Association of Traditional Risk Factors with Coronary Calcification in Persons with a Family History of Premature Coronary Heart Disease: The Study of the Inherited Risk of Coronary Atherosclerosis

Abstract

In a cohort of subjects specifically selected for the characteristic of a family history of premature CHD, traditional risk factors accounted for less than one-third of the variation in CAC, and the most important predictors of CAC after age were plasma triglycerides. This supports the opinion that other inherited risk factors have important effects on the variation in coronary atherosclerosis and that the strategy of using EBT to phenotype clinically asymptomatic subjects with regard to coronary atherosclerosis may be a useful tool for identification of genes that are associated with CHD.
