RT Journal A1 Wilson PF T1 Homocysteine and coronary heart disease: How great is the hazard? JF JAMA JO JAMA YR 2002 FD October 23 VO 288 IS 16 SP 2042 OP 2043 DO 10.1001/jama.288.16.2042 UL http://dx.doi.org/10.1001/jama.288.16.2042 AB In this issue of THE JOURNAL, 2 meta-analyses critically review the coronary heart disease (CHD) risks related to blood levels of homocysteine and a common variant of methylene tetrahydrofolate reductase (MTHFR), a gene that is known to be an important regulator of homocysteine metabolism.1- 2 The authors summarize data on the potential effects of this genetic variant and plasma homocysteine levels on CHD risk and conclude that the risks are increased modestly. While the authors do not recommend new approaches to evaluate persons at risk for CHD, the study findings do provide a perspective on how scientists assess the utility of newer biomarkers and genetic factors that may contribute to CHD risk.
