It has been suggested that reperfusion accounts for up to @ % of the final size of a myocardial infarct , a part of the damage likely to be prevented.Therefore , we propose that antioxidant reinforcement through vitamins C and E supplementation should protect against the ischemia-reperfusion damage , thus decreasing infarct size.The PREVEC Trial ( Prevention of reperfusion damage associated with percutaneous coronary angioplasty following acute myocardial infarction ) seeks to evaluate whether antioxidant vitamins C and E reduce infarct size in patients subjected to percutaneous coronary angioplasty after AMI .
