  1. Note: Continous variables are expressed in terms of mean ± SD. The weighted linear regression model was used to determine the P value. Categorical variables are presented in terms of %. The weighted chi-square test was used to determine P value. SBP, systolic blood pressure; DBP, systolic blood pressure; MAP, mean arterial pressure; SPO2, pulse oxygen saturation; BUN, blood urea nitrogen; Cr, creatinine; WBC, white blood cell; BNP, B-type natriuretic peptide; AST, aspartate transaminase; CHD, coronary heart disease; ARDS, acute respiratory distress syndrome; COPD, chronic obstructive pulmonary disease, BNP: B-type natriuretic peptide, LVEF: left ventricular ejection fraction, diuretic, ACEI/ARB/ARNI, cardiac glycoside.
