The coronavirus disease 2019 (COVID-19) pandemic has greatly impacted the US healthcare system. Cardiac involvement in COVID-19 is common and manifested by troponin and natriuretic peptide elevation and tends to have a worse prognosis. We analyzed patients who presented to the MedStar Health system (11 hospitals in Washington, DC, and Maryland) with either an ST-elevation myocardial infarction (STEMI) or non-ST-elevation myocardial infarction (NSTEMI) early in the pandemic (March 1, 2020 – June 30, 2020) using the International Classification of Diseases, Tenth Revision. Patients’ clinical course and outcomes, including in-hospital mortality, were compared on the basis of the results of COVID-19 status (positive or negative). The cohort included 1533 patients admitted with an acute myocardial infarction (AMI), of whom 86 had confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, during the study period. COVID-19-positive patients were older and non-White and had more co-morbidities. Furthermore, inflammatory markers and N-terminal-proB-type-natriuretic peptide were higher in COVID-19-positive AMI patients. Only 20.0% (17) of COVID-19-positive patients underwent coronary angiography. In-hospital mortality was significantly higher in AMI patients with concomitant COVID-19-positive status (27.9%) than in patients without COVID-19 during the same period (3.7%; p<0.001). Patients with AMI and COVID-19 tended to be older, with more co-morbidities, when compared to those with an AMI and without COVID-19. In conclusion, myocardial infarction with concomitant COVID-19 was associated with increased in-hospital mortality. Efforts should be focused on the early recognition, evaluation, and treatment of these patients.
