a

significant difference (P < 0.05). E/A = ratio of the peak early to late transmitral flow velocity, E’/A’(lateral) = ratio of the peak early to late lateral mitral annular filling velocity, E’/A’(medial) = ratio of the peak early to late medial mitral annular filling velocity, HCM = hypertrophic cardiomyopathy; IVSd = interventricular septal wall thickness during diastole; LA/Ao (lax) = left atrial diameter to left aortic root diameter ratio from right parasternal long-axis view, LA/Ao (sax) = left atrial diameter to left aortic root diameter ratio from right parasternal short-axis view; LVPWd = thickness of left ventricular posterior wall during diastole, OCD = other cardiac disease, VAo = peak velocity for aortic flow
