DCM, dilated cardiomyopathy; HFrEF, heart failure with reduced ejection fraction; iLVEDD, indexed left ventricular end‐diastolic diameter; LVEDV, left ventricular end‐diastolic volume; LVEF, left ventricular ejection fraction; LVESV, left ventricular end‐systolic volume; LVRR, left ventricular reverse remodelling; NICM, non‐ischaemic cardiomyopathy.
