This population-based cross-sectional study included 472 apparently healthy study participants with an increased risk of cardiovascular disease, including 300 patients with hypercholesterolemia. To assess the susceptibility to the development of atherosclerosis, an ultrasonic evaluation of common carotid arteries was used. It has been confirmed that there exists the geographical gradient of carotid intima-media thickness (cIMT), and it has been shown that this gradient is highly correlated th the known gradient of cardiovascular mortality. It was found that the combination of conventional cardiovascular risk factors can help explaining only 21% variability of cIMT, the marker of generalized atherosclerosis. It was found that a predisposition to atherosclerosis, as measured by a pathological increase in cIMT, should be due to the interaction not only conventional cardiovascular risk factors, but also to genetic and environmental factors.
