摘　　要：目的探讨ST段抬高型心肌梗死(STEMI)经皮冠状动脉支架置入术后患者彩超下左心房容积指数(LAVI)检测的意义及其与复发心房颤动的关系。方法选取2019年5月至2021年5月萍乡市人民医院收治的82例经皮冠状动脉支架置入术治疗的STEMI患者作为研究对象,根据术后随访结果是否复发心房颤动分为未复发组(n=61)与复发组(n=21)。比较STEMI患者治疗前后左心房参数[左心房容积(LAV)、LAVI、左心室射血分数(LVEF)及左心房内径(LAD)],比较两组左心房参数,采用多元Logistic回归分析STEMI患者术后复发心房颤动的影响因素。结果治疗后,患者LAV、LAVI、LAD低于治疗前,而LVEF高于治疗前,差异有统计学意义(P<0.05)。复发组LAV、LAVI大于未复发组,LAD长于未复发组,LVEF低于未复发组,差异有统计学意义(P<0.05)。多元Logistic逐步回归分析结果显示,LAVI、LAV、LAD是心房颤动复发的危险因素(OR>1,P<0.05),而LVEF心房颤动复发的保护因素(OR<1,P<0.05)。结论经皮冠状动脉支架置入术可改善STEMI患者心肌结构,且术后心房颤动复发与左心房参数相关,临床可根据LAV、LAVI及LAD指标的监测,为疾病诊治及术后预防心房颤动复发提供依据,值得临床推广。Objective To investigate the significance of left atrial volume index(LAVI)detected by color Doppler ultrasound in patients with ST elevation myocardial infarction(STEMI)after percutaneous coronary stent implantation and its relationship with recurrent atrial fibrillation.Methods 82 STEMI patients treated with percutaneous coronary stent implantation in Pingxiang People's Hospital from May 2019 to May 2021 were selected as the research subjects,they were divided into the non-recurrence group(n=61)and the recurrence group(n=21)according to the post-operative follow-up results.The left atrial parameters(left atrial volume[LAV],LAVI,left ventricular ejection fraction[LVEF]and left atrial diame-ter[LAD])of STEMI patients before and after treatment were compared,left atrial parameters were compared between the two groups,multivariate Logistic regression was used to analyze the influencing factors of postoperative recurrent atrial fibrillation in STEMI patients.Results After treat-ment,LAV,LAVI and LAD were lower than those before treatment,while LVEF was higher than that before treatment,the differences were statisti-cally significant(P<0.05).The LAV and LAVI in the recurrence group were larger than those in the non-recurrence group,the LAD was longer than that in the non-recurrence group,and the LVEF was lower than that in the non-recurrence group,the differences were statistically significant(P<0.05).Multivariate Logistic stepwise regression analysis showed that LAVI,LAV and LAD were risk factors for recurrence of atrial fibrillation(OR>1,P<0.05),while LVEF was the protective factor for recurrence of atrial fibrillation(OR<1,P<0.05).Conclusion Percutaneous coronary stent implantation can improve the myocardial structure of STEMI patients,and the recurrence of atrial fibrillation after operation is related to left atrial pa-rameters,clinically,according to the monitoring of LAV,LAVI and LAD indicators,it can provide a basis for disease diagnosis and treatment and postoperative prevention of atrial fibrillation recurr
