Old and new risk factors for atherosclerosis and development of treatment recommendations.
1. The development of atherosclerosis, including the role of the classical and new risk factors, is briefly reviewed an emphasis on the links between some of these risk factors and atherogenesis. 2. While genetic factors are doubtlessly important, they contribute (from the population point of view) little to the overall burden of atherosclerosis. 3. Our studies on the relationship between abdominal obesity and metabolic risk factors in two ethnic groups, namely individuals of Cantonese and European background, suggest that different ranges for at least some of the risk factors should be established for specific ethnic groups (e.g. waist circumference for individuals of Chinese and European background). 4. Using the example of differences between Cantonese heterozygotes for familial hypercholesterolaemia living in Vancouver, Canada, and Canton, China, we demonstrate how the environment can modify a genetic predisposition for atherosclerosis. 5. Gender differences are illustrated by a study of serum lipoprotein (a) as a risk factor in men and women. 6. The principles of current Canadian recommendations for the assessment and treatment of atherosclerosis are outlined; they are based on knowledge gained from both basic and clinical research of atherosclerosis.
