摘要: Background—Elevated plasma total homocysteine (tHcy), low B-vitamin intake, and genetic polymorphisms related to tHcy metabolism may play roles in coronary heart disease (CHD). More prospective studies are needed. Methods Results—We used a case-cohort design determine whether tHcy-related factors associated with incidence of CHD over an average 3.3 years follow-up biracial sample middle-aged men women. Age-, race-, field center–adjusted was positively (P<0.05) women but not men, negatively folate (women only), pyridoxal 5′-phosphate (both sexes), vitamin supplementation only). However, after accounting for other risk factors, only incidence; the relative highest versus lowest quintile 0.28 (95% CI=0.1 0.7). There no association C677T mutation of...
