美托洛尔治疗慢性心力衰竭的临床研究

目的：观察美托洛尔在慢性心衰中的应用效果。方法：将200例患者分为强化组和常规组，常规组采用常规治疗方法，强化组在此基础上并给予美托洛尔治疗。结果：强化组有效率87.0%，明显优于常规组71.0%。强化组患者治疗后的心率为（62.3±5.8）次/min，左心室射血量为（57.1±2.6）%；常规组患者治疗后的心率为（86.2±7.6）次/min，左心室射血量为（38.6±7.8）%。结论：慢性心衰在基础治疗中同时使用美托洛尔可获得更好的效果，安全性较好。

Clinical Study on Metoprolol in Treating Chronic Heart Failure

Objective： To investigate the application results of metoprolol in patients with chronic heart failure.Method：200 cases were randomly divided into intensive group and conventional group, the conventional group was treated by conventional treatment method. On this basis, the intensive group was given metoprolol. Result： The effective rate of the intensive group was 87.0%, which was more higher than that of the conventional group 71.0%. After treatment, the patient’s heart rate of the intensive group was （62.3±5.8） beats/min, left ventricular stroke volume was （57.1±2.6）%. Patient’s heart rate of the conventional group was （86.2±7.6） beats/min, left ventricular stroke volume was （38.6±7.8）%.Conclusion：On the basis of conventional therapy, patients with chronic heart failure will get better results, better security with metoprolol.
