We analyzed soluble vascular adhesion molecules ((s)VCAM-1), reactive oxygen metabolites (ROMs) level, total antioxidant status (TAS) and telediastolic left ventricular volume (TLVV) in patients with myocardial infarction undergoing reperfusion therapy and treated with antioxidant vitamins (AT) or placebo (P) before and for 1 month after reperfusion. After reperfusion, sVCAM-1 serum concentration, reactive oxygen metabolites level, and TLVV were significantly higher in patients treated with placebo than in those treated with antioxidant vitamins, while TAS was significantly higher in patients treated with antioxidant supplementation. We observed that 48 hours after reperfusion sVCAM-1 (P) vs sVCAM-1(AT) was 2.030 +/- 0.5 vs 1.63 +/- 0.7 mu g/ml with p<0.01; ROMs (P) vs ROMs (AT) were 335.60 +/- 35.80 vs 307.5 +/- 47.10 U.CARR with p<0.05; TAS (P) vs TAS (AT) was 526.47 +/- 44.24 vs 737.65 +/- 51.15 mu mol/l with p<0.01; 1 week after reperfusion TLVV (P) vs TLVV (AT) was 125.12 +/- 29.80 vs 119.40 +/- 29.40 ml with p<0.05; 1 month after reperfusion TLVV (P) vs TLVV (AV) was 132.00 +/- 33.50 vs 123.40 +/- 21.60 ml with p<0.05. In the first period after infarction, vitamin treatment improves the antioxidant system and reduces oxidative stress, inflammatory process and left ventricular remodeling.
