目的 探究疏血通注射液对急性高龄心肌梗死患者PCI术后临床疗效的影响.方法 将我院接受PCI(经皮冠脉介入)术治疗的60例急性高龄心肌梗死患者作为研究对象,并给予随机分组,对照组30例,给予常规治疗;观察组30例,在对照组基础上加用疏血通注射液治疗,对两组患者治疗前后血液流变学、心功能指标以及不良心血管事件发生情况进行综合评价.结果 观察组患者治疗后的红细胞聚集指数、血小板聚集率等血液流变学指标显著优于对照组(P＜0.05),有统计学意义;观察组治疗后的NT-proBNP、cTnT等心功能指标与对照组呈现明显差异(P＜0.05),有统计学意义;且观察组治疗后仅发生2起不良心血管事件,占6.7％,显著低于对照组的26.7％,两组差异有统计学意义(P＜0.05).结论 疏血通注射液在急性高龄心肌梗死患者PCI术中的应用,能够促进血液流变学改善,对心功能具有保护作用,减少心血管事件的发生,值得推广应用.“,”Objective To explore the effect of Shuxuetong injection on postoperative clinical efficacy of PCI in eldly patients with acute myocardial infarction.Methods 60 cases ofeldly patients with acute myocardial infarction were randomly divided into control group and treatment group,30 cases in each group.Control group was given conventional treatment,treatment group was given Shuxietong injection on the basis of control group.Blood rheology,heart function index and adverse cardiovascular events before and after treatment were evaluated.Results After treatment,blood rheological indexes of erythrocyte aggregation and platelet aggregation rate in treatment group were significantly higher than those in control group,the difference was statistically significant (P＜0.05).The cardiac function indexes ofnt-probnp and cTnT of treatment group were significantly different from control group,the difference was statistically significant (P＜0.05).Two adverse cardiovascular events occurred after treatment in observation group,accounting for 6.7％,significantly lower than 26.7％ of control group,the difference was statistically significant (P＜0.05).Conclusion Shuxuetong injection is effective in treatment of acute myocardial infarction in eldly patients,the application of PCI surgery can improve the blood rheology,possess protective effects on cardiac function and reduce the happening of cardiovascular events,it is worthy of popularization and application.
