不同剂量美托洛尔治疗心肌梗死的疗效及对患者心功能、心率的影响研究(1)
摘要:目的 探讨不同剂量美托洛尔治疗心肌梗死的疗效及对患者心功能、心率的影响。方法 从2014年1月~2016年12月在本院接受治疗的心肌梗死患者中随机选取116例作为研究对象,按照随机数字抽取表法进行分组,两组各58例,其中A组患者在常规综合治疗的基础上采用高剂量美托洛尔治疗;而B组患者则采用低剂量美托洛尔治疗,对两组患者治疗前后胸痛发作次数及持续时间进行分析,并观察心率、心功能改善情况等。结果 治疗后对照组和观察组胸痛发作次数及持续时间均降低,其中以观察组改善程度更加显著,P<0.05;观察组患者左心室射血分数显著高于对照组,而左心室收缩末期容积显著低于对照组,P<0.05。结论 对心肌梗死患者采用高剂量美托洛尔治疗利于获得较高的疗效,利于改善患者心功能,且心率稳定,安全性,值得推广应用。

Abstract:Objective To investigate the effect of different doses of metoprolol on myocardial infarction and its effect on cardiac function and heart rate.Methods From January 2014 to December 2016,116 patients were randomly selected from our patients with myocardial infarction.The patients were divided into two groups according to the random number extraction method.Two groups of 58 cases,of which group A patients in the conventional comprehensive treatment based on the use of high-dose metoprolol treatment; and group B patients were treated with low-dose metoprolol,the two groups of patients before and after treatment of chest pain episodes and duration of the analysis,and observe the heart rate,heart function improvement and so on.Results After treatment,the number and duration of chest pain were decreased in the control group and the observation group,the improvement degree of the observation group was more significant,P<0.05;the left ventricular ejection fraction of the observation group was significantly higher than that of the control group,while the left ventricular end-systolic volume significantly lower than the control group,P<0.05. Conclusion The high dose of metoprolol in patients with myocardial infarction can improve the curative effect and improve the heart function,and the heart rate is stable and safe.It is worthy to be popularized and applied.

心肌梗死主要是由于心肌缺血引起的心肌急性壞死,主要表现为胸骨后剧烈疼痛、循环功能障碍等,给患者带来巨大的痛苦[1]。急性心肌梗死在老年群体中发病率较高,如何进行有效的治疗成为临床研究重点。当前药物治疗中以美托洛尔应用比较普遍,其能够有效控制症状发作,但由于大部分患者存在机能衰退、药物吸收和排泄有限情况,因此需要合理控制药物使用剂量,以获得良好的疗效[2]。为此,本次研究对不同剂量美托洛尔治疗心肌梗死的疗效及对患者心功能、心率的影响进行了探讨,并选择116例患者作为研究对象,报道如下。
1 资料与方法
1.1一般资料
本次研究选择了116例心肌梗死患者作为研究资料,均为本院于2014年1月~2016年12月收治。均满足《急性ST段抬高型心肌梗死诊断和治疗指南》,发病时间≤24 h[3]。采用随机数字抽取表法对患者进行分组,其中对照组共58例,男32例,女26例,年龄58~78岁,平均年龄(69.06±3.71)岁;观察组共58例,男30例,女28例,年龄56~78岁,平均年龄(68.95±3.65)岁。排除相关药物过敏患者、陈旧性心肌梗死病史患者、合并严重低血压患者及具有出血倾向患者等。对两组患者的基本资料进行比较分析,均无显著性差异(P>0.05)。
1.2方法
1.2.1对照组 给予患者实施常规综合治疗,包含吸氧支持、抗凝、溶栓、扩张冠状动脉等,并给予患者低剂量美托洛尔缓释片(生产厂家:安徽万森制药有限公司,批准文号:国药准字H20066315)治疗,初始剂量为 2次/d,12.5 mg/次,逐渐增加至2 次/d,25 mg/次,维持该剂量1 w。, 百拇医药(李江波)
