目的探讨临床上使用美托洛尔治疗慢性心力衰竭的实际疗效。方法随机将50例慢性心力衰竭患者分为实验组和常规组,每组数量一致。对常规组患者采用常规治疗方式进行治疗,对实验组患者加用美托洛尔进行治疗,并就治疗前后两组患者的心率和左心室射血分数进行比较观察。结果实验组患者的治疗效果明显要比另一组患者的治疗效果要好,且其心率和左心室射血分数明显要优于常规组患者,相比之下差异较大(P<0.05),具有统计学意义。结论临床上使用美托洛尔治疗慢性心力衰竭的实际疗效显著,患者的治疗有效率非常高且患者不会出现明显的不良反应,此方法值得在今后的临床工作中进一步推广应用。
Objective To investigate the clinical efficacy of metoprolol in the treatment of chronic heart failure. Methods 50 patients with chronic heart failure were randomly divided into experimental group and conventional group, with the same number in each group. The patients in the conventional group were treated by conventional treatment, and the patients in the experimental group were treated with metoprolol. The heart rate and left ventricular ejection fraction were compared between the two groups before and after treatment. Results The therapeutic effect of the experimental group was significantly better than that of the other group, and its heart rate and left ventricular ejection fraction were significantly better than those of the conventional group (P <0.05) Statistical significance. Conclusion The clinical curative effect of metoprolol in the treatment of chronic heart failure is remarkable. The treatment efficiency is very high and the patient does not have obvious adverse reactions. This method is worth further promotion in the future clinical work.
