Relation between serum uric acid and angiographically defined coronary artery disease in postmenopausal women.

Serum uric acid (UA) levels were studied in 40 postmenopausal women and 57 men, almost matched for age and body mass index (BMI) and undergoing coronary angiography. For women, the mean value of UA increased as the number of coronary arteries with > or = 50% stenosis increased. Its value was significantly higher (p < 0.05) in a three-vessel disease group than that of a group without stenosis. No significant changes were seen in men. However, the increase in UA for postmenopausal women was statistically (p < 0.05) correlated with serum triglyceride levels. Possibly, UA is not an independent coronary risk factor. However, elevated UA levels may suggest the prevalence of severe coronary artery stenosis for postmenopausal women.
