目的 探讨PCI术前高负荷阿托伐他汀对AMI患者临床预后的影响.方法 连续性收录80例AMI患者,分为负荷组40例和对照组40例,负荷组术前应用高负荷阿托伐他汀,综合分析两组患者PCI术后血脂和心功能改变情况.结果 负荷组患者术后第7天BNP水平明显低于对照组[(204±60.3)ng/L与(328.3±67.5) ng/L,t=1.938,P=0.031],术后1个月可见负荷组患者LVEF水平明显优于对照组[(50.3±6.0)%与(56.9±7.3)%,t=2.169,P=0.019].他汀类药物负荷治疗与PCI术后第7天BNP水平呈轻度负相关(r=-0.157,P=0.021),与PCI术后1月LVEF轻度正相关(r=0.328,P=0.026).结论 AMI患者急诊PCI术前高负荷应用他汀类药物能有效改善缺血心肌再灌注,对术中无复流现象有一定预防作用,有助于改善AMI患者心功能.
Objective To evaluate the effect of high load application of atorvastatin on the clinical outcome of patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI).Methods Eighty patients diagnosed with AMI were continuously enrolled in this study and randomly divided into two groups:high dose group(n=40) and control group(n=40).Application of high load atorvastatin before operation in loading group.The levels of serum lipid and cardiac function were measured and analyzed.Results The levels of BNP((204±60.3) pg/mL vs.(328.3±67.5) pg/mL;t=1.938,P=0.0315) on 7 days after PCI and levels of LVEF((50.3±6.0)% vs.(56.9±7.3)%;t=2.169,P=0.019) on 1 month after PCI in high dose group were significantly better than those in control group.Correlation analysis showed that the administration of statin was negatively associated with levels of BNP(r=-0.157,P=0.021) on 7 days after PCI and positively associated with LVEF(r=-0.328,P=0.026) on 1 month after PCI.Conclusion The treatment of high dose statin before PCI may reduce the ischemia-reperfusion injury and prevent the no-reflow development,which therefore improve the cardiac function of AMI patients.
