摘　　要：目的探讨二维超声斑点追踪成像(spottracking imaging,STI)应用于非ST段抬高型急性心肌梗死(non-ST segment elevation acute myocardial infarction,NSTEAMI)临床诊断工作中的具体价值。方法回顾性选取2021年3月—2023年4月于菏泽市中医医院就诊的120例急性心肌梗死患者的临床资料为研究组,同期体检的120例健康人群的临床资料为对照组。两组均行STI检查。对比研究对象的STI检查结果,包括梗死节段心内膜、梗死节段心外膜、整体收缩期峰值纵向应变(longitudinal peak systolic strain,LPSS)、峰值环向应变(circumferential peaksystolic strain,CPSS)等。结果研究组整体、梗死节段心内膜、梗死节段心外膜LPSS、CPSS均高于对照组,差异有统计学意义(P均<0.05)。研究组NSTEAMI患者梗死节段心内膜、梗死节段心外膜LPSS、CPSS均低于ST段抬高型急性心肌梗死(ST segment elevation acute myocardial infarction,STEAMI)患者,差异有统计学意义(P均<0.05)。NSTEAMI患者整体LPSS、CPSS分别为(-19.38±3.08)%和(-17.40±4.51)%,低于STEAMI患者的(-12.25±1.41)%、(-13.98±2.83)%,差异有统计学意义(t=16.304、4.975,P均<0.05)。结论应用STI对NSTEAMI病情具有一定的辅助诊断价值。Objective To investigate the specific value of two-dimensional ultrasound spottracking imaging(STI)in the clinical diagnosis of non-ST-segment elevation acute myocardial infarction(NSTEAMI).Methods The clinical data of 120 patients with acute myocardial infarction who were treated in Heze Traditional Chinese Medicine Hospital from March 2021 to April 2023 were retrospectively selected as the study group,and the clinical data of 120 healthy people who underwent physical examination during the same period were selected as the control group.Both groups underwent STI examination.The STI results of the research objects were compared,including the infarcted segment endocardium,the infarcted segment epicardium,the overall longitudinal peak systolic strain(LPSS),and the peak circumferential peak systolic strain(CPSS).Results The LPSS and CPSS of the whole,infarcted segment endocardium and infarcted segment epicardium in the study group were higher than those in the control group,and the differences were statistically significant(all P<0.05).The LPSS and CPSS of the infarcted segment endocardium and infarcted segment epicardium of NSTEAMI patients in the study group were lower than those of ST segment elevation acute myocardial infarction(STEAMI)patients,and the differences were statistically significant(all P<0.05).The LPSS and CPSS of the whole in NSTEAMI patients were(-19.38±3.08)%and(-17.40±4.51)%,respectively,which were lower than(-12.25±1.41)%and(-13.98±2.83)%of STEAMI patients,and the differences were statistically significant(t=16.304,4.975,both P<0.05).Conclusion The application of STI has a certain auxiliary diagnostic value for NSTEAMI.
