Abstract:
Objective To observe the value of speckle-tracking imaging (STI) in evaluation on degree of coronary artery stenosis in patients with coronary artery disease (CAD).Methods Totally 74 CAD patients,including 59 with coronary artery stenosis (coronary artery stenosis group) and 15 without coronary artery stenosis (no coronary artery stenosis group) underwent STI and echocardiography.Based on Gensini scores,the patients in coronary artery stenosis group were further divided into mild,moderate and severe subgroups.The average global longitudinal strain (GLS-Avg),basement global longitudinal strain (GLS-Bas),middle global longitudinal strain (GLS-Mid) and apical global longitudinal strain (GLS-AP) value were measured and compared.Results GLS-Avg,GLS-Bas,GLS-Mid and GLS-AP value in coronary artery stenosis group were lower than those in no coronary artery stenosis group (all P ＜ 0.001).In coronary artery stenosis group,with the increase of stenosis severity,GLS-Avg,GLS-Bas,GLS-Mid and GLS-AP value decreased,and statistical differences were found between each two subgroups (all P＜0.05).In coronary artery stenosis group,there were positive correlations between GLS-Avg,GLS-Bas,GLS-Mid,GLS-AP value and Gensini scores (r=0.861,0.847,0.819 and 0.778,all P＜ 0.05).Conclusion GLS value of STI can reflect the severity of coronary artery stenosis in CAD patients.
