The Claim
Plasma ferritin levels are positively associated with myocardial infarction and cardiovascular mortality in age- and sex-adjusted models, but these associations are no longer statistically significant after adjustment for traditional cardiovascular risk factors including obesity, alcohol use, inflammation, and lower education, indicating that plasma ferritin is not an independent predictor of these outcomes.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Higher plasma ferritin levels are linked to increased risk of heart attack and death from cardiovascular disease when only age and sex are considered, but this link disappears when accounting for obesity, alcohol use, inflammation, and lower education, meaning ferritin does not independently predict these outcomes.

Excess iron in the blood triggers inflammation and disrupts how the body processes fats and sugars, which damages blood vessels and increases the chance of heart attacks. When other risk factors like obesity and alcohol use are present, they cause the same damage, so iron alone doesn't add extra risk.
What the research says
1 studyStudy: Red meat consumption and risk of cardiovascular diseases-is increased iron load a possible link?
Higher iron levels (ferritin) seem linked to heart attacks when you only look at age and sex, but once you account for things like being overweight, drinking alcohol, or having less education, that link goes away — meaning ferritin isn’t causing heart problems on its own.
