Effect of COVID-19 pandemic on six-month mortality and clinical outcomes of patients with ST-elevation myocardial infarction

Introduction: The coronavirus disease 2019 (COVID-19) infection has changed everyday clinical practice, with a shortage of solid data about its implications for ST-elevation myocardial infarction (STEMI) patients. Aim: To evaluate the impact of COVID-19 on 6-month clinical outcomes of patients with STEMI and determine the mortality predictors after STEMI during the COVID-19 pandemic. Material and methods: This prospective observational study was conducted on consecutive STEMI patients who presented to our hospital between April and October 2021. A total of 74 COVID-19-positive patients were included in group I and compared to 148 COVID-19-negative patients (group II). We compared the two cohorts' rates of major adverse cardiovascular events (MACEs; composite of death from any cause, recurrent MI, target-vessel revascularization, and stroke) at 6 months. Results: = 0.001). The independent predictors of 6-month mortality in STEMI patients during the COVID-19 pandemic were the absence of ST resolution, low systolic blood and higher Killip class on admission, presence of severe MR and atrial fibrillation, and anterior wall STEMI. Conclusions: STEMI patients with superimposed COVID-19 infection had worse clinical outcomes, with almost three times higher in-hospital mortality and 6-month MACEs.
