Serum uric acid concentration as a risk factor for cardiovascular mortality: a longterm cohort study of atomic bomb survivors.J Rheumatol. 2005 May; 32(5):906-12.JR
To elucidate the association of serum uric acid concentration with cardiovascular mortality risk.
Serum uric acid level measured from 1966 through 1970 in 10,615 Japanese individuals from a cohort of atomic bomb survivors was analyzed for association with subsequent cardiovascular and all-cause mortality until 1999 using the Cox proportional hazard model.
During an average followup of 24.9 years, 5225 deaths occurred, of which 1984 were ascribed to cardiovascular disease. In men, after adjustment for age, elevated serum uric acid level was associated with both cardiovascular and all-cause mortality. After additional adjustment for potential cardiovascular disease risk factors including body mass index, smoking status, alcohol consumption, systolic blood pressure, cholesterol level, and histories of hypertension, diabetes and cardiovascular disease, elevated serum uric acid level in men was associated with all-cause mortality but not with cardiovascular mortality. In women, even after these adjustments, elevated serum uric acid level was significantly associated with cardiovascular and all-cause mortality.
Increased serum uric acid level is a significant and independent risk factor for cardiovascular mortality in women and for all-cause mortality in both men and women.
