In postmenopausal women, serum uric acid (SUA) levels are associated with coronary endothelial dysfunction (CED) and may also be related to inflammation, a recent study found. In this prospective cohort study SUA, high-sensitivity C-reactive protein levels, and neutrophil count were measured in 229 postmenopausal women (median age 58 years) who underwent diagnostic catheterization. Researchers found:
- CED was diagnosed in 59% of postmenopausal women.
- Mean uric acid level was 4.7±1.3 mg/dL.
- Postmenopausal women with CED had significantly higher SUA compared with patients without CED.
- There was a significant correlation between SUA and percent change in coronary blood flow to acetylcholine.
- SUA levels were significantly associated with increased neutrophil count and high-sensitivity C-reactive protein levels among patients with CED.
