Early during the COVID-19 pandemic, it was recognized that infection with SARS-CoV-2 was associated with an increased risk of both arterial and venous thrombotic complications. This association is strongest for venous thromboembolic disease, but the risk of myocardial infarction (MI) is approximately doubled in the 7 days after COVID-19 diagnosis. 1 Multiple studies have suggested worse outcomes in patients with COVID-19 and MI, 2,3 with direct effects of the virus on endothelial cells, increased propensity for vascular thrombosis, and deficient care delivery all mechanistically implicated. 4 The study by Saad et al 5 in this issue of JAMA reexamines these findings in the largest cohort yet described. Using the Vizient Clinical Database, an administrative database of more than 700 US academic hospitals and affiliates, the authors described in-hospital outcomes for patients with COVID-19 and ST-segment elevation MI (STEMI). Propensity score matching was used to compare patients with COVID-19 and STEMI with 2 separate control groups: patients without COVID-19 hospitalized with STEMI in 2020 and patients hospitalized with STEMI in 2019 before the onset of the pandemic. By comparing patients who were cared for under the same system constraints, the first comparison attempted to isolate the association between concomitant COVID-19 and STEMI outcomes, whereas the second comparison evaluated the association of both COVID-19 infection and care delivery before and after the COVID-19 pandemic with STEMI outcomes.The authors found that among 36 309 patients with outof-hospital STEMI admitted to more than 500 primary percutaneous coronary intervention (PCI)-capable hospitals in 2020, a total of 565 had concomitant COVID-19; 359 of 1937 patients with in-hospital STEMI had concomitant COVID-19. After adjusting for patient and hospital factors in the propensity score-matched analysis, 15% of patients with COVID-19 and out-of-hospital STEMI died compared with 11% of patients without COVID-19 with STEMI (odds ratio, 1.43 [95% CI, 1.10-1.86]); 77% of patients with COVID-19 and in-hospital STEMI died compared with 44% of patients without 4.11 [95% CI,). These results were similar when comparing patients with COVID-19 and STEMI vs patients without COVID-19 and STEMI from 2020 or patients with STEMI from 2019 in the pre-COVID-19 era.The study by Saad et al 5 represents an important effort to better describe MI outcomes during the pandemic, although several limitations challenge the interpretation of these data. First, the administrative database used in this study lacks granular clinical information. Although the
