Abstract：Objective To observe the correlation between cardiac three-dimension global strain-speckle tracking imaging (3D-STI) and SYNTAX scores or left ventricular ejection fraction (LVEF) in patients with coronary 3-vessel lesion and/or left main coronary lesion. Methods The patients (n=28) were chosen and given myocardial motion analysis by using 3D-STI. The global radial strain (GRS), global longitudinal strain (GLS), global circumferential strain (GCS) and global area strain (GAS) were calculated, and LVEF was calculated by using Simpon method. All patients were given scoring according to SYNTAX score standard. The correlation between 3D-STI indexes and SYNTAX scores or LVEF was analyzed. Results 3D-STI was negatively correlated to SYNTAX scores (r=-0.508, P<0.05), GAS was positively correlated to SYNTAX scores (r=0.569, P<0.05), and GLS and GCS was not correlated to SYNTAX scores (P>0.05). GRS, GLS, GCS and GAS were all correlated to LVEF (r=-0.742, r=-0.747, r=0.739 and r=-0.689, all P<0.01). Conclusion 3D-STI indexes and LVEF are correlated to GRS, GCS and SYNTAX scores.
