BACKGROUND: Increased oxidative stress, a common feature in chronic heart failure, has been associated with inflammation, endothelial dysfunction, and extracellular matrix degradation. Statins have known anti-inflammatory and anti-oxidant effects; however, their role in chronic heart failure is still controversial. METHODS: This was a prospective study of 38 patients with stable systolic chronic heart failure. Patients received a 4-week placebo course, followed by atorvastatin 20 mg/day for 8 weeks. Oxidative stress, inflammation and remodeling markers, brachial artery flow-mediated vasodilation, and 6-minute walk test were evaluated at baseline, 4, and 8 weeks. RESULTS: Mean age was 58 +/- 12. Mean left ventricular ejection fraction was 27% +/- 12%. No significant differences were observed between measurements at baseline and after placebo. Atorvastatin induced a significant decrease of matrix metalloproteinase-9 activity, high-sensitivity C-reactive protein, tumor necrosis factor-alpha, interleukin-6, and malondialdehyde, and a significant increase of endothelial superoxide dismutase activity when compared with placebo. No differences in tissue inhibitor of matrix metalloproteinase and matrix metalloproteinase-2 activities were observed. Atorvastatin use was associated with an improved flow-dependent brachial vasodilation and exercise capacity in the 6-minute walk test. CONCLUSIONS: In chronic heart failure patients, atorvastatin therapy is associated with a decrease of inflammation and extracellular matrix remodeling, improving both endothelial function and exercise capacity.
