ABSTRACT
Purpose. To establish the factors influencing the progression of chronic coronary heart disease (CCHD) in patients with postinfarction cardiosclerosis after COVID-19 infection. Materials and methods. Included 45 patients with CCHD and postinfarction cardiosclerosis from among those who were under dynamic observation in the CCHD laboratory of the Republican Scientific and Practical Centre "Cardiology". All included in the study were divided into 2 groups: group I (31 patients) – after COVID-19, group II – patients with CCHD who did not have a COVID infection – 14. The I test was carried out in the pre-Covid period, the II test – within 1-3 months after documented COVID-19. Examination included echocardiography (EchoCG), computed tomographic angiography (CTA) of the coronary arteries (CA), magnetic resonance imaging. Results. Risk factors influenced on the progression of CCHD in patients after COVID-19 are: increased for more than 1 month levels of C-reactive protein (CRP), cardiac troponin, erythrocyte sedimentation rate (ESR), D-dimer. All mentioned factors contributed to the progression of coronary artery atherosclerosis. The coronavirus infection affected the enlargement of the left ventricle and the right parts of the heart, the deterioration of the systolic-diastolic function of both ventricles, including an increase in pressure in the pulmonary artery. The consequence of these changes was the progression of signs of heart failure according to echocardiography and the n-terminal fragment of the natriuretic peptide (NT-proBNP), an increase in the zones of myocardial ischemia compared with the pre-COVID period, and more frequent and significant ventricular arrhythmia. © 2022, Professionalnye Izdaniya.
