Abstract

Highlights

The article presents the results of analysis of hospital morbidity and mortality in patients with cardiovascular diseases receiving specialized medical care at the Department of Infectious Diseases of the Kuzbass Clinical Cardiology Dispensary named after Academician L.S. Barbarash.

 

Aim. To analyze hospital morbidity and mortality in patients with new coronavirus infection (NCI) who received specialized medical care at the Department of Infectious Diseases of the Kuzbass Clinical Cardiology Dispensary named after Academician Barbarash.

Methods. The object of the study were the reports of the head of the Department of Infectious Diseases regarding patients with circulatory system diseases (CSD) and NCI receiving care at the Kuzbass Cardiology Center for the period from 10.21.2020 to 30.06.2022. The subject of the retrospective study were the types of CSD and mortality (ICD-10 code) in treated patients. The unit of analysis – treated patients with CSD (18 years and older) and NCI (U07.1 and U07.2).

Results. Data of 1 248 patients with CSD and NCI were analyzed. The highest number of such cases occurred in 2021, accounting for more than half of all patients treated at the Department. More than half of the patients were hospitalized with acute coronary artery disease (CAD), less than a quarter of the patients were hospitalized with chronic CAD and heart failure. Acute coronary syndrome (ACS) was verified in 38.9% of patients, stroke in 22.4% of patients, and pulmonary embolism in 1.8% of patients (n = 22). Patients were more often admitted with acute (primary) myocardial infarction (MI) and unstable CAD (17.6% and 15%, respectively), and half as often with recurrent MI (6.3%). Less than 40% of patients were hospitalized due to chronic CSD, among which prevailed chronic CAD and decompensated chronic heart failure (CHF) (19.7%). Mortality was 16%, mortality within 24 hours was 2.5%. The mean age of the deceased patients was 72.69 ± 12.22 years. The proportion of patients of working age who died was 10.8 times lower than that of patients older than working age. On average, women were 1.1 times more likely to die during the analyzed period. Acute CSD (32.3%), chronic CSD (33.5%) and stroke (34.2%) caused death at an equal rate.

Conclusion. Patients with ACS and stroke were the majority of treated patients. Patients were more often admitted with primary MI and unstable CAD, and half as often with recurrent MI. The most predominant chronic CSD were chronic CAD and decompensated CHF. One sixth of all treated patients died. Acute and chronic CSD and stroke caused death at an equal rate.
