The dynamics of structural and functional changes of the heart developing within three years in patients with ischemic heart disease after myocardial infarction is studied. Some peculiarities of the development of the remodulation process in postinfarctial period are revealed. The changes of the heart structure have a progressive nature. Early prescription of inhibitors of angiotensinconverting enzyme after myocardial infarction to prevent progress of the heart remodulation is advisable.

Objective. To conduct a comprehensive study of patients with ischemic heart disease (IHD) in combination with arterial hypertension (AH) complicated by chronic heart failure (HF) 2A and 2B, by studying parameters of intracardiac hemodynamics considering the pressure in the pulmonary artery.Research results. We examined 120 patients with coronary heart disease in combination with hypertension aged 44 to 90 years old (mean age 72.29 ± 1.66), the majority were men (86.7%). All patients were divided into two groups according to the degree of heart failure: HF 2A - 54 persons, with HF 2B - 66 people. The groups were compared in age, gender, functional class of IHD, severity of AH and HF.Analysis of heart ultrasound showed the following. In IHD in combination with hypertension, complicated by HF 2A, the pressure in the pulmonary artery rises in an average to 46.46 ± 3.64 mm Hg and it increases in HF 2B to 57.00 ± 5.19 mm Hg., that corresponding to the average level of pulmonary hypertension (p<0.01); at the same time, the fraction of ejection of left ventricle in the first patients decreases moderately up to 45.96 ± 2.01%, in others - to 39.93 ± 1.99% (p ˂0.01).In patients with IHD in combination with hypertension complicated by chronic heart failure the structural and functional changes are formed on the side of the left heart, accompanied by an increase in their size due to hypertrophy, formation of stagnant phenomena, regurgitation, functional state disorders by the restrictive type, progressive systolic and diastolic dysfunction, increased pressure in the pulmonary artery.Conclusions. Consideration of pulmonary hypertension, along with other parameters of intracardiac hemodynamics, is an important component in determining the degree and nature of heart failure, which requires the selection of adequate and timely therapeutic tactics.

Цель исследования: изучить изменения структурно-функционального состояния клеток крови у пациентов с ишемической болезнью сердца (ИБС) в различные сроки после экстренной рентгенэндоваскулярной реваскуляризации миокарда (РЭРМ) на фоне антиагрегантной и антикоагулянтной терапии Материалы и методы. Проведено исследование локальных механических и вязкостных свойств мембран эритроцитов методом атомно-силовой микроскопии и оценка степени агрегации эритроцитов у 32 пациентов с ИБС в период обострения заболевания, через 10 суток и 1, 3, 6, 8 и 12 месяцев после экстренной РЭРМ. Результаты. Показано, что при обострении течения ИБС модуль упругости эритроцитов был ниже, сила адгезии их мембран и степень агрегации красных клеток крови были выше, чем у практически здоровых лиц. Заключение. Стабилизация состояния пациентов сопровождается увеличением локального модуля упругости, уменьшением силы адгезии мембран и снижением степени агрегации эритроцитов. При стабильной стенокардии увеличение модуля упругости сопровождается повышением вязкости мембраны и снижением агрегационной способности эритроцитов. Aim: to study structural and functional changes of blood cells in patients with ischemic heart disease (IHD) at various periods after urgent roentgen-endovascular myocardial revascularization (REMR) under antiplatelet and anticoagulant therapy. Materials and methods. The study of local mechanical and viscous properties of erythrocytes’ membranes by atomic-force microscopy and estimation of erythrocytes’ aggregation degree in 32 patients with IHD at the acute period and in 10 days, 1, 3, 6, 8, and 12 months after urgent REMR was performed. Results. It was shown that at the period of IHD recurrence erythrocytes’ elasticity modulus was lower, adhesion strength of their membranes and degree of red blood cells’ aggregation were higher than in practically healthy persons. Conclusion. Stabilization of patients’ state is accompanied by increasing of the local elasticity modulus, reduction of membranes’ adhesion strength and degree of erythrocytes’ aggregation. At the stable angina increase of the elasticity modulus is accompanied by decreasing in both membrane’s viscosity and erythrocytes’ aggregability.
