Abstract 17471: Outcome of Acute Myocardial Injury in COVID-19 Patients

Background: Acute myocardial injury has been reported in approximately 20% of patients with Coronavirus disease 2019 (COVID-19). Little is known about the outcome of this subset of patients. We are testing the hypothesis of higher morbidity and mortality in patients with COVID-19 who have acute myocardial injury. Methods: In this retrospective study, we analyzed data from patients admitted to Steward Healthcare hospitals in Massachusetts between March 22 and April 24, who tested positive for COVID-19 confirmed by serology and found to have elevated troponin levels (>0.01). The sociodemographic information, clinical data, and outcomes of these critically ill patients were retrospectively extracted from the medical records. The primary outcome was in-hospital death. Data were analyzed using JMP statistical analysis software. Results: Two hundred eighty-three COVID-19 positive patients were found to have troponin levels >0.01 on admission. Of these 183 patients (64.6%) were males, 49.1% were Caucasian and 32.1% were African Americans. The mean age of the patients was 70.7 ± 13.8. The prevalence of comorbid conditions was as follows: hypertension, 69.7%; hyperlipidemia, 46.9%; diabetes mellitus, 42.6%; chronic kidney disease, 28.3%; heart failure, 19.3%; atrial fibrillation, 22.1%; coronary artery disease, 17.1%; cerebrovascular accident, 10.2%; obesity, 38%; chronic obstructive pulmonary disease or asthma 20.8%, obstructive sleep apnea, 4.9%. One hundred thirty-seven patients (48.4%) noted to have acute kidney injury on presentation,128 (45.2%) required ICU level of care, 41% required invasive mechanical ventilation for a mean of 10.4 ± 7.9 days, and 38.8% required vasopressors. The average length of stay (LOS) in the medical intensive care unit and the hospital was 11.5 ± 8.3 days and 11.4 ± 9.5 days respectively. The overall in-hospital mortality rate was 45.6%. Conclusion: Patients with COVID-19 and elevated Troponin levels had high morbidity and mortality
