Abstract

Objective: We aimed to investigate both the impact of COVID-19 pandemic on ST-segment elevation myocardial infarction (STEMI) admission, and demographic, angiographic, procedural characteristics, and in-hospital clinical outcomes of patients with COVID-19 positive STEMI in Turkey.

Methods: This was a multi-center and cross-sectional observational study. The study population included 1788 STEMI patients from 15 centers in Turkey. The patients were divided into two groups: COVID-19 era (March 11st-May 15st, 2020; n = 733) or pre- COVID-19 era group (March 11st-May 15st, 2019; n = 1055). Also, the patients in COVID-19 era were grouped as COVID-19 positive (n = 65) or negative (n = 668).

Results: There was a 30.5% drop in STEMI admission during COVID-19 era in comparison to pre-COVID-19 era. The patients admitted to the medical centers during COVID-19 era had a longer symptom-to-first medical contact time [120 (75-240) vs. 100 (60-180) minutes, p < 0.001]. COVID-19 positive STEMI patients had higher thrombus grade and lower left ventricular ejection fraction compared to COVID-19 negative patients. COVID-19 positive patients had higher mortality (28% vs. 6%, p < 0.001) and cardiogenic shock (20% vs. 7%, p < 0.001) rates compared with those without COVID-19. Matching based on propensity scores showed higher mortality and high thrombus grade in STEMI patients who were infected by SARS-COV-2 (each p < 0.05).

Conclusions: We detected significantly lower STEMI hospitalization rates and significant delay in duration of symptom onset to first medical contact in the context of Turkey during the COVID-19 outbreak. Moreover, high thrombus grade and mortality were more common in COVID-19 positive STEMI patients.
