*Hazard ratio (HR) and 95% CI. Only variables with P < 0.10 on univariable analyses were included in multivariable models. ACEI: angiotensin-converting enzyme inhibitor; ARB: angiotensin receptor blocker; Biv: Biventricular; CI: confidence intervals; FMR: functional mitral regurgitation; HR: hazard ratio; LAD: left atrial diameter; LVEDV: left ventricular end-diastolic volume; LVEF: left ventricular ejection fraction; LVESV: left ventricular end-systolic volume; NYHA class: New York Heart Association functional class; SRs: super responders.
