Warning: Should Not be Taken After a Heart Attack
A number of studies have demonstrated that arginine supplementation can be of benefit to patients with cardiovascular disease, and arginine supplementation has been recommended to patients with angina, hypertension and heart failure. One clinical trial, however, Patients for the Vascular Intervention with Age and Myocardial Infarction (VINTAGE MI), appeared to demonstrate an increased risk of death among patients who had recently suffered a myocardial infarction and were on arginine supplementation. This double-blind, placebo-controlled trial involved 153 patients In six months there were six patient deaths among the group given 9 g of arginine daily, while they were no deaths in the placebo group. These results appeared to be the opposite of findings published by Nobel prize winner Louis Navarro who has published a number of papers linking arginine supplementation with improved cardiovascular health. To firmly establish the validity of these findings, additional confirmatory studies need to be conducted. Until such time, it is our recommendation that patients who have recently suffered a myocardial infarction (heart attack) not take arginine supplementation.
