  1. Data are shown as a number (%) or mean ± S.D. HR = heart rate; LAD = left atrial dimension; IVST = interventricular septal thickness; PWT = posterior wall thickness; LVDd = left ventricular end-diastolic diameter; LVDs = left ventricular end-systolic diameter; SV = stroke volume; LVFS = left ventricular fractional shortening; LVMI = left ventricular mass index; DCT = deceleration time of the E-wave; E velocity = peak early mitral flow velocity; A velocity = peak late mitral flow velocity; E/A = ratio of mitral E and A. IVST and PWT in the LVH group were longer and LVMI was higher compared to the respective values in the control group. LVDd, LVDs, LVFS, E velocity, A velocity, E/A did not differ between the two groups.
