COVID-19 impact on hospitalization outcomes of patients with circulatory system diseases

Abstract

Background: The study is devoted to the impact of a new coronavirus infection in combination with other diseases on the hospitalization outcomes. Features of mortality in the population during COVID-19 pandemic, including from blood circulatory system diseases, have been studied. However, there are few studies based on the large amount of data on the cases and outcomes of providing specialized hightech medical care to patients with cardiovascular diseases (CVD) and concomitant diagnosis of COVID-19.Objective: The analysis of impact of a new coronavirus infection on the outcomes of hospitalization for circulatory system diseases.Material and methods: Information about more than 350 thousand cases of hospitalization of patients with blood circulatory system diseases in the context of the COVID-19 pandemic has been analyzed, of which in 1875 cases a concomitant diagnosis of COVID-19 was established. The sources of information are the depersonalized registers of compulsory health insurance accounts. For assessment of the obtained data methods of descriptive statistics, simple (unweighted) arithmetic mean values, mean values, specific weights of indicator values, a mean square (standard) deviation from mean values were used. The analysis and descriptive part of the work were carried out by means of the Microsoft Excel spreadsheet software package.Results: The outcomes of hospitalization of patients with suspected or confirmed diagnosis of COVID-19 were significantly worse than in other patients. Moreover, the frequency of lethal outcomes increases significantly in correlation with the age of patients and does not depend on the choice of treatment method – surgical or therapeutic.Conclusion: COVID-19 significantly complicates provision of medical care in conditions of the round-the-clock hospital for blood circulatory system diseases. The risks of surgical interventions for circulatory system diseases in combination with COVID-19 are as high as with the use of therapeutic technologies. It is necessary to unify the indications and contraindications to surgical treatment of conditions related to acute coronary syndrome in cases of the presence of such concomitant pathology as COVID-19.
