Abstract:
Objective To create a three-dimensional speckle tracking imaging (3DSTI) multiparameter analysis model to improve the diagnostic efficiency of obstructive coronary artery stenosis.Methods One hundred and four patients with chest pain were divided into two groups:coronary heart disease(CHD) group (61 patients) and control group (43 patients) according to the result of selective coronary angiography (SCA).The two groups' clinical data and echocardiographic parameters were aquired,including mitral flow E and A velocities,E peak deceleration time,isovolumic relaxation time (IVRT),mitral annulus velocity e' and a' peak in diastolic and s' peak in systolic by tissue Doppler imaging (TDI),and left ventricular ejection fraction (LVEF).The global longitudinal peak strain (2D-GLPS) by two dimensional speckle tracking,global longitudinal peak strain (3D-GLPS),circumferential peak strain(3D-GCPS),radial peak strain (3D-GRPS) and area peak strain (3D-GAPS) were acquired.Results For conventional parameters,there were no significant difference between the two groups.Compared with control group,TDI e' peak,3D-GRPS decreased,significantly E/e',2D-GLPS,3D-GLPS,3D-GAPS,3D-GCPS increased significantly (P ＜0.01).For single parameter,area under the ROC curve (AUC) were successively 3D-GAPS(0.766) ＞ 3D-GLPS(0.746) ＞ 2D-GLPS(0.746) ＞3D-GRPS(0.727) ＞ s' (0.703) ＞E/e' (0.688)＞3D-GCPS(0.686).AUC for single and multi technology were successively p-Union(0.856)＞p-3DSTI(0.772) ＞ p-TDI (0.757) ＞ p-2DSTI (0.746).Conclusions 3DSTI together with multi-parameter analysis model can significantly improve the diagnostic efficiency of obstructive coronary artery stenosis.Area strain is an independent predictor of obstructive coronary artery stenosis.
