Observe the Clinical Effect of Metoprolol in Treatment of Patients With Angina Pectoris Complicated With Acute Heart Failure

目的观察心绞痛并发急性心力衰竭患者应用美托洛尔治疗的临床效果。方法选择心绞痛并发急性心力衰竭患者92例,随机分为实验组和对照组,对照组实施常规治疗,实验组实施常规治疗联合美托洛尔,比较两组患者的临床效果。结果实验组患者的左心射血分数、心排量高于对照组,心肌耗氧量低于对照组,治疗总有效率(89.1%)高于对照组(69.6%),上述指标对应比较,差异有统计学意义(P<0.05)。结论心绞痛并发急性心力衰竭患者应用美托洛尔治疗,具有较好的治疗效果。

Objective To observe the clinical effect of metoprolol in treatment of patients with angina pectoris complicated with acute heart failure. Methods 92 patients with angina pectoris complicated with acute heart failure were randomly divided into experimental group and control group. Routine treatment was performed in the control group. Routine treatment combined with metoprolol was performed in the experimental group. The clinical effect of the two groups was compared. Results Patients in the experimental group left ventricular ejection fraction and cardiac output was higher than the control group, the myocardial oxygen consumption is lower than the control group, the total efficiency of treatment （89.1%） was higher than the control group （69.6%）, comparing the corresponding index, the difference was statistically significant （P 〈 0.05）. Conclusion Angina pectoris complicated with acute heart failure in patients with metoprolol treatment, has a good therapeutic effect.
