ABSTRACT
Objective To evaluate the impact of carvedilol and metoprolol on left ventricular (LV)dyssynchrony in idiopathic dilated cardiomyopathy(IDC).Methods In this study,we randomly assigned 65 IDC patients from January 2009 to June 2011 to re-ceive carvedilol or metoprolol succinate.All patieats were divided in to carvedilol group(n=33)and metoprolol group(n=32)Echo-cardiographic measurements and N-terminal pro-brain natriuretic peptide levels were obtained at baseline and 6 month after thera-py.Then long-term follow up the survival rate of patients were observed.Results In carvedilol group,reduction in LVEDS and in-crease in LVEF was higher compared to metoprolol group.Also improvement in LV dyssynchrony achieved and survival rate with carvedilol was higher than metoprolol.However,Improvements in LV mechanical dyssynchrony was similar in two groups.Im-provements in LV mechanical dyssynchrony achived with both drugs were accompanied by reduction in NT-pro-BNP levels in both carvedilol and metoprolol groups(P >0.05).Conclusion Carvedilol is an effective drug improves the intraventricular dyssynchro-nyfor for IDC patients with left ventricular dyssynchrony,and could increasea the survival rate.
