Abstract：Objective To study the predictive value of myocardial performance(MP)combined with three-dimensional speckle tracking imaging(3D-STI)to the severity of coronary artery stenosis.Methods The patients with first-time diagnostic angina pectoris(AP,n=121)in accordance with diagnostic and internalized standard were chosen from Department of Cardiovascular Medicine in Yantai Affiliated Hospital of Binzhou Medical University from Jan.2022 to June 2022.All patients were given examination of coronary angiography(CAG)after receiving non-stress speckle tracking echocardiography 24 h before CAG.The patients were divided,according to CAG results,whether coronary lumen stenosis been≥50%or not,into control group(n=65)and case group(n=56).The parameters of MP and global longitudinal peak strain(GLPS)and post systolic time(Tpss)of 3D-STI were compared between 2 groups.Results The global work efficiency(GWE),global work index(GWI),and global effective work(GCW)were significantly lower,and global ineffective work(GWW)was significantly higher in case group than those in control group(P<0.05).The results of ROC curve analysis showed GCW with AUC=0.662(95%CI:0.582～0.773,P=0.001),GWI with AUC=0.684(95%CI:0.609～0.793,P<0.001),GWE with AUC=0.790(95%CI:0.715～0.874,P<0.001)and GWW with AUC=0.685(95%CI:0.608～0.796,P<0.001).Among them,GWE was the most significant in predicting coronary artery stenosis with GWE<91.5%being the diagnostic critical value,sensitivity 62.5%and specificity 83.1%.In 17-segment model for analyzing left ventricular systolic function,Tpss of anterior wall mid-segment of 2-chamber view extended significantly in case group compared with control group(P<0.05).Conclusion GWE is a significant factor for diagnosing coronary artery lesions in patients with unstable angina pectoris,and Tpss in 3D-STI has diagnostic significance to anterior descending branch stenosis.GWE combined with Tpss can objectively review left ventricular function and make preliminary judgments on the diseased vessels.
