Note. The measurement data are presented as mean ± standard or median (IQR), and the count data are expressed as %. Patients are divided into three groups on the number of B-line. BMI: body mass index; SBP: systolic blood pressure; DBP: diastolic blood pressure; Hb: hemoglobin; ALB: albumin; LVEF: ejection fraction; LVEDD: left ventricular end-diastolic internal diameter; LVMI: left ventricular mass index.
