  1. BSA = body surface area, E = Transmitral E velocity e' = early diastolic velocity of the mitral, annulus, EF = Ejection fraction, LA = Left atrial, LV = Left ventricular, RV = Right ventricular, TAPSE = Tricuspid annular plane systolic excursion
  2. °Relative wall thickness calculated as (SWT - PWT)/LVIDD where LVIDD = Left ventricular internal diameter at end-diastole, PWT = Posterior wall thickness, SWT = Septal wall thickness
