Data are mean ± SD unless stated otherwise. BMI indicates body mass index; SBP, systolic blood pressure; DBP, diastolic blood pressure; IVSD, interventricular septum in diastole; LVPWD, left ventricular posterior wall in diastole; LVIDD, left ventricular internal diameter in diastole; RWT, relative wall thickness; LVM, left ventricular mass; LVMI, left ventricular mass index (LVM/height 2.7).
