摘　　要：目的:研究急诊经皮冠脉介入治疗(percutaneous coronary intervention,PCI)治疗急性心肌梗死对QT离散度(Q-T dispersion,QTd)及脑尿钠肽(brain natriuretic peptide,BNP)影响。方法:对2015年1月-2017年3月在笔者所在医院心内科住院的96例急性心肌梗死患者进行回顾性分析,其中对照组62例,采取择期PCI治疗;观察组34例,采取急诊PCI治疗。分别对两组患者治疗前、治疗后1周及治疗后3个月QTd、BNP、左室收缩末内径(left ventricular end systolic diameter,LVESD)及左室舒张末期内径(left ventricular end diastolic diameter,LVEDD)进行比较。结果:两组患者治疗前QTd、BNP比较差异无统计学意义(P>0.05);观察组患者治疗后1周QTd、BNP相比对照组明显降低,差异有统计学意义(P<0.05),左室收缩末内径及左室舒张末期内径比较差异无统计学意义(P>0.05);观察组患者治疗后3个月QTd、BNP、左室收缩末内径及左室舒张末期内径相比对照组均明显降低,差异均有统计学意义(P<0.05)。结论:临床上对急性心肌梗死患者行急诊PCI治疗,能有效缩短QT离散度,减低BNP,减轻左心室重构的程度,改善预后。Objective:To study the influence of emergency PCI in patients with acute myocardial infarction on QTd and BNP.Method:From January 2016 to March 2017,96 cases of acute myocardial infarction hospitalized were analyzed,and divided into two groups.62 cases of the control group were treated by selective PCI,and 34 cases in the observation group were treated with emergency PCI.The QTd,BNP,left ventricular end systolic diameter and left ventricular end diastolic diameter of the two groups were compared.Result:After treatment in the hospital,the QTd and BNP in the observation group were significantly lower than those in the control group,the differences were statistically significant(P<0.05).There was no significant difference in left ventricular end systolic diameter and left ventricular end diastolic diameter(P>0.05).The QTd,BNP,left ventricular end systolic diameter and left ventricular end diastolic diameter in the observation group were significantly lower than those in the control group at 3 months after treatment,the differences were statistically significant(P<0 05).Conclusion:In clinic,emergency PCI treatment for acute myocardial infarction patients can shorten QT dispersion,reduce BNP,reduce the degree of left ventricular remodeling,which is worthy of clinical promotion.
