简要总结

The purpose of this study is to discover whether the inhibition of the xanthine oxidase with allopurinol leads to a reduction of the production of oxygen free radicals in patients with CHF and thereby improves characteristics of oxydative metabolism, peripheral blood flow, immune function and functional status.
