  1. Univariate and multivariate Cox regression analyses were constructed with forward step-wise variable selection. HR hazard ratio, CI confidence interval. Covariates included age (year), sex (male, 1; female, 2); NYHA functional class III-IV (0, I-II; 1, III-IV); sinus rhythm in electrocardiogram (no, 0; yes, 1); BNP (pg/mL), eGFR (mL/min/1.73 m2), hemoglobin (g/dL), total bilirubin (mg/dL), uric acid (mg/dL) and C-reactive protein (mg/dL), echocardiographic parameters such as LAD (cm), IVSTd (cm), LVDd (cm), LVEF (%), RVFAC (%), RVOT-FS, TR-PG (mmHg); use (no, 0; yes, 1) of beta-blocker, ACE-I/ARB, calcium channel blocker, diuretic and aldosterone antagonist.
