Abstract

The coronavirus disease 2019 (COVID-19) pandemic had a significant impact on the chain of survival following cardiac arrest. However, large population-based reports of COVID-19 in patients hospitalized after cardiac arrest are limited. The National Inpatient Sample database was queried for cardiac arrest admissions during 2020 in the United States. Propensity score matching was used to match patients with and without concurrent COVID-19 according to age, race, sex, and comorbidities. Multivariate logistic regression analysis was used to identify predictors of mortality. A weighted total of 267,845 hospitalizations for cardiac arrest were identified, among which 44,105 patients (16.5%) had a concomitant diagnosis of COVID-19. After propensity matching, cardiac arrest patients with concomitant COVID-19 had higher rate of acute kidney injury requiring dialysis (64.9% vs 54.8%) mechanical ventilation >24 hours (53.6% vs 44.6%) and sepsis (59.4% vs 40.4%) compared to cardiac arrest patients without COVID-19. In contrast, cardiac arrest patients with COVID-19 had lower rates of cardiogenic shock (3.2% vs 5.4%, P < 0.001), ventricular tachycardia (9.6% vs 11.7%, P < 0.001), and ventricular fibrillation (6.7% vs 10.8%, P < 0.001), and a lower utilization of cardiac procedures. In-hospital mortality was higher in patients with COVID-19 (86.9% vs 65.5%, P < 0.001) and, on multivariate analysis, a diagnosis of COVID-19 was an independent predictor of mortality. Among patients hospitalized following a cardiac arrest during 2020, concomitant COVID-19 infection was associated with significantly worse outcomes characterized by an increased risk of sepsis, pulmonary and renal dysfunction, and death.
