Increased mortality and worse cardiac outcome of acute myocardial infarction during the early COVID‐19 pandemic

Aims This study aimed to evaluate the impact of coronavirus disease 2019 (Covid‐19) outbreak on admissions for acute myocardial infarction (AMI) and related mortality, severity of presentation, major cardiac complications and outcome in a tertiary‐care university hospital in Berlin, Germany. Methods and results In a single‐centre cross‐sectional observational study, we included 355 patients with AMI containing ST‐elevation or non‐ST‐elevation myocardial infarction (STEMI or NSTEMI), admitted for emergency cardiac catheterization between January and April 2020 and the equivalent time in 2019. During the early phase of the Covid‐19 pandemic (e‐COV) in Berlin (March and April 2020), admissions for AMI halved compared with those in the pre‐Covid‐19 time (January and February 2020; pre‐COV) and with those in the corresponding months in 2019. However, mortality for AMI increased substantially from 5.2% pre‐COV to 17.7% (P
