【摘要】 目的:观察曲美他嗪联合经皮冠状动脉介入术(PCI)对心肌梗死患者心肌梗死溶栓试验(TIMI)血流分级及预后的影响。方法:选择2017年7月-2019年6月笔者所在医院治疗的心肌梗死患者82例,按随机数字表法分为两组,均41例。对照组接受PCI治疗,观察组则加用曲美他嗪治疗。比较两组TIMI血流分级、左心射血分数(LVEF)及并发症。结果:治疗前两组TIMI血流分级、LVEF对比,差异无统计学意义(P>0.05);治疗后观察组TIMI血流分级0级、1级、2级、3级分别为0、12.20%、24.39%、63.41%,LVEF(60.34±7.21)%,优于对照组的4.88%、17.07%、36.59%、41.46%、(53.75±5.14)%,差异有统计学意义(P<0.05);观察组并发症发生率(7.32%)低于对照组(24.40%),差异有统计学意义(P<0.05)。结论:心肌梗死患者接受曲美他嗪、PCI联合治疗安全可行,有利于改善梗死动脉血流灌注,保护心肌,改善心功能,且并发症较少。

[Abstract] Objective: To observe the effect of Trimetazidine combined with percutaneous coronary intervention (PCI) on blood flow classification and prognosis of myocardial infarction thrombolysis test (TIMI) in patients with myocardial infarction. Method: Eighty-two patients with myocardial infarction treated in our hospital from July 2017 to June 2019 were selected and divided into two groups according to the random number table method, with 41 cases each. The control group received PCI, while the observation group was treated with Trimetazidine on the basis of the control group. The TIMI blood flow grade, left ventricular ejection fraction (LVEF), and complications were compared between the two groups. Result: There were no significant difference in the TIMI blood flow grade and LVEF between the two groups before treatment (P>0.05). After treatment, the TIMI blood flow grade (grade 0, grade 1, grade 2, grade 3) were 0, 12.20%, 24.39%, 63.41%, LVEF was (60.34±7.21)% in the observation group, they were better than 4.88%, 17.07%, 36.59%, 41.46%, (53.75±5.14)% in the control group, the differences were statistically significant (P<0.05). The incidence of complications in the observation group (7.32%) was lower than that in the control group (24.40%), and the difference was statistically significant (P<0.05). Conclusion: Patients with myocardial infarction can receive Trimetazidine and PCI in combination. It is safe and feasible, and it is beneficial to improve infarct arterial blood perfusion, protect myocardium, improve cardiac function, and has fewer complications.
心肌梗死作为常见心血管疾病,多是指冠脉供血量下降、心肌灌注不足,致残、致死率较高[1]。目前经皮冠状动脉介入术(percutaneous coronary intervention,PCI)为心肌梗死治疗首选方法,利于将闭塞血管开通,促使心肌缺血时间缩短。但经临床实践发现,患者术后再灌注心肌损伤发生率较高[2]。曲美他嗪作为心肌代谢类药物,利于优化心肌代谢,保护心肌细胞,具有改善心肌缺血及心室重塑的作用[3-4]。鉴于此,本研究将观察联合曲美他嗪、PCI治疗对心肌梗死患者TIMI血流分级及预后的影响,现报告如下。
1 资料与方法
1.1 一般资料
选择2017年7月-2019年6月笔者所在医院治疗的心肌梗死患者82例,纳入标准:(1)符合文献[5]心肌梗死诊断标准:《急性冠脉综合征急诊快速诊治指南(2019)》;(2)均首次接受PCI治疗;(3)可耐受PCI、曲美他嗪治疗;(4)未合并恶性肿瘤。排除标准:(1)肝、肾功能异常;(2)患有免疫系统疾病;(3)合并心源性休克、心力衰竭;(4)患有精神疾病,或存在智力异常或意识不清,无法积极配合临床诊治。按随机数字表法分为两组,均41例。观察组:男25例,女16例;年龄46~73岁,平均(59.84±2.26)岁;病程1~8年,平均(4.37±1.02)年;合并症:高脂血症、高血压、糖尿病分别为3、10、8例。对照组:男22例,女19例;年龄46~75岁,平均(59.88±2.24)歲;病程1~8年,平均(4.39±0.98)年;合并症:高脂血症、高血压、糖尿病分别为4、12、7例。两组一般资料相比,差异无统计学意义(P>0.05),具有可比性。本研究获医学伦理委员会批准。患者签署知情同意书。
