Abstract: Objectives: The aim of this study is to assess the aortic elasticity in relation to the severity of coronary stenosis in patients with coronary heart disease (CHD). Methods: The study included 50 persons divided into three groups: based on the severity of coronary stenos measured by coronary angiography (CAG). All subjects underwent full history taking, complete clinical examination, echocardiographic examination, full laboratory data, ECG and coronary angiography. Results: Among study population 22 female (44.0%) and 28 male (56.0%) with mean age (55.530 ± 6.802) There was considered extremely statistically significant between the three groups as regard aorta stiffness index was greater in moderate and severe stenos groups than the slight stenos group (P<0.0004), whereas dispensability index showed the opposite trend (P<0.0001). the two indexes changed in a stepwise pattern with the narrowness of coronary artery, Conclusion: The elasticity indexes of ascending aorta correlate closely with the severity of coronary stenosis, positive correlation between Gensini scoring of coronary artery narrowing and stiffness index of ascending aorta. In contrast, dispensability index was negatively correlated with Gensini score.
