Abstract:Aim To evaluate the values of applying echo-tracking technique in aged patients with coronary heart disease (CHD). Methods We enrolled 108 aged patients with CHD as the CHD group. Fifty healthy volunteers were enrolled as the control group. CHD patients were classified into two groups according to the findings of coronary angiography: one-vessel lesion group (47 cases) and multi-vessel lesion group (61 cases). For all subjects, indexes of arterial elasticity including pressure-strain elasticity modulus (Ep), wall stiffness index (β), one-point pulse wave velocity (PWVβ) and arterial compliance (AC) were measured with echo-tracking, and then compared among study groups. Results The Ep, β, PWVβ of carotid artery in CHD group were significantly greater than that in the control group (P<0.05). The Ep, β, PWVβ in multi-vessel lesion group were significantly greater than that in one-vessel lesion group (P<0.05). There was no difference of AC among various groups. Conclusions Indexes of carotid artery elasticity including Ep, β, PWVβ were closely associated with the occurrence and development of CHD. Echo-tracking can be an effective technique for the evaluation of CHD.
