  1. Data are presented as ± standard deviation. Volumes are indexed to body surface area. EDD = end diastolic dimension, EDV = end diastolic volume, ESV = end systolic volume, LA = left atrial, LGE = late gadolinium enhancement, LV= left ventricular, PWT = posterior wall thickness, SWT = septal wall thickness
