title: Iron stores and the international variation in mortality from coronary artery disease.
abstract: Possible roles for iron in coronary artery disease (CAD) have emerged, including contributions to atherogenesis and/or the vulnerability of the myocardium to ischemia/reperfusion events. The value of hepatic storage iron as a potential risk factor for CAD was evaluated independently and in combination with various lipoprotein indices using CAD mortality data from 11 countries along with available data on liver iron stores. CAD mortality rates were found to be best correlated with the liver iron-serum cholesterol product in both men (r = 0.72) and, more importantly, in both genders combined (r = 0.74). It was also found that estimated CAD incidence could be related in a non-linear fashion to iron-cholesterol values in a simple normal distribution model where all subjects above a threshold value of iron-cholesterol were assumed to have CAD. Hepatic iron values thus appear to be useful in describing the differences in CAD due to both diet (and/or culture) and sex.
