目的：探讨美托洛尔治疗充血性心力衰竭的临床疗效。方法：选取我院2012年4月-2013年5月所接收治疗的120例充血性心力衰竭患者，依据不同的治疗方案，随机分为对照组和观察组，每组患者60例。对照组患者采用常规强心利尿剂进行治疗，观察组患者采用强心利尿剂合并美托洛尔进行治疗，对比分析两组患者的临床疗效和不良反应发生率。结果：对照组患者的总有效率为81.6%，观察组患者的总有效率为93.3%，观察组患者的总有效率显著优于对照组患者，P<0.05则具备统计学意义。对照组患者的不良反应发生率为10（16.6%），观察组患者的不良反应发生率为4（6.6%），观察组患者的不良反应发生率显著优于对照组患者，P<0.05则具备统计学意义。结论：对于充血性心力衰竭患者，采用美托洛尔进行治疗，疗效显著，不良反应率低，具有临床价值意义，可以大力推广。
Objective: To investigate the clinical efficacy of metoprolol in the treatment of congestive heart failure. Methods: A total of 120 patients with congestive heart failure treated in our hospital from April 2012 to May 2013 were randomly divided into control group and observation group with 60 cases in each group according to different treatment plans. Patients in the control group were treated with conventional cardioplegic diuretic. The patients in the observation group were treated with cardiotonic diuretic plus metoprolol, and the clinical efficacy and incidence of adverse reactions were compared between the two groups. Results: The total effective rate of the control group was 81.6%, the total effective rate of the observation group was 93.3%. The total effective rate of the observation group was significantly better than that of the control group, P <0.05 was statistically significant. The incidence of adverse reactions in the control group was 10 (16.6%), the incidence of adverse reactions in the observation group was 4 (6.6%), and the incidence of adverse reactions in the observation group was significantly better than that in the control group (P & lt; 0.05) Statistical significance. Conclusion: For patients with congestive heart failure, the use of metoprolol for treatment has significant curative effect and low adverse reaction rate, which has clinical significance and can be vigorously promoted.
