摘　　要：目的:探讨急性心肌梗死(Acute myocardial infarction,AMI)患者经皮冠状动脉介入治疗(Percutaneous coronary intervention,PCI)后二维应变超声评估左室心肌功能的临床价值。方法:选取2018年9月至2020年12月医院收治的72例AMI患者为研究对象,患者PCI后均获得6m随访结果,全部患者在术后第3 d接受二维应变超声检查,记录参数(左心室整体径向应变(Global radial strain,GRS)、整体纵向应变(Global longitudinal strain,GLS)、整体周向应变(Global circumferential strain,GCS))。评估患者治疗后6 m预后情况并分组,分析二维应变超声参数检查结果AMI患者PCI治疗后预后价值。结果:全部72例患者经评估,26例预后不良,占36.11%;预后不良组GRS、GLS、GCS均小于预后良好组(P<0.05);二维应变超声GRS、GLS、GCS单独及联合评估AMI患者PCI治疗后预后不良的曲线下面积(Area under the curve,AUC)分别为0.840、0.810、0.834、0.910,均有一定评估价值,且当GRS、GLS、GCS分别取29.99%、11.18%、10.86%时,其敏感度以及特异度较高。结论:AMI患者在接受PCI治疗后获得二维应变超声检查结果,对患者预后风险有一定预测价值,可考虑将其用于风险预测及治疗指导。Objective:To explore the clinical value of two-dimensional strain echocardiography in evaluating left ventricular myocardial function in patients with acute myocardial infarction(AMI)after percutaneous coronary intervention(PCI).Method:72 AMI patients admitted to the hospital from September 2018 to December 2020 were selected as the study subjects.After PCI,all patients received 6-month follow-up results.All patients underwent two-dimensional strain echocardiography examination on the third day after surgery,recording parameters such as global radial strain(GRS),global longitudinal strain(GLS),and global circumferential strain(GCS)of the left ventricle.The prognosis of patients 6 months after treatment was evaluated and grouped,and the prognostic value of two-dimensional strain echocardiography parameters in patients with AMI after PCI was analyzed.Result:After evaluation,26 out of 72 patients had poor prognosis,accounting for 36.11%.The GRS,GLS,and GCS of the poor prognosis group were all lower than those of the good prognosis group(P<0.05).The area under the curve(AUC)of two-dimensional strain echocardiography GRS,GLS and GCS alone and in combination to evaluate the poor prognosis of AMI patients after PCI were 0.840,0.810,0.834 and 0.910,respectively,all of which had certain evaluation value.When GRS,GLS and GCS were 29.99%,11.18%and 10.86%,respectively,the sensitivity and specificity were higher.Conclusion:The two-dimensional strain echocardiography examination results obtained by AMI patients after PCI treatment have certain predictive value for the prognosis risk of patients,and can be considered for risk prediction and treatment guidance.
