Abstract:
Objective To investigate left ventricular systolic function with mitral annulus motion velocity(Sa) with pulsed-wave Doppler tissue imaging(PW-DTI) in patients with coronary arteriosclerosis disease(CAD) after percutaneous coronary intervention(PCI).Methods 52 patients with CAD,who were determined by coronary artery angiography,were divided into two groups,PCI group(n=33) and non-PCI group(n=19).They were followed up with PW-DTI and conventional echocardiography before and 5 d,3 months and 6 months after intervention in PCI ones,before and 6 months after angiography in non-PCI ones.In PCI group,the patients were divided two subgroups: EF≥50% and EF=30%～50%.Results The Sa improved significantly in PCI group 6 months after intervention(P<0.001).EF correlated with Sa(r=0.705,r=0.770 pre-and post-intervention respectively,P<0.0001).Conclusion Sa can be used to evaluate left ventricular systolic function of CAD patients.
