The question of homocysteine's link with heart disease has reared its head once again.
Recently, several studies have indicated that blood levels of homocysteine could be an independent predictor of heart disease. However, in the July 21 issue of Circulation: Journal of the American Heart Association, researchers at the University of Minnesota Medical School in Minneapolis reported that they did not find a causal relationship between homocysteine levels and heart disease.
