Uric acid--a marker for systemic inflammatory response in patients with congestive heart failure?

Congestive heart failure is associated with hyperuricemia and elevations in the levels of circulating markers for inflammation. The purpose of this study was to assess the relationship between levels of serum uric acid, activity of the renin-angiotensin-aldosterone system and TNF-alpha in heart failure patients with respect to the extent of left ventricular dysfunction. Circulating uric acid, TNF-alpha, plasma renin activity and concentrations of aldosterone were measured in 30 patients with congestive heart failure, divided into subgroups according to their NYHA class (II-IV).
