LEFT ATRIAL TO LEFT VENTRICULAR END SYSTOLIC VOLUME INDEX RATIO BY ECHOCARDIOGRAPHY CAN PREDICT ELEVATED LEFT ATRIAL PRESSURE IN HEART FAILURE WITH PRESERVED EJECTION FRACTION

Our aim was to determine if an increased left atrium (LA) to left ventricle (LV) size ratio in end systole (ventricular) on 2D echocardiography (Echo) is a marker of elevated LA pressure (LAP) in heart failure with preserved ejection fraction (HFPEF), as LA is relatively dilated and LV cavity size
