Data presented as number (%) for categorical variables, and as median (interquartile range) for continuous variables. a The denominators for these calculations were the number of patients with no CRT at baseline (N = 504). Abbreviations: CRT = cardiac resynchronization therapy; iLVEDD = indexed left ventricular end-diastolic diameter; iLVESD = indexed left ventricular end-systolic diameter; LVEF = left ventricle ejection fraction; LVRR = left ventricular reverse remodelling.
