Impact of adding a single allele in the 9p21 locus to traditional risk factors on reclassification of coronary heart disease risk and implications for lipid-modifying therapy in the Atherosclerosis Risk in Communities (ARIC) study

摘要

BackgroundA single nucleotide polymorphism on chromosome 9p21, rs10757274 (9p21 allele), has been shown to predict coronary heart disease (CHD) in whites. We evaluated whether adding the 9p21 allele to traditional risk factors (RF) improved CHD risk prediction in whites from the Atherosclerosis Risk in Communities (ARIC) study, and whether changes in risk prediction would modify lipid therapy recommendations.
