Abstract：Objective To discuss the value of three-dimensional speckle tracking imaging(3D-ST1)in assessing changes of left atrial function in patients with ischemic tricuspid regurgitation(IMR).Methods The patients with coronary heart disease(CHD)undergone 3D-STI examination(n=143)were chosen from the First People's Hospital of Neijiang City from Feb.2021 to June 2023.The patients were divided,according to ultrasound examination results,into CHD group(n=55)and IMR group(n=88).Meanwhile the volunteers with physical examination(n=62)were selected into control group.The difference in 3D-STI parameter were compared among 3 groups,and correlation between 3D-STI and left atrial ejection function(LAEF)and value of 3D-ST1 parameter in IMR diagnosis were analyzed.Results In IMR group,left atrial anteroposterior diameter(LAAPD),left atrial mediolateral diameter(LAMLD),left atrial suproinferior diameter(LASID),left ventricular end-diastolic diameter(LVEDd),left ventricular end-systolic diameter(LVESd),maximum left atrial volume(LAVmax),minimum left atrial volume(LAVmin)at trough point and pre-systolic left atrial volume were higher than those in CHD group and control group(P＜0.05),and left ventricular ejection fraction(LVEF),left atrial total ejection fraction(LATEF),left atrial passive ejection fraction(LAVpEF),left atrial active ejection fraction(LAaEF),and global longitudinal strain(GLS),global circumferential strain(GCS)and global radial strain(GRS)of left atrium were lower(P＜0.05)than those in CHD group and control group.GLS,GCS and GRS were positively correlated to LATEF,LAVpEF and LAaEF in IMR group(P＜0.05).In IMR diagnosis,AUC of GLS was 0.715(95％CI:0.633-0.787,P＜0.001),AUC of GCS was 0.644(95％CI:0.559-0.722,P＜0.001),AUC of GRS was 0.643(95％CI:0.558-0.721,P＜0.001),and AUC of combination of GLS,GCS and GRS was 0.882(95％CI:0.818-0.930,P＜0.001).AUC of combination of GLS,GCS and GRS was higher than that of single GLS,GCS and GRS in IMR diagnosis(P＜0.001).Conclusion 3D-STI can accurately assess the changes of left atrial function in CHD patients with IMR,and GLS,GCS and GRS can be taken as indicators for distinguishing IMR.
