[摘要] 目的 研究卡维地洛对缺血性心脏病心肌收缩力及预后的临床疗效。方法 选取缺血性心脏病CHF 64例,随机分为倍他乐克组(A组,32例)和卡维地洛组(B组,32例),A组和B组在常规药物治疗、病情稳定基础上分别加用倍他乐克和卡维地洛,调整剂量稳定,随访3个月后回医院检测各项指标。结果 卡维地洛组和倍他乐克组均能有效降低心率,降低血压,减少左心室LVEDD、LVESD,但前者的LVESD较后者低(P<0.05),Dd值较后者高(P<0.05)。倍他乐克组可以明显地减少CO和CI,而卡维地洛组CO和CI变化不明显,两组比较差异有统计学意义(P<0.05)。两者均可提高每搏输出量和LVEF值,但与治疗后倍他乐克组比较,卡维地洛组有较高的每搏输出量(P<0.05)和LVEF值(P<0.01)。结论 卡维地洛比倍他乐克的临床疗效好,是一种安全、有效的CHF新药。

[Abstract] Objective To explore the effects and safety of Carvedilol on cardiac contractility in ischemic heart disease with the chronic congestive heart failure (CHF).Methods Sixty-four patients with CHF were randomly divided into 2 groups:the Betaloc group(A group,32cases)and the Carvedilol group(B group,32 cases). The A group was treated by Betaloc,while B group by Carvedilol base on the basic treatment. Follow-up for 3 mongths and detect the index. Results Both the two groups could reduce heart rate,blood pressure,left ventricle’s LVEDD and LVESD,but the B group had the lower LVESD and higher Dd value than the A group (P<0.05). CO and CI value of group A was reduced,there was significant difference between two groups(P<0.05). Group B had the higher SV(P<0.05)and LVEF(P<0.01)than that in group A. Conclusion Carvedilol is more effective than Betaloc. It is a effective and safty treatment to chronic congestive heart failure.

缺血性心肌病(ischemic heart disease,ICM)是指冠状动脉病变引起心肌缺血、坏死,心肌局限性、弥漫性纤维化或硬化,导致心肌肥大和心功能衰竭的一种临床综合征,常因反复发生心衰和心律失常而猝死。卡维地洛为第三代β受体阻滞剂,能够同时阻滞β1、β2受体和α1受体,大规模临床试验[1]表明,卡维地洛能显著改善心衰患者的左室功能,提高LVEF值,降低心衰病死率。近年发现其能改善心衰患者的预后,但是卡维地洛治疗缺血性心脏病心肌收缩力的疗效临床报道甚少。本文观察新型β受体阻滞卡维地洛治疗缺血性心脏病慢性心功能衰竭(chronic heart failure,CHF)心肌收缩力及预后的临床疗效,现报道如下。
1 资料与方法
1.1 一般资料
选取我院2010年2~12月诊断为缺血性心脏病CHF的患者64例,随机分为倍他乐克组(A组,32例)和卡维地洛组(B组,32例),其中A组男22例,女10例,年龄(57.45±8.56)岁,心功能NYHA分级:Ⅱ级10例,Ⅲ级14例,Ⅳ级8例。B组男21例,女11例,年龄(56.56±10.43)岁;心功能NYHA分级:Ⅱ级9例,Ⅲ级15例,Ⅳ级8例。两组年龄、性别和心功能分级差异无统计学意义(P>0.05),具有可比性。
