目的评价美托洛尔静注治疗心绞痛并发急性心力衰竭的应用价值。方法研究选择我院收治的心绞痛并发急性心力衰竭患者1500例,患者均于2015年1月份到2016年1月份入院治疗。随机性分组,对照组予以常规治疗,共750例;实验组同时予以美托洛尔治疗,共750例。观察和比较两组患者的治疗效果。结果在总有效率方面,实验组为98.7%(740/750),对照组为73.3%(550/750),实验组总有效率比对照组高,组间数据差异性明显且统计学意义成立(P<0.05);在心功能、血液流变学方面,患者治疗后LEVF、CO以及耗氧量均得到改善,且实验组优于对照组,组间数据差异性明显且统计学意义成立(P<0.05)。结论应用美托洛尔对心绞痛并发急性心力衰竭患者进行治疗,能够改善患者的心功能、血液流变学,且安全性高,值得推荐。
Objective To evaluate the clinical value of metoprolol intravenous injection in the treatment of angina pectoris complicated by acute heart failure. Methods A total of 1 500 patients with angina pectoris complicated with acute heart failure admitted to our hospital were selected and admitted to our hospital from January 2015 to January 2016. Randomized group, the control group to be routine treatment, a total of 750 cases; experimental group metoprolol at the same time, a total of 750 cases. Observed and compared the treatment effect of two groups of patients. Results The total effective rate was 98.7% (740/750) in the experimental group and 73.3% (550/750) in the control group. The total effective rate in the experimental group was higher than that in the control group, and the difference between the two groups was statistically significant (P <0.05). In terms of cardiac function and hemorheology, the LEVF, CO and oxygen consumption of patients after treatment were all improved, and the experimental group was better than the control group. The differences of the data between the two groups were significant and statistically significant (P <0.05). Conclusion The application of metoprolol in the treatment of patients with angina pectoris complicated with acute heart failure can improve the cardiac function and hemorheology of patients with high safety and is worth recommending.
