Аннотация. Коморбидные заболевания у пациентов в условиях пандемии COVID-19 повышают риск неблагоприятного исхода за счет потенцирования системного повреждающего действия вирусного агента, возникновения «цитокинового шторма», декомпенсации хронической терапевтической патологии, развития острых осложнений, возможных лекарственных взаимодействий. Ведение данной категории пациентов требует знания особенностей вирусной инфекции, ее клинических проявлений при сочетании с коморбидными заболеваниями, а также мер индивидуальной и коллективной защиты.

The aim of the study was to investigate the features of clinically suspected myocarditis complicated by the left ventricular systolic dysfunction development. 93 patients with clinically suspected myocarditis were examined. The average age was 36.63 ± 1.15 years. In 43.01 % of patients the disease was accompanied by a decrease in left ventricular systolic function. In the group of patients with left ventricular systolic dysfunction in comparison with those with preserved left ventricular ejection fraction, a significantly lower proportion of men (75 % versus 81 %, respectively, χ2 = 9.3, p < 0,01) and a higher average group age (40.7 ± 1.87 versus 33.6 ± 1.3 years, respectively, p <  0,01) were revealed. The course of the disease in patients with left ventricular systolic dysfunction was characterized by a more frequent development of rhythm disturbances (65 % versus 43.3 %, respectively, χ2  = 4.3, p  < 0,05) and a higher heart rate at admission (94.5 (75‒100) and 85 (70‒89) beats per minute, respectively, p = 0.006). The structural and functional state of the heart according to echocardiography in patients with a reduced left ventricular ejection fraction versus comparison group was characterized by larger heart chambers sizes, more pronounced violations of local left ventricular contractility, more frequent involvement of the right ventricle in the pathological process (56.3  % versus 22.2  %, respectively, χ2   =  6.4, p  < 0,05).

C. 452–460 453 and the patient’s age (r = ‒0.36), the value of the heart rate at admission (r = ‒0.32), the severity of heart failure at admission, the degree of impaired local contractility of the left ventricle, the degree of right ventricular function (TAPSE, r  =  0.58), the severity of myocardial fibrosis according to cardiovascular magnetic resonance imaging (r = ‒0.32) were revealed.

The article provides data from epidemiological studies on the correlation between hypertensive disorders in pregnant women and the risk of cardiovascular diseases in later life, describes possible pathophysiological determinants for the occurrence of arterial hypertension after complicated pregnancy. The most informative predictors of the development of arterial hypertension in women with abdominal obesity are described, which were indicators of waist circumference, uterine artery resistance index, N-terminal fragment of the brain natriuretic peptide and highly sensitive C-reactive protein; a mathematical model was calculated to predict the probability of developing arterial hypertension in women with abdominal obesity and hypertensive disorders of pregnancy one year after delivery.

Chronic heart failure (CHF) is an important problem for the country, which has both medical and socio-economic aspects. The presence of the syndrome not only significantly increases the risks of an unfavorable course of diseases underlying its etiological basis, but in itself, through the development of decompensation, causes a high frequency of deaths. Despite all the advances in pharmacotherapy, the prognosis of heart failure remains poor. More than 40% of patients die within 4 years after the diagnosis of heart failure, and the one-year mortality rate for patients with severe CHF (NYHA class IV) exceeds 50%. The foregoing determines the need and importance of using all possible drug and non-drug therapy technologies aimed at reducing mortality, increasing the duration and quality of life of patients with CHF, as well as reducing the number and likelihood of decompensation and related hospitalizations, and makes this direction one of the priorities in medicine. The article describes current approaches to the treatment of patients with CHF syndrome from the perspective of evidence-based medicine and taking into account the recommendations of leading international organizations for the treatment and prevention of cardiovascular diseases. The drugs used were analyzed in terms of their influence on clinical symptoms, quality of life of patients, the risk of hospitalization due to decompensation of CHF, and mortality rates. The emphasis is made on the possibilities, mechanism of action and further prospects for the use of a new class of drugs in the treatment of CHF, acting at the level of the renin-angiotensin-aldosterone system and the system of neutral endopeptidases - inhibitors of angiotensin-neprilisin receptors.
