目的探索心绞痛并发急性心力衰竭应用美托洛尔静脉注射治疗的临床疗效。方法 125例心绞痛并发急性心力衰竭患者,随机分为观察组(62例)和对照组(63例)。对照组采用常规治疗,观察组在对照组基础上给予美托洛尔静脉注射治疗。对比两组疗效。结果观察组总有效率为93.55%,明显高于对照组的84.13%;观察组治疗后左室射血分数(LVEF)、心排血量(CO)均高于对照组;观察组患者的心绞痛缓解时间明显短于对照组,心力衰竭缓解率高于对照组,差异均有统计学意义(P<0.05)。结论在心绞痛并发急性心力衰竭中运用美托洛尔静脉注射治疗,有助于提高临床效果,改善患者的心功能,值得临床推广使用。
Objective To explore the clinical efficacy of intravenous metoprolol in patients with angina pectoris complicated by acute heart failure. Methods A total of 125 patients with angina pectoris complicated with acute heart failure were randomly divided into observation group (62 cases) and control group (63 cases). The control group received routine treatment, and the observation group received metoprolol intravenously on the basis of the control group. Compare two groups curative effect. Results The total effective rate in the observation group was 93.55%, significantly higher than 84.13% in the control group. The left ventricular ejection fraction (LVEF) and cardiac output (CO) in the observation group were significantly higher than those in the control group. The angina pectoris The remission time was significantly shorter than the control group, and the remission rate of heart failure was higher than that of the control group (P <0.05). Conclusions Intravenous injection of metoprolol in angina pectoris complicated with acute heart failure can improve the clinical effect and improve the cardiac function of patients. It is worth to be used clinically.
