The effects of Shexiang Baoxin pills combined with intracoronary injection of nicorandil on myocardial blood perfusion and short-term prognosis for STEMI patients after PPCI

目的观察麝香保心丸联合冠脉内注射尼可地尔对ST段抬高型心肌梗死(ST-segment elevation myocardial infarction,STEMI)患者PPCI术后心肌血流灌注及近期预后的影响。方法入选2017年1月至2018年1月就诊联勤保障部队第九〇〇医院行直接经皮冠状动脉介入治疗(PPCI)术后的STEMI患者共151例,按随机数字法分为常规治疗组(A组)51例、冠状动脉内注射尼可地尔组(B组)50例和麝香保心丸+冠状动脉内注射尼可地尔组(C组)50例。比较术中校正的TIMI帧数(corrected TIMI frame count,cTFC)、术后TIMI 3级血流比例、2 h心电图ST段回落>50%指数、住院期间主要心血管不良事件(major adverse cardiovascular events,MACE)发生率以及术后3个月内心绞痛等级和MACE发生率等指标。结果B、C组在术中即刻cTFC、术后2 h心电图ST段回落>50%指数均优于A组(P<0.05),C组结果优于B组;术后3个月内心绞痛分级C组优于A、B组(P<0.05)。结论麝香保心丸联合冠脉内注射尼可地尔能够改善STEMI患者行PPCI术后心肌血流灌注及近期预后。

Objective To observe the effects of Shexiang Baoxin pill combined with intracoronary injection of nicorandil on myocardial perfusion and short-term prognosis after primary percutaneous coronary intervention in patients with ST-segment elevation myocardial infarction.Methods 151 patients with acute myocardial infarction after PPCI were enrolled in this study.Those patients were admitted to our hospital during January 2017 to January 2018.According to the numerical randomization method,51 patients were selected as routine treatment group(group A),50 patients with intracoronary injection of nicorandil(group B)and 50 patients received intracoronary injection of nicorandil plus oral Shexiang Baoxin pills(group C).Intra-operative corrected TIMI frame count(cTFC),postoperative TIMI grade 3 blood flow ratio,2-hour ECG ST segment fallback>50%index,the incidence of major adverse cardiovascular events(MACE)during hospitalization and the incidence of angina and MACE within 3 months after surgery were evaluated.Results cTFC,2 hours postoperative ECG ST segment fall>50%index in group B and C were better than group A(P<0.05).The results from group C were better than group B.Group C exhibited better results than group B and C in post-operative angina pectoris 3 months after surgery(P<0.05).Conclusion Shexiang Baoxin pills combined with intra-coronary injection of nicorandil can improve myocardial perfusion and short-term prognosis after primary percutaneous coronary intervention in patients with ST-segment elevation myocardial infarction.
