Abstract:
Objective To compare the clinical efficacy of carvedilol and metoprolol in the treatment of dilated cardiomyopathy patients with heart failure (DCM).Methods According to the different treatment method,90 DCM patients with heart failure patients were divided into the observation group and the control group,45 cases in each group.Both groups were given a diuretic,vasodilator,cardiac and other drug treatment,and the control group were added with metoprolol,and the observation group were added with carvedilol.The treatment lasted 4 to 6 months.Before and after treatment,the levels of left ventricular ejection fraction(LVEF),left ventricular end-systolic diameter (LVESVI),left ventricular diastolic diameter (LVEDVI),left ventricular fractional shorteningrate (FS),largest peak velocity (hCFV),coronary flow reserve (CFR),simultaneous detection of serum levels of endothelin (ET) and nitric oxide(NO) content were observed and compared betweon the two groups.Results After the treatment,the levels of LVEF,LVESVI,LVEDVI,FS,hCFV,CFR,ET,NO of the observation group were (44.0 ± 3.4) ml/m2,(45.2 ±6.9)mm,(20.9 ±5.4)mm,(30.4 ±5.3),(78.2 ±31.6) cm/s,(3.12 ±0.36),(52.2 ±5.6) ng/L,(5.2 ± 0.67) μmol/L,respectively,which were better than those of the control group[(37.9 ± 3.5)mL/m2,(51.1 ± 7.6)mm,(20.7 ±6.3) mm,(25.2 ±7.3),(70.5 ± 31.8)cm/s,(2.85 ±0.23),(63.5 ± 1.8)ng/L,(2.55 ± 0.33) μmoL/L] (t =8.386,-3.856,-4.487,3.867,-1.152,-4.239,12.887,-23.802,all P ＜ 0.05).Conclusion Carvedilol is an effective drug for the treatment of DCM consolidated psychological failure,which can improve heart function and coronary flow reserve capacity and endothelial function in patients,which is worth in the clinical with satisfactory results.
