PG - 334-8 AB - BACKGROUND: A growing body of evidence supports the pathophysiologic role of oxidative stress and the protective role of naturally occurring antioxidants in congestive heart failure (CHF). Circulating levels of a sensitive and specific marker of lipid peroxidation and levels and activities of a broad spectrum of essential antioxidant micronutrients, vitamins, and enzymes, however, have been never simultaneously evaluated in well-characterized CHF patients. METHODS AND RESULTS: Plasma levels of 8,12-isoprostane F(2alpha)-VI; vitamins A, C, and E; uric acid; and five carotenoids as well as activities of plasma superoxide dismutase and glutathione peroxidase were measured in 30 patients with class II and III New York Heart Association (NYHA) CHF and in 30 controls. Ejection fraction was measured in all patients. Significantly higher 8,12-isoprostane F(2alpha)-VI levels and lower antioxidant levels and activities were found in CHF patients in comparison to controls. Levels of 8,12-isoprostane F(2alpha)-VI were higher in class III than in class II NYHA CHF patients (P=.0012), and inversely correlated with ejection fraction; vitamins A, C, and E; uric acid; carotenoid levels; and superoxide dismutase activity. CONCLUSION: There is an association between increased lipid peroxidation and both antioxidant status and disease severity in CHF in humans. These findings support the rationale for intervention trials aiming at exploring beneficial effects of antioxidant micronutrients in this disease.
