| Abstract: | Stiffness of aortic walls has been shown to be a marker of coronary and cerebrovascular diseases in patients with myocardial infarction or stroke. However, its value for predicting preclinical atherosclerosis has not been demonstrated. Therefore, this study tested the association of aortic wall stiffness and coronary and extracoronary atherosclerosis in the absence of clinical cardiovascular disease.In 190 asymptomatic men at cardiovascular risk, carotid-to-femoral pulse wave velocity (PWV) was measured mecanographically and the compliance of the aorta (C), as well as the intrinsic compliance (Ci), was deduced after correction for the effect of blood pressure. Also determined noninvasively were 1) the degree of coronary calcium deposit coded as grade 0, 1, 2, or 3 using ultrafast computed tomography; 2) the extent of extracoronary plaque detected by B-mode echography at three different sites (carotid, abdominal aorta, and femoral) coded as 0, 1, 2, or 3 diseased sites; and 3) the estimated Framingham coronary risk. The grade of coronary calcium was not associated with any aortic elastic parameter. The number of extracoronary diseased sites was not associated with PWV and C but correlated negatively with Ci before but not after age adjustment. The coronary risk correlated positively with PWV and negatively with C before but not after age adjustment and was not associated with Ci.In symptom-free subjects aortic stiffening does not predict the presence of coronary and extracoronary atheroma and therefore cannot be considered as a useful surrogate marker of early atherosclerosis. |
