Abstract
Background Recent studies have suggested that knowledge of the extent of subclinical atherosclerosis may improve prognostic information in subjects at risk of cardiovascular disease. Therefore, we tested the value of extracoronary plaque detected with echography at multiple sites and that of total coronary calcification deposit evaluated with ultrafast computed tomography for predicting the risk of coronary events estimated on the basis of traditional risk factors. Methods and Results We analyzed in 618 asymptomatic at-risk men the extent of extracoronary atherosclerosis, as assessed with ultrasound imaging of carotid, aortic, and femoral sites and coded as number of disease sites (none, one, two, or three) on the basis of the presence of plaque at each site, and the amount of total coronary calcification deposit, as evaluated with ultrafast computed tomography and coded as grade 0, 1, 2, or 3 on the basis of the determination of a total coronary calcium score. Concomitantly, age, systolic pressure, total...
