etiology RVAC was reduced due to the significant increase of LV stiffness- Es. 2. 16-wk sildenafil therapy in pts with IPAH and CTEPH resulted in the positive dynamic of 6-MWT distance, dyspnea index, Echo data including LV stiffness. 3. In CTEPH group as compared with IPAH pts we found the more marked reduction in PVR, PASP and significant improvement SvO2 by RHC. The significant decrease in Es was observed only in CTEPH pts.

THE MODERN VIEW OF THE ADDITIONAL THERAPY, CORRECTING METABOLIC PARAMETERS IN PATIENTS WITH PULMONARY HYPERTENSION: TRIMETAZIDINE IN FOCUS
Valeeva E.G., Martyniuk T.V., Ivanov K.P., Sergienko V.B., Nakonechnikov S.N., Chazova I.Ye.

According to the Russian data 34% of patients with pulmonary hypertension (PH) have complaints of chest pain. Currently, the cause of this symptoms can be as coronary heart disease, compression of the coronary arteries (usually the left main coronary artery) dilated pulmonary artery, coronary insufficiency due to low cardiac output is relatively weak development of coronary collaterals in the hypertrophy RV wall or a reflex constriction of the coronary arteries due to distension of the pulmonary artery, to the reduction of blood oxygen saturation in the late stages of the disease. Myocardial ischemia and chest pain reduce the quality of life of patients, and to be predictors of adverse outcomes. Therefore, treatment of these patients should be comprehensive and include PAH -specific and additional metabolic therapy. The therapy of the last group – trimetazidine – being actively researched in various pathologies, and shows the positive side in studies: the Cochrane meta-analysis of patients with ischemic heart disease. Trimetazidine has a pronounced anti-anginal efficacy and good tolerability in combination with other treatment, which will improve the quality of life of patients.

Gelis L.G., Medvedeva E.A, Russkich I. I., Lazareva I.V., Rusak T., Tamashevsky A.V.

Objective: to assess the impact of cell plasma hemostasis disorders and the level of biomarkers on clinical outcomes and to develop laboratory diagnostic criteria forecast recurrent coronary events in patients with unstable angina.
Material and Methods: the study included 124 patients with unstable angina. All patients were performed: complete blood count, to determine the level for TnI, the determination of inflammatory markers (hs C-reactive protein (CRP)), the level of myeloperoxidase, von Willebrand factor, the level of thrombin, fibrinogen (FG), antithrombin III (AT III), D-dimer, factor Xa), agregatogramm was performed an impedance aggregometer Multiplate and determining platelet activation by flow cytometry. All patients underwent ECG, echocardiogram, 24-hour ECG monitoring, coronary angiography.
Results: developed independent predictors of the risk of recurrent coronary events in patients with unstable angina: the threshold values for evaluating platelet aggregation analyzer Multiplate-ASPI-test (AUC) >52 U, ADP-test (AUC) >60 U; the peak concentration of thrombin ≥294,5 nM, platelet size – MPV >9,6 fl, myeloperoxidase level >316 pmol/l, hsCRP >3.8 g/l, and troponin I >0,07 ng/ml. We created the scale of the prediction of recurrent coronary events after suffering unstable angina.

Objective: the aim of our study was to determine the optimal instantaneous wave-free ratio (iFR) cut-off points in assessing the functional significance of intermediate coronary artery stenoses in patients with chronic coronary artery diseases (CAD) using non-invasive methods of myocardial ischemia verification as reference.
Methods: 60 patients with chronic CAD or suspected CAD and intermediate coronary stenoses (50-70%) were included in the study. 92 borderline coronary stenoses were investigated. iFR measurement was carried out within 10 days after the non-invasive stress test (a combination of stress echocardiography and SPECT).
Results: stress-induced myocardial ischemia was detected in 18 patients (30%). iFR values are in the range 0.68 to 1.0, median of iFR - 0.95 [0.9; 0.99]. Area under iFR ROC-curve – 0.95 ± 0.02 (95%CI: 0.885-0.985). The iFR cut-off point 0.92 is optimal and has a sensitivity of 100%, a specificity of 83% and a negative predictive value (NPV) of 100%. The iFR cut-off point 0.86 is associated with a specificity of 100%, a sensitivity of 33% and a positive predictive value of 100%. The values of iFR «grey» zone ranged from 0.87 to 0.92.
Conclusion: using non-invasive methods of verification of myocardial ischemia as a reference, iFR cut-off point 0.92 excludes the functional significance of coronary artery stenosis with a NPV of 100%. iFR cut-off point 0.86 confirms the functional significance of the stenosis with a PPV of 100%. It is recommended to measure the fractional flow reserve in the case of obtaining the iFR values of «grey» zone (0,87-0,92).

Ardashev A.V., Zotova I.V.

The main objective of the management of patients with atrial fibrillation (AF) is an effective prevention of ischemic stroke. For this purpose indirect and direct oral anticoagulants may be used. The choice of anticoagulant should be based on a comprehensive assessment of a number of factors – the presence of significant valvular disease, kidney function, potential drug interactions, risk of complications of anticoagulant therapy. Individual assessment of the profile of thromboembolic and hemorrhagic risks are largely determined by the age, can help choose an efficient anticoagulant with minimal risk of complications. In patients younger than 75 years, in the absence of contraindications to the use of direct oral anticoagulants, the drug of choice can be dabigatran, administered at a dose of 150 mg 2 b.i.d.

Azizov V., Rzayeva A., Agayeva K., Chatamzade E.,Mamedova S.

The prevalence of hypertension in the female population, depending on the presence of gestational hypertension history, set the sensitivity, specificity, and predictive value of gestational hypertension as a predictor of hypertension. The observation was carried out during the mandatory preventive examinations, the volume of which amounted to 643 women. The questionnaire for the study of obstetric history included a chronological description of all the pregnancies of more than 22 completed weeks of gestation. Inclusion in the object of study only workers of the railway system made it possible to clarify and supplement the personal information about gestational hypertension according to the history of the birth, which are stored in the archives of the railway hospital. Women aged 49-54 years with gestational hypertension often observed significant increase in blood pressure. Probability of high blood pressure in women aged 49-53 years, significantly increases depending on the number of pregnancies associated with gestational hypertension. Gestational hypertension is a highly sensitive (≥ 56,5%) and specific (≥46,0%) predictor of hypertension aged 49-53 years, the predictive value which is greater than 42.9%.

ATHEROMATOSIS OF ARTERIAL INTIMA AS A RESULT OF THE BIOLOGICAL FUNCTION OF ENDOECOLOGY, BIOLOGICAL REACTION OF INFLAMMATION AND UTILIZATION OF NON-LIGAND PALMITIC VERY LOW DENSITY→LOW DENSITY LIPOPROTEINS
Titov V.N., Shoybonov B.B.

Phylogenetically late intima of elastic arteries has no proteins for transportation of non-ligand oxidized low density lipoproteins (LDL) adsorbed on the matrix to resident macrophages. Phylogenetically early cells realize the reaction of extracellular digestion by secreting the proteolytic enzymes metalloproteases in the matrix. They hydrolyze matrix proteoglycans, adsorbed and non-ligand LDL, absorb detritis, and terminate hydrolysis of the most hydrophobic polyenic cholesterol esters (poly-CE) in lysosomes. Smooth muscle cells migrate from arterial media, change their phenotype from contractile to synthetic and produce in situ de novo matrix proteoglycans. Elastic arterial wall consists of three layers: a) endothelial monolayer, b) intima + media (smooth muscle cells) and b) adventitia. It seems reasonable to define functional differences between phylogenetically early resident macrophages and phylogenetically late monocytes→macrophages. They may be associated with scavenger receptors, CD36 translocase activity, production of acid hydrolases for poly-CE or realization of the biological reaction of extracellular digestion. We suppose that atheromatous masses are formed in the matrix of arterial intima but not in lysosomes when the ability of monocytes→macrophages to provide endocytosis of non-ligand LDL from the matrix is limited. If atheromatosis is a syndrome caused by intracellular deficiency of essential polyenic fatty acids (PFA), intimal atheromatosis is associated with partial utilization of excess PFA in the matrix of elastic arteria. At late stages of phylogenesis the intima formed from smooth muscle cells of the media.

Vaikhanskaya T.G., Sivitskaya L.N., Danilenko N.G., Kurushka T.V., Davydenko O.G.

This article presents the current view on the structure and functions of nuclear lamin proteins, pathological phenotypes of persons with LMNA mutations and clinical problems of lamin-related dilated cardiomyopathy diagnostics and management. Dilated cardiomyopathy (DCM) caused by mutations in the LMNA gene is often associated with conduction disorders, cardiac arrhythmias and extracardiac features with discrete muscle disruption. This disease is characterized by a poor prognosis and high risk of sudden cardiac death due to conduction disturbances (life-threatening blockade) or ventricular tachyarrhythmias (fatal ventricular tachycardias\fibrillation). We describe here 2 cases of lamin-type DCM associated with definite LMNA mutations. Educational focus for reader-cardiologist is à recognition of potential carriers followed by molecular genetic testing for diagnostics of LMNA mutation and tissues regarding optimal management of patients, especially timing for prophylactic cardioverter-defibrillator.

Objective: the main objective of our research work was an evaluation of clinical and hemodynamic profile, neurohormonal indicators in patients with IPH, depending on the results of vasoreactivity testing.
Methods: the study included 131 patients with IPH (mean age 32,4±3,2 years. All the patients underwent the routine laboratory tests, 6-minuts walking test (6-MWT), transthoracic echocardiography, thorax organs radiography, right heart catheterization (RHC) with acute pharmacological test (APT) using one or two vasodilators (VD) In order to study neurohumoral status the analysis of the 6-keto-PgF1b, NO, ET-1, norepinephrine, epinephrine levels, NT-proANP, NT-proBNP (NUP), renin activity, AII, aldosterone (RAAS) activity was conducted.
Results: significant differences of clinical and hemodynamic profile and neurohormonal indicators in patients with IPH depending on the availability (APT +) and absence (APT-) of the vasoreactivity reserve of pulmonary arteries (PA) were established. Among the APT- patients the number of patients belonging to FC III was significantly greater in comparison with APT+ patients. FC IV refered only to the APT- patients. Significantly more patients with APT+ belonged to FC I and II. The 6-MWT revealed that patients with IPH with intact vasodilation reserve overcame significantly longer distance. Doppler echocardiography showed that in APT- group a greater level of systolic pressure in the pulmonary artery (SPPA). When comparing the RHDC data all the hemodynamic parameters in the groups varied considerably, prognostically better data marked APT+ group. According to thorax organs radiography APT- group had significantly higher leel of KTI. Comparative evaluation of neurohumoral status, regardless of the outcome of the APT, showed a significant difference in the groups.
Conclusion: the group of responders in comparison with the APT- patients group indicated more safe clinical-hemodynamic and functional status, and neurohumoral rates in the responders group were closer to the outcome in the control group.
Keywords: idiopathic pulmonary hypertension, acute pharmacological testing, right heart catheterization, neurohormonal indicators.

Average daily cases of death from all reasons for winter and spring period (35,8±1,57) statistically significantly (Ð <;0,05) differed from average daily cases of death from all reasons for the summer-autumn period (31,3±1,49).
The average daily quantity of death cases owing to BCSD was maximum in spring, and is minimum in fall (respectively: 23,6± 1,2 and 19,8±0,4; Ð<0,05). It is obvious that the risk of mortality owing to BCSD is more in winter and spring period, especially in spring.
The final result: despite the fact that the climate of Baku city is relatively mild, increasing of death risks in the winter and spring seasons are common.

LIMITATIONS ON PRIMARY PERCUTANEOUS CORONARY INTERVENTION FOR ST-SEGMENT ELEVATION ACUTE MYOCARDIAL INFARCTION IN THE CLINICAL PRACTICE
Kashtalap V.V., Kochergina A.M., Makarov S.A., KHERASKOV V.Yu., Barbarash O.L.

Purpose: to assess the non-performance rate of primary PCI in STEMI patients and determine the factors influencing the choice of approach for the management of patients based on Kemerovo Cardiology Clinic’s experience in 2012.
Material and Methods: 492 patients aged 30 to 92 years, admitted to the MBHI "Kemerovo Cardiology Dispensary" (the Regional Vascular Center in 2012 with a diagnosis of ST-segment elevation myocardial infarction) were included in the single-center prospective registry study. The mean age of patients was 64.42 ± 10.86 years.
Results: over 20% of STEMI patients admitted to the Kemerovo Cardiology Dispensary did not undergo emergency coronary angiography (CAG). These patients were older, predominantly female (64%), commonly with repeated MI (44%) and with the presence of renal and myocardial dysfunction. The group of patients, who were not selected for CAG, had significant patient delay between onset of symptoms and hospital admission (9 hours from onset of symptoms to hospital admission in the group of patients who were selected to emergency CAG and 30 hours - in patients who were not selected for CAG).
Conclusion: according to the results of the study, we determined a group of patients (up to 20%), who did not receive high-tech medical services because of time delay and had less favorable outcomes after STEMI. Therefore, the development of algorithms is particularly important as they can reduce the time delay in the pre-hospital period, as well as active patient selection for coronary angiography during the in-hospital period.
Keywords: myocardial infarction, advanced age, primary percutaneous coronary intervention.

THE ALCOHOL CHOLESTEROL, ITS BIOLOGICAL ROLE DURING PHYLOGENESIS, MECHANISMS OF STEROL PRODUCTION BY STATINS, PHARMACOGENOMIC FACTORS AND DIAGNOSTIC VALIDIDTY OF LOW DENSITY LIPOPROTEIN CHOLESTEROL
Titov V.N.

Hypolipidemic activity of statins is realized by inhibition of the alcohol cholesterol (CL) local pool production in hepatocyte endoplasmic reticulum. Before secretion of very low density lipoproteins (VLDL) into hydrophilic medium of the blood, CL covers the total hydrophobic mass of triglycerides (TG). The smaller the CL content in the monolayer between the enzyme (lipase) and substrate (TG), the higher the parameters of hydrolysis of palmitic and oleic VLDL. Statins act as follows: à) block hepatocyte production and decrease plasma content of nonesterified CL; b) activate TG hydrolysis in palmitic and oleic VLDL, formation of ligand VLDL and their uptake by insulin-dependent cells via apoÅ/Â-100 endocytosis; c) activate TG hydrolysis in linolic and linolenic low density VLDL, formation of ligand low density lipoproteins (LDL) and their uptake by apoÂ-100 endocytosis; d) reduce blood content of equimolary esterified by the alcohol CL polyenic fatty acids, CL esters and CL-VLDL. Nonphysiological effect of impaired function of trophology (nutrition) on fatty acid (FA) metabolism in a population cannot be abolished by prescribing medicines. For lowering cardiovascular morbidity it is necessary to modify environmental factors, i.e., reduce dietary content of saturated FA (primarily of palmitic), trans-FA and palmitoleic FA to physiological levels and increase dietary content of unsaturated FA. Saturated FA block cellular uptake of unsaturated FA. Deficiency of unsaturated FA and excess of palmitic FA lead to the development of atherosclerosis.
Key words: cholesterol, statins, saturated fatty acids, polyenic fatty acids, palmitic acid.

ACCORDING TO THE RESULTS OF THE EUROPEAN CONGRESS OF CARDIOLOGY 2015: NEW VERSION OF GUIDELINES FOR DIAGNOSIS AND TREATMENT OF PULMONARY HYPERTENSION
Chazova I.Ye., Martynyuk T.V., Nakonechnikov S.N.

 

INNOVATION IN PHARMACEUTICAL TREATMENT OF PULMONARY ARTERIAL HYPERTENSION: STIMULATOR OF SOLUBLE GYANYLATE CYCLASE – RIOCIGUAT
Taran I.N., Martynyuk T.V., Nakonechnikov S.N., Chazova I.Ye.

Pulmonary arterial hypertension (PAH) is a rare disease, diagnosed at a late stage with low functional class III or IV (WHO). PAH leads to severe right heart failure and ultimately, death.
The modern researches aim at exploring the potential therapeutic targets, as at developing new drugs that can affect the previously set target. Impaired NO production plays an important role in PAH pathogenesis; this is determined by the powerful vasodilatory action, as well as anti-inflammatory, anti-proliferative, and antiaggregatory effects.
Riociguat is the first in a new class of soluble guanylatecyclase stimulators to have proved efficacy in phase II of clinical trials. In the randomized, double-blind, placebo-controlled phase III study PATENT-1 (Pulmonary Arterial Hypertension soluble Guanilatcyclase-Stimulator Trial) study, 443 patients with PAH symptoms were randomized to receive placebo of riociguat in a single dose of 2,5 mg (with a dose titration based on tolerability to 2,5 mg TID a day) or a dose of 1,5 mg (with a dose titration according to portability to 1,5 mg TID three times a day). The study included naïve patients treated with endothelin receptor antagonists or prostanoids (except for parenteral ones). To 12wk of riociguat treatment the mean distance in 6-MWT increased by an average of 30 m in the group treated with the maximum single dose of 2,5 mg TID, or decreased by an average of 6m in the placebo group (difference between groups, 36 m, 95% confidence interval 20–52 m, p p<0,001). Riociguat improved 6-MWT in patients not previously treated with PAH-specific therapy (38 m), and in patients, taking endothelin receptor antagonists or prostanoids (36 m). In riociguat groups compared with placebo a decrease in PVR and PAPm (p<0,01) was noted, as well as an increase in cardiac index (p<0,0001) , a reduction in NT-proBNP (p<0,0001) , FC (p=0,003) and in the Borg index (p=0,002), ), the time of development of clinical deterioration (p=0,005) prolonged as well. Riociguat therapy was also characterized by good tolerance. Efficacy of treatment was maintained during long-term observation of PATENT-2study. The mean value of 6-MWT changed to 51±74?ì one year after observation, functional class (WHO) was increased in 33% , the stabilization of functional class was observed in 61 % patients and deterioration in 6 % patients, compared with baseline of PATENT-1.
Key words: pulmonary arterial hypertension, nitric oxide, guanylatecyclase stimulators, riociguat, phosphodiesterase type 5 inhibitors.

Arkhipova O.A., Martynyuk T.V., Samoilenko L.E., Sergienko V.B., Chazova I.Ye.

The pulmonary hypertension is characterized by increase of pulmonary vascular resistance, pressure in a pulmonary artery, remodeling of heart and vessels and the lowest survival of patients. It agrees offered in 2009 the European society of cardiologists to algorithm a ventilation/perfusion scintigraphy takes the central place in differential diagnostics between various forms of a pulmonary hypertension. The scintigraphic picture is well studied at patients with the pulmonary hypertension which has developed owing to the transferred thromboembolism of branches of a pulmonary artery. The distributions of RFP given direct comparison and nature of changes of perfusion depending on a genesis of pulmonary hypertension and gravity of a disease in literature aren't presented. At the same time the knowledge of features of scintigrams can be useful in differential diagnostics and a forecast assessment at patients with a pulmonary hypertension of a various etiology.

Gaynitdinova V.V., Sharafutdunova L.À., Avdeev S.N.

Objective. Available data on the diagnostic value of determination of the concentration N-terminal pro-C-type natriuretic peptide (Nt-proCNP) to predict pulmonary hypertension (PH) in patients with COPD are few.
Aim. To determine the concentration of NT-proCNP in COPD patients and evaluate its diagnostic value for the prediction of PH in COPD.
Methods. The study involved 47 patients with COPD (GOLD II-IV, age 59,49±0,63 years, disease duration 13,7±0,63 years, smoking history 23,09±0,93 packs/years). NT-proCNP concentration in serum was assessed by ELISA technique (test Biomedica Medizinprodukte GmbH & Co KG, Austria). The pulmonary artery systolic pressure (SPAP) was analyzed by using a color-Doppler technique.
Results. Concentrations of NT-proCNP were significantly higher in COPD patients with PH (SPAP 40-55 mmHg, n=16) or severe PH (SPAP ≥55 mmHg, n=10) than in patients without PH (SPAP < 40 mmHg, n=21): 4.14±0.51 pg/ml, 5.26±0.21 pg/ml and 1.42±0.03 pg/ml (p<0.001), respectively. A significant correlation was found between the concentration of NT-proCNP and SPAP (r=0.53; p<0.05). The AUC for Nt-proCNP levels to predict PH and severe PH in COPD were 0.928 and 0.932, respectively.
Conclusion. The present study shows that the serum levels of NT-proCNP are significantly elevated in COPD patients with PH and can be used as a non-invasive specific biomarker for predicting PH in COPD.
Key words: chronic obstructive pulmonary disease, pulmonary hypertension, N-terminal pro-C-type natriuretic peptide (Nt-proCNP).

CLINICAL CASE OF SUCCESSFUL 10-YEAR AMBRIZENTAN TREATMENT OF THE PATIENT WITH IDIOPATHIC PULMONARY ARTERIAL HYPERTENSION
Martynyuk T.V., Saidova M.A., Danilov N.M., Lazutkina V.K., Chazova I.Ye.

Idiopathic pulmonary arterial hypertension (IPAH) is a rare cardiovascular disease of unknown etiology, characterized by pulmonary vascular resistance (PVR) and pulmonary artery pressure (PAP) increase due to pronounced remodeling of small pulmonary arteries and arterioles, with progressive deterioration and the rapid development of right ventricle failure. The key pathogenetic feature is the endothelial dysfunction, which leads to the development of vasoconstriction, thrombosis in situ, proliferative and inflammatory changes in the lung microvasculature.
Optimization of drug therapy is associated with the clinical implementation of highly effective pathogenetic drugs which act on the main disease targets - activation of endothelin-1 (ET-1) system, the lack of endogenous prostacyclin and nitric oxide. The role of ET-1 as a powerful vasoconstrictor that induces cell proliferation and differentiation, production of cytokines, growth factors, biologically active substances.
Endothelin receptor antagonists (ERA) represents the important class of PAH-specific therapy, including two non-selective ERAs- nonselective bosentan and selective ambrizentan. Presented clinical case demonstrates the long-term reliable efficacy and safety of ambrizentan for 10 years in the IPAH patient with the baseline functional class III (WHO).
Key words: idiopathic pulmonary hypertension, endothelin-1, endothelin receptor antagonists, ambrisentan.

Objective. To evaluate the prognostic significance Baevsky-index (BI), during the bicycle exercise test, in comparison with the data of coronary angiography (CAG) in patients with chronic ischemic heart disease.
Material and methods. The study involved 116 patients with chronic ischemic heart disease (men – 84.5%) of them with angina pectoris functional class 2 – 47 (40.5%), functional class 3 – 69 (59.5 %) patients. The average age of the subjects = 56,99±9,29 years. From the 116 surveyed 62 (53.4%) patients had a history of myocardial infarction.
More than 80% of the patients in the subsequent CAG were performed. Depending on the values of the BI patients were divided into 4 groups: 1gr. – 37 (31.9%) patients with BI <2.6; 2gr. – 31 (26.7%) patients with BI = 2.6-2.9; 3gr. – 40 (34.5%) of persons with BI = 3.0-3.5 and 4gr. – 8 (6.9%) patients with BI > 3.5.
Results. More than 85% of the patients were characterized by the presence of excess weight, and in 4gr. – 100% of patients. Also in 4gr. patients, lipid profile, in comparison with those in groups 1-3, were slightly lower and atherogenic index (AI) – was the smallest. Analysis of the echocardiographic parameters, in addition to the relative left ventricular dilatation, testified about reducing the contractile function of the heart muscle, and a more severe diastolic dysfunction in patients 4gr. According bicycle exercise tests, it was found that patients 4gr. characterized by the lowest level of maximal oxygen consumption (MOC 4gr. = 3,46 ± 0,94 MET, that is 22.9%, 16.6% and 12.6% was lower than in groups 1-3, respectively), and with the growth of values ??BI noted decline in the index of Duke. According to the CAG, the average score on the SYNTAX score reaches a maximum value in people 4gr. Correlation analysis found an inverse relationship between the BI and the index of Duke (p>0,05). At the same time, by comparing the value of BI and CAG data, in particular the amount of vascular lesions, direct correlation was observed (p<0.05).
Conclusion. Baevsky index has a direct correlation with the quantitative coronary lesion vessels and can be recommended as a predictor of more severe coronary lesions in patients with chronic ischemic heart disease in the outpatient practice.
Keywords: Baevsky index, bicycle stress test; Index of Duke; coronary angiography.

OUT-PATIENT METHODS OF REGISTRATION OF BLOOD PRESSURE IN CLINICAL PRACTICE
Kotovskaya Yu.V., Kobalava J.D.

In spite of the fact that clinical measurement of blood pressure which meets methodical requirements is still a basis for diagnostics of arterial hypertension and assessment of treatment efficiency, it is widely recognized that proper diagnostics and management of patients with arterial hypertension are impossible based only on the measurements of blood pressure which are carried out by doctor.
The out-patient methods of blood pressure monitoring – daily monitoring (ABPM) and measurement of blood pressure at home (home blood pressure monitoring (HBPM)) – enable to overcome restrictions of clinical measurement of blood pressure. The combined use of clinical and out-patient measurement of blood pressure significantly expands understanding of Blood Pressure phenotype at the stage of diagnostics and assessment of treatment efficiency, especially at discordance of their results. Only by means of these methods it is possible to detect white-coat hypertension and masked hypertension.
The existing out-patient methods of blood pressure monitoring, its description, comparison, advantages and disadvantages, its places in modern recommendations and clinical practice guidelines as requirements to technique are provided in this article.

Objective: to study the parameters of central aortic blood pressure and main arteries stiffness in patients with coronary artery disease (CAD) depending on the prevalence of atherosclerotic lesions.
Material and methods. The study involved 90 patients with a diagnosis of unstable angina class II B (E. Braunwald et al., 1989) the control group consisted of 27 healthy people. The method of applanation tonometry using the apparatus of SphygmoCor («AtCor Medical», Australia) studied the performance stiffness: pulse wave velocity (PWV) and augmentation index (AIx). Coronary angiography was performed at the facility Allura CV-20 (Philips, The Netherlands), the state of the carotid arteries was studied by duplex ultrasonography, evaluation of involvement of femoral arteries was based on ankle-brachial index <0.9, in case of doubt, underwent ultrasound duplex scanning. In the main group, patients were divided into 3 subgroups: subgroup A defined patients with isolated coronary lesion; subgroup B was presented by patients who diagnosed combined lesion: coronary arteries with carotid arteries or coronary arteries with femoral arteries; subgroup C was presented with multifocal atherosclerosis patients who had atherosclerosis lesion in three vascular beds: the carotid, coronary and femoral arteries.
Results. Values PWV (11,2±1,5 m/s), and AIx (19,8±5,0%) in patients with CAD were, respectively, 1.5 (p<0.001) and 2.4 (p<0.001) times higher than in healthy persons. During the intra-group analysis in all three subgroups PWV was accelerated, with maximum values in the subgroup C (13,3±1,5 m/s), which significantly exceeds the value of this index in the subgroup A (10,1±0,6, p<0.01) and B (11,0±0,9, p<0.05). The value of augmentation index AIx was also highest in the subgroup C 26,8±6,4%, relative to the subgroup A (13,7±2,9%, p<0.001) and subgroup B (18,9±4,3%, p<0, 01).
Conclusion. The obtained results allow to recommend studied parameters of vascular stiffness as surrogate markers to assess the prevalence and progression of atherosclerosis, as well as efficacy of pharmacological interventions.

INVERSION OF THE CONCEPT ABOUT BIOLOGICAL ROLE OF RENIN→ ANGIOTENSIN-II→ ALDOSTERONE SYSTEM AND FUNCTION OF ARTERIAL BLOOD PRESSURE AS A METABOLISM REGULATOR
Titov V.N.

The phylogenetic theory of general pathology postulates an inversion of the concept about the role of arterial blood pressure (AP) in physiology and pathology. Activation of the synthesis of the renin→angiotensin-II (AG-II) system components by nephron and increase in aldosterone secretion are not aimed at elevating AP, but at maintaining the volume of extracellular medium, part of the Third Word Ocean where all cells still live as millions of years ago. Phylogenetically early internal organs cannot regulate the effects of phylogenetically late AP, a physical factor of metabolism. AP is not increased by kidneys, but by the vasomotor center that attempts to reanimate nephronal function, the biological function of endoecology and biological reaction of excretion by increasing AP in proximal and, subsequently, hydrodynamic pressure in the distal region of arterial bed. In addition to the major role in the realization of the biological function of locomotion, AP is a physical factor involved in compensation of impaired functions of homeostasis, trophology, endoecology and adaptation. Levels of metabolism regulation have developed during phylogenesis. Biochemical reactions are specifically regulated at the autocrine level. In paracrine-regulated cell communities of distal arterial bed, metabolism is regulated by millions of local peristaltic pumps by compensating the biological reactions of endothelium-dependent vasodilation, microcirculation, effects of humoral messengers and hormones. In vivo metabolism is regulated nonspecifically from the vasomotor center level by a physical factor (AP) by sympathetic activation of the heart; AP in proximal and distal regions of arterial bed overcomes peripheral resistance and «squeezes through» the arterioles where microcirculation is impaired. AG-II acts as a vasoconstrictor only in the distal arterial bed. In essential (metabolic) arterial hypertension, paracrine cell communities of nephrons and kidneys are involved in realization of pathologic compensation in the second turn and often “suffer being innocent” , similar to other “target” organs”, such as brain, lungs and heart.

Martynyuk T.V., Dadacheva Z.H., Paramonov V.M., Arkhipova O.A., Nakonechnikov S.N., Chazova I.Ye.

The key component of the pathogenesis of pulmonary hypertension (PH) is endothelial dysfunction with imbalance between vasodilators and vasoconstrictors and activation of the blood coagulation system. Randomized trials showed a beneficial effect of phosphodiesterase type 5 (PDE-5) inhibitors on vascular remodelling and vasodilatation in pulmonary arterial hypertension (PAH). Sildenafil is the only PDE-5 inhibitor that is officially approved by Pharmacological Commitee in our country. PDE-5 inhibitors by blocking the breakdown of cyclic guanosinemonophosphate (cGMP) resulted in prolongation of the action of vasoactive mediators including nitric oxide (NO) that cause vasodilation and antiproliferation in the lung. Sildenafil demonstrated the efficacy in uncontrolled clinical studies in pts with idiopathic pulmonary hypertension, PAH due to systemic connective tissue disease, congenital heart defects, with pulmonary embolism. 25-75mg at doses 2-3 times a day in patients with improved pulmonary hemodynamics, exercise tolerance. Basis for the authorization of this drug in the setting of PAH was a large randomized, placebo-controlled trial in which different doses of sildenafil were assessed in 278 patients presenting with idiopathic PAH, PAH related to connective tissue disease or congenital systemic to pulmonary shunts surgically corrected. After three months of treatment significant hemodynamic and functional class improvements were noted in every sildenafil group as compared to placebo. An approved dose is 20 mg three times a day, but in clinical practice often higher doses of 40-80 mg to 3 times per day are in need. Stable long-term efficacy of Sildenafil was observed with the dose of 80 mg 3 times a day in SUPER-2 trial. PACES trial demonstrated the efficacy of sildenafil in combination with intravenous epoprostenol.

INFLUENCE OF THE FACTOR FAMILY HISTORY ON THE RISK OF CORONARY HEART DISEASE
Behbudova J.A.

For the purpose of investigating the correlation between incidence of myocardial infarction (MI) and family history of cardiovascular disease (CVD), the study of prevalence of CVD among the first-degree relatives of patients with a known MI episode has been conducted. Medico-genetic files of two groups of patients with evidence of MI on ECG at rest have been analyzed: first group comprising patients who had an episode of MI before 55 years of age and second group comprising patients who had an episode after 55 years of age. A fairly high percentage of CVD in families of majority of patients with a known episode of MI has been noticed. However, this study has demonstrated a relatively low prevalence of coronary artery disease (CAD) and MI, including MI episodes before the age of 55, among fathers of patients from both groups. Moreover, occurrence of CAD and MI in fathers of the subgroup of patients who suffered from MI before 50 years of age of these patients practically showed no difference from that of subgroups of patients with episodes of MI at an older age. A fairly large amount of patients in both groups had no history of CAD in their families (41,5% and 41,2%, respectively). Considering the results mentioned above, there is no evidence to suggest that a predisposition of patients to MI episode at a younger age increases with existence of this disease in fathers of such patients. Results of our study suggest that increased presence of CVD and risk factors in first-degree relatives increases the probability of MI CAD in most patients of both groups regardless of the age of development of an MI episode.

A.A. Zenkov

Objectives. To estimate immediate and long term results of the minimally invasive coronary surgery (MICS) at the multiple lesions of the coronary arteries depending on completeness of the achieved myocardium revascularization for optimization of the surgical treatment of the patients with coronary heart disease (CHD). Materials and methods. From 2011 up to 2013 at the cardiac surgery department of ME “Vitebsk regional clinical hospital” 151 patients with the CHD underwent minimally invasive myocardium revascularization (MIMR) at the multiple lesions of coronary arteries. MIMR strategy was directed to avoid artificial cardiopulmonary bypass with cardioplegia and manipulations on the ascending aorta, usage of the left minithoracotomy access and tendency to perform complete or functionally reasonable arterial myocardium revascularization. 84 patients underwent complete MIMR, 67 patients - functionally reasonable incomplete MIMR. Results. Immediate results of the MIMR were found satisfactory (complete angina retrogression and absence of the major cardiovascular complications) in 99,3% patients and were compared in groups of patients who underwent complete (98,8%) or functionally reasonable (100%) MIMR (ð>0,05). Operation time was longer and emergency conversion to the assist extracorporeal circulation (AECC) was more frequent in the complete MIMR group of patients in comparison with functionally reasonable MIMR group (ð0,05). There were no major differences in the frequency of the recrudescent angina and major cardiovascular complications (combined adverse patient outcome) between complete and functionally reasonable MIMR groups of patients during long-term follow-up - 2,41% and 5,97% respectively (ð>0,05). Conclusion: MICS with aortic no-touch technique can be applied for majority of multivessel CHD patients as a complete, functionally reasonable or hybrid revascularization with or without AECC, saving the effectiveness and clinical effect duration of the coronary procedures.

This research was aimed to study the possibilities of multislice computed (MSCT) tomography to diagnose status of coronary arteries at the patients with ischemic heart diseases. Material and methods. The research includes the results of complex study of 70 patients, which were send to the cardiology department for the verification of ischemic heart disease, as well as for examination and correction of provided therapy at this category. All patients had been provided traditional invasive coronary angiography and MSCT of coronary arteries. Results. At the 29 (76,3%) patients of 1 group stenosis of coronary arteries were not revealed, in 6 (15,8%) patients were revealed insignificant hemodynamic stenosis. In 3 (7,9%) patients revealed significant hemodynamic stenosis and in 1 (2,6%) critical stenosis (narrowing coronary artery lumen ÊÀ > 90 %). By data of MSCT and coronary angiography was revealed strong correlative relationship in diagnosis of stenosis. These factors argue about high comparability of both methods. The greatest correlation relationship was revealed for trunk of left coronary artery, right descending artery and circumflex artery and was 9,2; 0,84 and 0,81 accordingly. Analogical indexes were less for the right coronary artery and was 0,71. Though, large part of the patients in main group was not needed in intracoronary intervention and surgical revascularization. Conclusion. MSCT can use as noninvasive alternative method of coronary angiography in patients with high risk of ischemic heart disease. Comparative analysis of MSCT of coronary arteries and invasive coronary angiography revealed that MSCT has sensitivity of 91%, specificity of 89%.

GLOMERULAR FILTRATION RATE AS A MARKER OF KIDNEY DAMAGE IN PATIENTS WITH ARTERIAL HYPERTENSION
Zelveian P.H., Dheryan L.G.

In the recent years there is a tendency for progressive increase in the number of patients with chronic kidney failure (CKF) in the world and, importantly, that this growth does not tend to slow down in the future. Numerous studies have proven a clear relationship between the degree and duration of arterial hypertension (AH) and incidence of CKF. In this view during AH glomerular filtration rate (GFR) reflects early, intermediate and also late stages of kidney damage and in this case changes of GFR have diverse character. So, an increase of absolute values of GFR is typical for early stages of AH and a decrease of GFR is typical for the late stages of AH. In the same time during AH GFR can be presented as a predicting risk factor for other target organ damage and cardiovascular morbidity and mortality development as well. Thus the evaluation of GFR should be more widely introduced in the clinical practice with the purpose of revelation of other cardiovascular risk factors and associated pathological conditions, continuous monitoring and prevention of target organ damage.
Key words: arterial hypertension, chronic kidney failure, glomerular filtration rate.

The aim. Studying of influence of the control glycaemia on development of diastolic dysfunction and remodelling of left ventricular in patients with type 2 diabetes mellitus (DM) with presence or absence of essential arterial hypertension was evaluated. Material and methods. In 133 patients with DM aged 26 to 66 years without ischemic heart disease the echocardiography with estimation of diastolic properties and diagnostics of remodeling of left ventricular has been investigated. Results. The diastolic dysfunction in 25.9% and remodeling of left ventricular in 35.4% patients with DM without essential arterial hypertension were observed. Poor compensation of DM (level of HbAlc >7,5 %), which was accompanied by more often development of demyelinating neuropathy, resulted in weighting of diastolic dysfunction and remodelling of left ventricular as with presence, and absence of the essential arterial hypertension in patients with diabetes. Conclusion. Absence of indemnification of exchange of the carbohydrates in patients with MD irrespective of presence of arterial hypertension associates with more expressed remodelling of the hearts.
Key words: type 2 diabetes mellitus, diabetic cardiomyopathy, arterial hypertension.

MECHANISMS OF PARASYMPATHETIC INFLUENCES ON THE HEART IN THE DEVELOPMENT OF OF THE EFFECT ANTIISCHEMIC DISTANT CONDITIONING MYOCARDIUM
Mrochek A.G., Bulgak A.G., Basalay M.V., Barsukevich V.C., Gurin A.V.

The aim of the study: to investigate the involvement of distinct parasympathetic and sympathetic beta-adrenergic mechanisms in infarct-limiting effect of remote ischemic conditioning. Materials and methods. Experiments have been conducted on white male rats. Remote ischemic conditioning was performed as 15-min bilateral femoral arteries occlusion before the onset of myocardial ischemia (RIPC, n=8), on the 10-th minute of ischemia (RIPerC, n=8) or on the 10-th minute of reperfusion (RIPostC10', n=8). To study the role of vagal nerves in the development of remote ischemic conditioning femoral arteries occlusion was performed in conditions of bilateral vagotomy (Vagotomy+RIPC, n=8; Vagotomy+RIPerC, n=7; Vagotomy+RIPostC10', n=8). M-cholinoreceptors were blocked by atropine (groups Atropine+RIPC, n=10; and Atropine+RIPostC10', n=6). Beta-adrenoreceptors blockade was induced by injection of metoprolol or atenolol on the 1-st minute of reperfusion to animals with intact vagal nerves (groups MetR+RIPostC10', n=10; and AtenR+RIPostC10', n=10) or after bilateral vagotomy (groups Vagotomy+MetR+RIPostC10', n=10; Vagotomy+AtenR+RIPostC10', n=10). Results. RIPC, RIPerC è RIPostC10' limited infarct size by 56%, 58% and 49% respectively (all p Ì-cholynoreceptors stimulation is a key point in the development of both RIPC, as well as RIPostC10'.
Key words: remote ischaemic heart conditioning, parasympathetic heart innervation, myocardial ischaemia and reperfusion.

Kurbanov R.D., Zakirov N.U., Irisov D.B., Khusanov Sh.S.

The aim of the study. Comparative analysis of the risk assessment of thromboembolism by CHADS2 and CHA2DS2- VASc scores, and to study the preventive effectiveness of different antithrombotic agents in patients with long-lasting àtrial fibrillation (AF) at 1 year follow-up. Materials and methods. The study included 108 patients aged 38 to 78 years old (mean age 62,6±8,4 years) with persistent or permanent AF. In 93.5% of patients revealed coronary artery disease and / or arterial hypertension, in 6.5% – non-coronary heart diseases. The risk of tromboembolism assessed by CHADS2 and CHA2DS2-VASc scores. Results. Patients at low risk of tromboembolism, according to CHADS2 score was 2.8%, in their absence, on a CHA2DS2- VASc score. Patients with moderate risk of tromboembolism, in these scores were 63.9% and 7,4% (χ2=72.653; p=0.000) respectively, and a high risk of tromboembolism – 33,3% and 92,6% (χ2=78,796, p=0.000) respectively. Depending on the ways to prevent tromboembolism, patients were divided into 2 groups. 1st group included patients treated with warfarin (n=90), and the endpoints were observed in 5.6% of patients. 2nd group included patients (n=18) treated with acetylsalicylic acid (ASA) and the end point was observed in 27.8% of patients. Conclusion. The introduction of a new CHA2DS2-VASc score led to an increase number of patients, who need mandatory anticoagulant therapy by 2.8 times. In the group of patients with atrial fibrillation treated with warfarin compared with a group of patients treated with aspirin, where cases of ischemic stroke have developed less often, and their clinical manifestation are less pronounced and are characterized by a benign course.
Keywords: atrial fibrillation, thromboembolism, CHADS2, CHA2DS2-VASc warfarin, acetylsalicylic acid.

 

AMBRISENTAN: THE POSSIBILITY OF THE TREATMENT FOR PULMONARY ARTERIAL HYPERTENSION WITH THE SELECTIVE BLOCKADE OF THE ENDOTHELIN SYSTEM
Martynuk T.V., Nakonechnikov S.N., Chazova I. E.

The optimization of the drug therapy for pulmonary arterial hypertension (PAH) associated with the introduction into clinical practice of highly effective drugs of pathogenetic action affecting the main targets of disease - activating the endothelin (ET-1) system, deficiency of endogenous prostacyclin and nitric oxide. The role of ET-1 in the pathogenesis of PAH due to powerful vasoconstrictive action, the ability to induce cell proliferation and differentiation, production of growth factors, cytokines, biologically active substances. Endothelin receptor antagonists (ERAs) – is the most important class of PAH- specific therapies, including two drugs – nonselective ERA bosentan and selective ERA – ambrisentan. The evidence base related to the application ambrisentan in PAH includes three key studies: testing of different dose regimes of the drug; 2 randomized, placebo-controlled, double-blind clinical studies and the study with replacement of ERAs on ambrisentan in patients intolerant other ERAs. In the study on ambrisentan dosage regimes testing increase of the distance in 6 - minute walk distance (6-MWT) was dosedependent. Using the drug in doses ranging from 1mg to 10 mg to 12 wks. there achieved a significant increase in 6-MWT distance of 33.9 m with 1mg dose (p=0.003) to 38.1m with 5mg (p=0.001). In two 12wk randomized, placebo-controlled studies ARIES- 1 and ARIES- 2 (Ambrisentan in PAH-a phase III, Randomized, Double-blind, placebo-controlled, multicenter, Efficacy Study of ambrisentan on Subjects with pulmonary arterial hypertension) the treatment with ambrisentan resulted to the significant increase of exercise tolerance according to 6-MWT from 22 m to 59 m when using the dose of 2.5mg (p = 0.022) and 10mg (p < 0.001), respectively. Ambrisentan treatment helped to reduce the need for lung transplantation, atrial septostomy, hospitalization for PAH progression. Achieved improvement was maintained for 2-year treatment with ambrisentan. Ambrisentan therapy was well tolerated. By 12 weeks the frequency of transaminases and bilirubin elevations was significantly lower with ambrisentan than for placebo group (0.8% versus 2.3%, respectively). Long-term follow up in the open study in 383 patients treated with ambrisentan, 95% of patients were alive at 1 year and 94 % of patients continued the treatment. Patients with adverse events when receiving bosentan or sitaksentan after translation to ambrisentan had no increase of liver transaminases. Thus, treatment with ambrisentan in PAH pts. resulted in the improvement of clinical symptoms and hemodynamic parameters, the increase in exercise tolerance and the prolongation of the time to the development of clinical deterioration. Favorable effects of long-term therapy with ambrisentan are shown for at least 2 years. In 2012 ambrisentan was approved by the Russian National Pharmacological Committee for the treatment of patients with PAH (Functional Classes II-III) at the dose of 5 mg and 10 mg PO.
Keywords: pulmonary arterial hypertension, endothelin-1, endothelin receptor antagonists, ambrisentan.

 

VALUE OF VOLUME FRACTION OF COLLAGEN IN DEVELOPMENT OF MYOCARDIUM REMODELING ATTHE PATIENTS WITH INFLAMMATORY CARDIOMYOPATHY
Ahmedova D.M., Hojakuliyev B.G.

Objective. Studying of a possible role of interstitial fibrosis in remodeling of myocardium. Material and methods. For the purpose of estimation of fibrosis, depending on degree of dilatation of the left ventricle there has been carried out examination of 42 patients with inflammatory cardiomyopathy, (middle age 35,01±1,0). Patients have been divided into 2 groups. The first group was made of 23 patients with EDS 5,8 cm. To all patients has been carried out ECG and EchoCG research. Results. At the patients of the 1st group CFV has made – 9,1±2,2%, while in the 2nd group – 13,3±2,4%. By comparison of two groups of the patients substantial growth of collagen fraction volume at the patients with expressed dilatation of cavities of the left ventricles and its prevalence at the patients with heavy ÑI is revealed more. At the patients with inflammatory cardiomyopathy thus the average index of distribution of collagen faction volume has made 11,1±3,1 % with fluctuations from 6 to 16 %. It is necessary to notice that in process of increase of signs of cardiac insufficiency CFV increases. So, at the patients with I-II CI FC CFV has made 9,8±3,0 % (CI 7,9-11,6), and at III - IV CI FC this indicator has increased already to 12,7±2,5 % (CI 11,0-14,4). The data obtained by us testifies that myocardium fibrosis at the patients with expressed cardiac insufficiency with dilatation of LV cavities much more, than at the patients with moderated ÑÍ. Conclusion. Thus, correlation between IMMLV and LVBW, which specifies dependence of structural changes on degree of fibrosis, and also the factors, promoting development of fibrosis at the patients with inflammatory cardiomyopathy is revealed.
Keywords: inflammatory cardiomyopathy, myocardium remodeling, collagen fraction volume, cardiac insufficiency.

 

MEDICAL TREATMENT OF CHRONIC THROMBOEMBOLIC PULMONARY HYPERTENSION
Mershin K.V., Martynuk T.V.

CTEPH is the only type of surgically curable pulmonary arterial hypertension. In spite that, up to 50% of all CTEPH patients are rejected of surgical treatment because of distal lesions of pulmonary arteries or because of other contraindications. Medical treatment was proven to be one of the options to support this cohort of patients. Recent clinical studies addressed some medication regimens for treatment of CTEPH patients and showed distinct changes of different PH-variables with time. We discuss the main principles of drug therapy for inoperable CTEPH as well as for patients awaiting surgery, during and after pulmonary thromboendarterectomy.
Key words: CTEPH, chronic thromboembolic pulmonary hypertension, PH-specific therapy, pulmonary thromboendarterectomy, PEA.
