Factors of poor prognosis for new coronavirus infection in patients with cardiovacular pathology

Abstract

Aim. To assess the structure of cardiovascular pathology in patients with new coronavirus infection (NCI), to identify factors of poor prognosis in these individuals. Material and methods. The study was conducted on the basis of the COVID-19 infectious diseases hospital of the City Hospital No. 33 of Nizhny Novgorod. The study included 284 patients after applying inclusion and exclusion criteria. All subjects were divided into groups: the main group (n = 207) — patients with NCI and cardiovascular diseases (CVD), as well as comorbid diseases, the comparison group (n = 24) with NCI and CVD, the control group (n = 53) with NCI without any comorbid diseases. Demographic indicators, BMI, laboratory parameters, comorbidity and therapy were analyzed. Results. During the study, it was revealed that the most severe course of COVID-19 is characteristic of the main group, and only among them there were fatal outcomes (25% of cases). Analyzing the prevalence of CVD, it turned out that arterial hypertension was the most common in the main group and in the comparison group, coronary heart disease and heart failure were registered somewhat less frequently. The development of acute cardiovascular accidents occurred only in the main group. A mathematical model was developed to determine the risk of death in patients with NCI who are in the hospital. This model is statistically significant (p < 0.001). Conclusion. The older age of patients, the development of acute myocardial infarction, first identified atrial fibrillation and a decrease in saturation contributed to an increased risk of mortality in patients with NCI and CVD. Among drug therapy, the administration of favipiravir, tocilizumab and statins had a beneficial effect on the outcome of diseases.
