Executive Summary

"A low plasma concentration of vitamin C was not associated with an increased risk of acute myocardial infarction, irrespective of smoking status," researchers at the Royal Infirmary of Edinburgh and the University of Edinburgh report in the American Journal of Clinical Nutrition. Rudolph Riemersma, et al., measured the plasma vitamin C concentrations of 180 AMI survivors over a two-year period. Although levels immediately following the heart attack were lower than the control group's, they were similar after recovery. An accompanying editorial states researchers "have not resolved whether vitamin C has beneficial effects in coronary artery disease" and suggests the need for "properly designed interventional studies"
