LA/Ao - left atrial size-to-aortic root diameter ratio; RWT - relative wall thickness; LWd + LWs - sum of maximum left ventricular wall thickness, IVSd/LWd - relative interventricular septal thickness; ST IVS - interventricular septal systolic thickening; ST LW left ventricular free wall thickening. Values are displayed as mean ± standard deviation.
