Table 2 Echo parameters in conventional echocardiography in the LVH and control groups

From: Midwall ejection fraction for assessing systolic performance of the hypertrophic left ventricle

Item LVH (n=30) Control (n=30) P-value

PWT (mm) 12.7±2.1 9.9±1.2 <0.0001
LVDd (mm) 43.2±4.9 43.1±4.1 0.9453
LVDs (mm) 26.5±3.9 26.9±3.4 0.6836

  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.
