Abstract: Objective To investigate the relationship between Tel index and the extent of coronary artery disease.Methods 100 cases who underwent quantitative coronary angiography(QCA)were enrolled in this study,Frequency spectntm of blood flow of mitral valve and aortic valve was gathered in Pulse Doppler.from which Tei index was calculated.Results 70 patients of 100 cases with coronary angiography were diagnosed coronary heart disease 70%(70/100);coronary angiography in 30 patients with negative excluded coronary heart disease;with the degree of coronary artery stenosis increased Tei index rising trend(0.39±0.03～0.48±0.06):Severe coronary artery stenosis Tei index(0.48±0.06)than the mild coronary artery stencsis(0.42±0.05)increased significantly(q=3.21,P＜0.05),but mild coronary artery stenosis(0.42±0.05)and no narrow group(0.39±0.03)there was no significant difference(q=2.21,P＞0.05);A comparison of Tei index between Gensini integral 41 to 80 cent.≥81 cent and 40 cent were significant different(q=3.28、3.31,all P＜0.05).Conclusion Tei index was postive correlated with the extent of coronary artery disease.
