Inflammation: a possible mechanism for a causative role of hyperuricemia/gout in cardiovascular disease

Abstract

Hyperuricemia and gout are independent risk factors associated with the development of hypertension, metabolic syndrome, vascular damage, and renal disease. Whether these risk factors are causally related to these important chronic co-morbidities remains uncertain, but inflammation may provide a mechanistic explanation. Hyperuricemia and gout negatively affect vascular function by exerting pro-oxidant effects and by decreasing nitric oxide bioavailability, thus inducing inflammation and endothelial dysfunction, which may promote hypertension, metabolic syndrome, and cardiovascular (CV) disease. This paper presents and discusses current understanding of the diverse influences promoting hyperuricemia and gout and the basis of acute and chronic hyperuricemia/gout-related inflammation. This review is based on a PubMed/Embase database search for articles on hyperuricemia and its impact on cardiovascular and renal function.
