Association of Cardiac Injury With Mortality in Hospitalized Patients With COVID-19 in Wuhan, China

In a cohort of 416 patients hospitalized with COVID-19, nearly 20% had elevated troponins indicating myocardial injury.  These patients also had a host of other serum and radiographic abnormalities, were older, had more comorbidities, and more often required ventilatory support.  Their mortality rate was 51% compared to 4.5% for other hospitalized patients.  Elevated troponins were an independent predictor of mortality (HR 4.26).
