Data are presented as the mean and standard deviation or median and interquartile range. EF: ejection fraction; LVEDD: left ventricular end-diastolic diameter; LVOTG: left ventricular outflow tract gradient; nsVT: nonsustained ventricular tachycardia; SCD: sudden cardiac death; STD: septal thickness at end diastole.
