目的观察β-受体阻滞剂(美托洛尔)治疗慢性充血性心力衰竭(CHF)的临床疗效。方法将96例CHF患者随机分为对照组和美托洛尔治疗组,两组均给予休息、低钠饮食,强心、利尿及扩血管等常规治疗,治疗组待病情稳定后加服美托洛尔,3个月后进行比较。结果美托洛尔治疗组心功能显著改善,心率明显降低,统计学具有显著意义。结论CHF患者在强心、利尿及扩血管等常规治疗基础上加用β-受体阻滞剂可取得更好疗效。
Objective To observe the clinical efficacy of β-blocker (metoprolol) in the treatment of chronic congestive heart failure (CHF).
