Myocardial Injury and Major Adverse Outcomes in Patients With COVID-19

Description

The study team's understanding of diagnosis, treatment and outcomes of coronavirus disease 2019 (COVID-19) is rapidly evolving. First reports from China clearly indicate that older patients with underlying cardiovascular disease and/or cardiac risk factors demonstrate higher mortality rates. Most recent reports provided novel insights into the incidence of myocardial injury in COVID-19 patients and its association with adverse outcomes. In both studies, patients with myocardial injury manifested by elevated high-sensitivity troponin I (TnI) levels had significantly higher in-hospital mortality rates compared with those without myocardial injury, (59.6 and 8.9% (3) and 51 vs 4.5 %). Among patients with myocardial injury, higher levels of TnI were associated with higher mortality rates. While the highest mortality rates were observed in patients with elevated TnI and underlying cardiovascular disease (CVD), mortality rates were also considerable in patients with elevated TnI and without prior CVD. In contrast, patients with known cardiovascular disease without TnI elevation had more favorable outcomes. Cardiac injury was independently associated with an increased risk of mortality in patients with COVID-19. The arming reports clearly indicate that the data from larger populations from multiple centers are needed to further characterize and better understand the association between myocardial injury and adverse outcomes in COVID-19 patients.

II. STUDY AIM The aim of the proposed study is to analyze the incidence, clinical outcomes and predictors of myocardial injury in a large patient population with COVID-19 treated in Mount Sinai Hospital (MSH) system. In addition, the study team will explore the association between TnI levels and clinical characteristics, biomarkers, cardiac tests data and treatment approaches to uncover the potential mechanisms responsible for COVID-19 induced myocardial injury.

III. STUDY POPULATION As of April 6, 2020, there have been 1,917 COVID-19 positive patients treated in the Mount Sinai Hospital (MSH) and more than 1,1000 patients with COVID-19 had been healed and discharged. All consecutive patients admitted to the MSH system from February 2020 to April 2020 with laboratory-confirmed COVID-19 will be included in the retrospective study.
