Relationship of Plasma Level of Vitamin C to Mortality from Ischemic Heart Disease

The present epidemiological data support and extend previous evidence in men and animals. Thus, a poor plasma status of vitamin C (less than 23 microM = 0.4 mg/dl) and/or of cholesterol-standardized vitamin E (less than 20-21.5 microM = 9 mg/l) occurs in westernized countries with an increased risk of IHD. A poor status in the major essential antioxidants may be a hitherto underrated, at least permissive, risk factor of IHD that could, at least in some European countries, substantially complement the previously established risk factors such as hypercholesterolemia.
