All the categorical variables are presented as number (percentage), and all the continuous variables were expressed by median and interquartile range (IQR). Wilcoxon rank‐sum tests weas applied to continuous variables, and chi‐square tests or Fisher's exact test were applied to categorical variables as appropriate.

Abbreviations: DBP, diastolic blood pressure at admission; hs‐cTn, high‐sensitivity cardiac troponin; ICU, intensive care unit; IL‐6, interleukin‐6; IMV, invasive mechanical ventilation; LDH, lactose dehydrogenase; BNP, B‐type natriuretic peptide; SBP, systolic blood pressure at admission.
