Survival curves of patients with COVID-19 with and without cardiac injury on admission and receiver operating characteristic curve analysis for plasma hs-TnI levels as a predictor of death. (A) Kaplan–Meier curves with cumulative hazards of death for comparison of patients with and those without cardiac injury. The mortality rate was higher in patients with cardiac injury on admission compared with those without cardiac injury on admission. (B) Receiver operating characteristic (ROC) curve and the area under the ROC curve for plasma hs-TnI levels on admission to predict death.
