Abstract
In order to compare the extent of early carotid atherosclerosis between patients with single vascular risk factors (smoking = SMO or hypertension = HYP) and risk-free normal subjects ( = HCS), we used intimal-medial wall thickness (IMT) measurements of the common carotid artery. The age- and sex-adjusted mean IMTs were significantly higher in the HYP and SMO groups than in the HCS control group (p < 0.005 and p < 0.001, respectively). The estimated yearly progression rate of IMT (average difference in IMT/year age difference) was significantly higher in the HYP and SMO groups than in the HCS group (p < 0.05). In the total group, the age, hypertension, smoking and sex accounted for 52% of the variability of IMT. Our results show that the estimated yearly progression rate of IMT is slower in healthy and risk-free volunteers than previously detected and that the smoking and hypertension have a similar effect to the progression of early atherosclerosis. This also emphasises the influence of smoking in initial vascular remodelling process.
