Abstract:
Objective To determine which parameters of reverse remodeling of left ventricular could become the effective indexes in evaluating the short-term therapeutic effect of cardiac resynchronization therapy(CRT)in heart failure(HF)patients.Methods CRT was performed in 26 HF patients with dysfunctions of wall motion.Serial echocardiography was practiced at baseline,one and three months after CRT.The parameters including left atrial end-diastolic diameter(LADD),left ventrieular end-diastolic diameter(LVDD),end-diastolic volume (LVEDV),end-systolic volume(LVESV),ejection fraction(LVEF)were measured and compared before and after CRT therapy.Results At one and three months after CRT,respectively,CRT was associated with reduced LADD,LVDD,LVEDV,LVESV and improved LVEF and filling time compared with those at baseline.Moreover,all these parameters had better correlations with the activities of these patients.Conclusions LADD,LVDD,LVEDV,LVESV and LVEF could become the effective indexes in evaluating the short-term effect of CRT in HF patients.The reduced diameters and volumes of left atria and left ventricle are more sensitive parameters than the improved LVEF.
