摘    要:目的观察卡维地洛与关托洛尔对扩张型心肌病(DCM)患者慢性心力衰竭(CHF)的临床疗效。方法选择60例DCM伴中或重度CHF患者随机分为卡维地洛组和美托洛尔组,两组在常规治疗基础上,分别使用卡维地洛和美托洛尔治疗6个月,观察两组治疗前、治疗3个月及6个月后美国纽约心脏病协会(NYHA)心功能分级、N末端原脑利钠肽(NT-pro—BNP)、心率、收缩压及采用超声心动图测定左心室舒张末期内径(LVEDd)、左心室收缩末期内径(LVESd)和左心室射血分数(LVEF)。结果治疗3个月后与治疗前比较,两组心功能均有改善,NT—pro-BNP、心率、收缩压和LVESd降低或减小,NT-pro-BNP(1102.0±176.3)ng/L、(1219.7±213.1)ng/LVS(3107.9±446.1)ng/L、(3077.0±431.6)rig/L(均P〈O.01),心率(74.5±4.4)次/min、(77.4±3.8)次/min vs(90.5±5.1)次/min、(88.9±5.7)次/min(均P〈0.01),收缩压(114.5±7.0)mmHg、(120.1±6.6)mmHg vs(122.6±9.3)mmHg、(124.3±9.0)mmHg(P〈0.01或〈0.05),LVESd(49.2±2.7)mm、(50.6±2.4)mm vs(51.4±2.8)mm、(52.2±2.3)mm(均P〈0.05),LVEF增加(38.5±4.0)%、(36.5±3.5)%vs(32.8±3.8)%、(34.2±3.5)%(P〈0.01或〈0.05),LVEDd差异无统计学意义;治疗6个月后,两组上述参数与治疗前及治疗3个月比较差异有统计学意义(均P〈0.01)。两组治疗后上述参数比较差异有统计学意义(均P〈0.01)。两组NT-pro—BNP水平与同期测定的LVEDd、LVESd呈正相关(P〈0.05或〈0.01),与LVEF呈负相关(P〈0.01)。结论卡维地洛和美托洛尔均能显著改善CHF患者的心功能,但卡维地洛尤为明显;CHF患者NT—pro-BNP与心脏超声指标有很好的相关性,NT-pro—BNP可以作为治疗CHF的一个可靠指标。

Abstract:Objective To evaluate the long term clinical efficacy of treatment with carvedilol and metoprolol in patients of chronic heart failure(CHF) with dilated cardiomyopathy(DCM). Methods Sixty patients with DCM were randomly divided into carvedilol group and metoprolol group, which were respectively treated with carvedilol and metoprolol on the base of regular treatment. Pretherapy,and at the end of 3,6 months after treatment,comparison was made in the cardiac function, N terminal pro-brain natriuretic peptide(NT-pro-BNP), heart rate, systolic pressure, left ventricular ejection fraction(LVEF),left ventricular end diastolic dimension(LVEDd) and left ventricular end systolic dimension(LVESd). Results At the end of 3 months after treatment,both groups showed significant improvement in cardiac function, NT-pro-BNP, heart rate, systolic pressure, and LVESd significantly reduced, NT-pro-BNP ( 1 102.0 ±176.3) ng/L,(1 219.7±213.1) ng/L vs (3 107.9±446.1) ng/L, (3 077.0±431.6) ng/L (all P 〈0.01),heart rate (74.5±4.4) times/min, (77.4±3.8) times/min vs (90.5±5.1) times/min,(88.9±5.7) times/min (all P 〈0.01), systolic pressure (114.5±7.0) mm Hg,(120.1±6.6) mm Hg vs (122.6±9.3) mm Hg,(124.3±9.0) mm Hg (P〈 0.01 or 〈0.05),and LVESd (49.2±2.7) mm,(50.6±2.4) mmvs (51.4±2.8) mm,(52.2±2.3) mm (all P 〈 0.05),LVEF remarkably increased,(38.5±4.0)%, (36.5±3.5)% vs (32.8±3.8)%, (34.2±3.5)% ( P〈0.01 or〈0.05) ,while there were no statistical difference in LVEDd compared with pretherapy. At the end of 6 months after treatment, the constructive and functional parameters had a significant difference compared with those at the end of 3 months after treatment and pretherapy(all P〈0.01). These parameters had statistical difference at the end of 3,6 months after treatment between carvedilol group and metoprolol group (all P〈0.01 ). There were a positive correlation between NT-pro B
