• ST-segment elevation myocardial infarction
• oxidative stress
• biological antioxidant potential
• diacron-reactive oxygen metabolite

We sought to determine whether serial measurements of oxidative stress levels could serve as a predictive marker for cardiovascular (CV) events in patients with ST-segment elevation myocardial infarction (STEMI). Biological antioxidant potential (BAP) levels were measured at admission and at 6, 12, and 24 months in 69 patients with STEMI. The CV events abruptly increased 6 to 10 months after successful percutaneous coronary intervention in patients with STEMI, and the 6-month BAP levels were significantly lower in patients with CV events (2456 mol/L [interquartile range: 2237-2615 mol/L]) than in those without (2849 mol/L [2575-2987 mol/L], P < .001). A decreased 6-month BAP level was an independent and significant predictor of long-term CV events (hazard ratio = 2.45; 95% confidence intervals 1.10-5.78; P = .04). Our findings suggest that serial changes in antioxidant capacity, assessed by BAP levels, may serve as a predictive marker for CV events after STEMI.
