a Bar graphs illustrate the mortality of patients with/without right ventricular dysfunction (RVD) and patients with/without heart failure (HF). b Bar graphs show the prevalence of RVD and HF in patients with/without elevated high-sensitivity troponin I (hs-TNI). c Bar graphs demonstrate the incidence of RVD and HF in non-survivors and survivors. d Kaplan–Meier curves in COVID-19 patients with/without RVD and with/without elevated hs-TNI Levels. e Kaplan–Meier curves in COVID-19 patients with/without HF and with/without elevated hs-TNI Levels
