Hospitalized patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) community-acquired pneumonia (CAP) and associated comorbidities are at increased risk of cardiovascular complications. The magnitude of effect of cardiovascular complications and the role of prior comorbidities on clinical outcomes are not well defined.What is the impact of cardiovascular complications on mortality in hospitalized patients with SARS-CoV-2 CAP? What is the impact of co-morbidities and other risk factors on the risk of developing cardiovascular complications and mortality in these patients?This cohort study included 1,645 hospitalized patients with SARS-CoV-2 CAP. Cardiovascular complications were evaluated. The clinical course during hospitalization was described using a multistate model with 4 states: hospitalized with no cardiovascular complications, hospitalized with cardiovascular complications, discharged alive, and dead. Cox proportional hazards regression was used to analyze the impact of prior comorbid conditions on transitions between these states. Hazard ratios (HRs) and 95% confidence intervals (CIs) were reported.Cardiovascular complications occurred in 18% of patients hospitalized with SARS-CoV-2 CAP. The mortality rate in this group was 45% versus 13% in patients without cardiovascular complications. Males (HR: 1.32, 95% CI: 1.03-1.68), older adults (HR: 1.34, 95% CI: 1.03-1.75), patients with congestive heart failure (HR: 1.59, 95% CI: 1.18-2.15), coronary artery disease (HR: 1.34, 95% CI: 1.00-1.79), atrial fibrillation (HR: 1.43, 95% CI: 1.06-1.95), direct admissions to the ICU (HR: 1.77, 95% CI: 1.36-2.32) and PaO
