Uric acid in heart disease: a new C-reactive protein?

PURPOSE OF REVIEW: To review and interpret the recently published data on hyperuricemia and cardiovascular disease to present an opinion on the nature of link between serum uric acid concentration and the risk for cardiovascular outcomes, and to comment on its implications for clinical practice. RECENT
FINDINGS: Evidence has accumulated in prospective observational studies that link hyperuricemia among younger adults with the risk of subsequent hypertension. Such associations have been observed with respect to insulin resistance, diabetes, and other cardiovascular risk factors. Newer data confirm the link between hyperuricemia and cardiovascular mortality. The use of allopurinol has been shown to be associated with reduced mortality risk in longer term observational studies and with reduced blood pressure in short-term randomized controlled trials. None of these findings is confounded by traditional risk factors.
SUMMARY: The available evidence has established a link between hyperuricemia and cardiovascular disease and this may be causal. Without waiting for the resolution of causality arguments, one can start using serum uric acid concentration as an inexpensive cardiovascular risk marker.
