Evaluation of right ventricular function in patients with coronary artery heart disease before and after percu-taneous coronary intervention using PW-tissue Doppler imaging and M-mode echocardiography
Abstract：Objective To observe the changes of right ventricular function in patients with coronary artery heart disease( CHD ) before and after percutaneous coronary intervention ( PCI ) .Methods TA Sa, Tei index, TAPSE and RVFAC were evaluated in 77 patients with CHD before and after PCI.Additionally, TA Sa, Tei index, TAPSE and RVFAC were evaluated in 64 health volunteers.Results Before intervention, TA Sa and TAPSE of pa-tients with CHD were less than those of the health volunteers, Tei index was more than those of the health volunteers, and the differences were statistically significant ( P<0.05 ) .After intervention, TAPSE of patients with CHD was more than before,Tei index of patients with CHD was less than before, and the differences were statistically significant ( P<0.05);TA Sa and TAPSE of patients with CHD were less than those of the health volunteers, Tei index was more than those of the health volunteers, and the differences were statistically significant(P<0.05).TA Sa had a close correlation with TAPSE(r=0.641, P<0.01),TA Sa and TAPSE had a close correlation with Tei index(r=-0.542, P<0.01;r=-0.570, P<0.01).Conclusion TA Sa and TAPSE have a close correlation with Tei index, playing a significant role in estimating the short-term changes of right ventricle function before and after PCI in patients with CHD.
