FEATURES COURSE OF NEW CORONAVIRUS INFECTION COVID-19 AGAINST THE BACKGROUND OF CARDIOVASCULAR DISEASES
Purpose: study of the course of a new coronavirus infection COVID-19 in patients with cardiovascular diseases.Material and methods: the course of the new coronavirus infection COVID-19 was studied against the background of cardiovascular diseases in 308 patients hospitalized in the hospital of particularly dangerous infections № 1 in Nalchik with a verified diagnosis. The age of patients is from 45 to 70 years. At admission, all patients underwent a basic electrocardiography in 12 leads, according to the indications, an echocardiographic examination of the heart. The patients were divided into 2 groups: group 1 (n=182) consisted of patients with cardiovascular diseases, group 2 - patients (n=126) without cardiovascular diseases.Results and discussion: analysis of the structure of cardiovascular diseases in COVID-19 patients showed that the most common pathology was arterial hypertension, which was registered in 93.4% of COVID-19 patients, in 2 place chronic heart failure (60,9%), in 3 place cardiac arrhythmias (40,1%). Ischemic heart disease was observed in 21,9% of patients. The study of the structure and frequency of cardiac arrhythmias in dynamics showed an increase in the prevalence of supraventricular extrasystoles among COVID-19 patients (10,4% initially and 14,3% in dynamics), ventricular extrasystoles by more than 2 times.Conclusions: a more severe course of COVID-19 was observed in patients with cardiovascular diseases: complications andmortality rates were significantly higher compared to the group of patients without cardiovascular diseases.
