Afterward , the Vitamin-treatment group receives oral doses of vitamins C and E , and the Control group receives placebo for @ days after coronary angioplasty.Primary outcome is infarct size , assessed by cardiac magnetic resonance ( CMR ) , measured @ and @ days after coronary angioplasty.Secondary outcomes are ejection fraction , measured @ and @ days after coronary angioplasty with CMR , and biomarkers for oxidative stress , antioxidant status , heart damage , and inflammation , which will be measured at baseline , at the onset of reperfusion , @ to @ hours after revascularization , and at hospital discharge .
