Body iron status has been suggested to be related to the development of cardiovascular disease (CVD). Biologically plausible mechanisms for this association have been described, however epidemiological studies on iron status and CVD risk have provided conflicting results. The lack of consistency is likely explained by differences in the study design, the measures used for the assessment of iron status, the definition of outcomes, and adjustment for confounders. To help clarify the available evidence, we report a systematic review of published cross-sectional, longitudinal, and intervention studies evaluating the relationship between different measures of iron status and CVD risk. The most likely scenario that emerges from the available studies is that, in the reference range, iron status has a neutral effect. Extreme conditions of iron deficiency, as well as of iron overload, are associated with modestly increased CVD risk, although with different proposed mechanisms. [ABSTRACT FROM AUTHOR] |
