This study found that during the COVID-19 pandemic, patients presenting for ST-elevation myocardial infarction (STEMI) were more likely to present late and have lower left ventricle ejection fraction (LVEF) on presentation.
- From January 1, 2020, to April 15, 2020, 143 STEMIs were identified across our integrated 18‐hospital system.
- The cut-off for pre‐ and post‐COVID‐19 cohorts was March 23rd, 2020, when stay‐at‐home orders were initiated in Ohio.
- Compared with the pre‐COVID‐19 cohort, post‐COVID‐19 patients had a significantly lower initial LVEF (45 [34–50] vs. 50% [40–60], p = .015)
- 11/35 patients with STEMI in the post-COVID group presented > 12 hr after symptoms onset. Of these, 27% avoided the ED due to fear of COVID‐19, 18% believed symptoms were COVID‐19 related, and 9% did not want to burden the ED given the COVID‐19 pandemic
- Among post‐COVID‐19 patients, those with >12‐hr delay in presentation had a longer average door-to-balloon time (88 vs. 53 min, p = .033) and higher peak troponin (58 vs. 8.5 ng/ml, p = .03)
