Abstract:
Grade Ⅲ),preserved LV ejection fraction(EF%≥55%) were involved in present study.TDI and echocardiograms were performed at baseline and during the follow-up period(the time interval between the examinations was 650?362 days).These patients were divided into 2 groups according to the interval LV end-systolic volume(LVESV) with or without 20% increment.Results Corrected by body-surface area,the biplane LVESV,LV end-diastolic volume(LVEDV) and left atrial volume(LAV) increased significantly compared with that of baseline(20?6ml/m2 vs.17?5ml/m2;55?13ml/m2 vs.49?12ml/m2 and 42?11ml/m2 vs.36?14ml/m2,respectively,P
