Abstract:
Objective To evaluate the left ventricular diastolic function in coronary artery disease (CAD)patients without regional wall motion abnormality by real-time three-dimensional specke tracking imaging(RT3D-STI),and to investigate the value of RT3D-STI in detecting CAD.Methods According on coronary angiography,92 patients without regional wall motion abnormality were divided into two groups:control group(n = 21 ),without coronary artery stenosis;case group (n = 50 ),coronary stenosis group. Two dimensional images and the three-dimensional full volume dynamic images of left ventricle were collected.Routine parameters and end-systolic left ventricular globle longitudinal strain (GLS),globle circumferential strain (GCS),globle area strain (GAS),globle radial strain (GRS)and corresponding strain imaging diastolic index (SI-DI)were aquired,respectively.The parameters by RT3D-STI were analyzed to diagnose coronary artery stenosis.Results Compared with control group,there were no significant difference in routine parameters,GLS,GRS,GAS and GCS(P >0.05 ).Longitudinal SI-DI(L-SI-DI),area SI-DI(A-SI-DI),radial SI-DI (R-SI-DI),circumferential SI-DI (C-SI-DI)in case group were significantly reduced compared with control group (P <0.05).The sensitivity of L-SI-DI,A-SI-DI,R-SI-DI and C-SI-DI were 90.5%,81 .0%,85.7%,81 .0%,and the specificity of them were 82.0%,78.0%,68%,56%, respectively,L-SI-DI was the best in sensitivity and specificity.L-SI-DI,A-SI-DI,R-SI-DI were significantly correlated with Gensini score (r = -0.706,-0.547,-0.410 P < 0.05 ).Conclusions RT3D-STI can quantitatively assess the early changes of left ventricular diastolic function,which has important significance for early diagnosis of coronary artery stenosis.
