  1. IVS - interventricular septum thickness, LVID – left ventricular internal diameter, LPW – left posterior wall thickness, LPWs –left ventricular posterior wall in end-systole, FS – fractional shortening, EF – ejection fraction.
  2. Values are displayed as mean ± standard deviation.
  3. N = 170.
