In-hospital mortality analysis in patients with acute cardiovascular pathology and co-infection with COVID-19: a registry of one site

Funding Acknowledgements Type of funding sources: None. Patients with cardiovascular pathology have a significantly higher risk of adverse events and death when complicated by concomitant COVID-19. The aim of this study was to analyze in-hospital mortality in pts with acute cardiovascular pathology (ACP) and a co-infection with COVID-19. 139 pts with ACP who were diagnosed with COVID-19 were examined. 69 (49.6%) pts had ACS (47 pts with AMI), 33 (23.7%) pts - hypertensive urgency, 24 (17.3%) pts - ADHF, 9 (6.5%) pts - tachysystolic paroxysm of atrial fibrillation, 2 (1.4%) pts - acute pulmonary embolism, and 2 (1.4%) pts - syncope. The average age was 67.9±12.7 y.o., 70 (50.4%) pts were male. Concomitant arterial hypertension was found in 87.1%, DM – 20.9%, CHF - 30.9%, COPD – 9.4% of pts, history of AMI – 20.1% and ischemic stroke – 9.4% of pts. In 79 (56.8%) pts COVID-19 was diagnosed and laboratory confirmed before hospitalization (hospitalized in 5.3±3.6 days after symptoms onset). 31 (22.3%) pts were diagnosed with COVID-19 upon admission, and 29 (20.9%) - during their stay in the hospital. 20 (15.6%) pts were vaccinated against COVID-19. The initial SpO2 level was 91.6±10.3%, while more than half of pts (53.2%) had SpO2 During the hospital period, 20 (14.4%) pts died. The mortality rate was 28.0% in pts with ADHF, 19.1% in pts with AMI and significantly less in pts hospitalized for unstable angina, hypertensive urgency or atrial fibrillation - 5.2% (p Co-infection with COVID-19 worsens treatment outcomes and in-hospital mortality of patients with ACP. Vaccination significantly reduces the likelihood of complications and tends to reduce mortality.
