Key result
Hyperuricemia was independently associated with a significantly higher risk of elevated cardio-ankle vascular index in Chinese females (OR 3.65), but this association was not observed in males.

Elevated serum uric acid is independently associated with increased arterial stiffness in Chinese women, but not in men, suggesting a gender-specific cardiovascular risk profile.
Hyperuricemia was associated with higher CAVI in Chinese females but not males; leaves open gender-specific CV risk stratification.
BACKGROUND: Little is known about the relationship between serum uric acid (SUA) and cardio-ankle vascular index (CAVI) in Chinese population. Therefore, we aimed to investigate the gender difference in the association of SUA and CAVI in a southwestern Chinese population. METHODS: Data were obtained from subjects via routine physical examinations in the Public Health Center of our hospital between 2011 and 2014 in Chongqing. The data included completed anthropometry and blood biochemical indicators. The CAVI were recorded using an automatically VaseraVS-1000 vascular screening system. RESULTS: We found females with hyperuricemia (HUA) had significantly higher CAVI than women with normal SUA (8.45 ± 1.40 vs 7.67 ± 1.15, P<0.05). Then we defined high CAVI as CAVI≥9 m/s, and compared the percentage of high CAVI, we found women with HUA had higher percentage of high CAVI than women with normal SUA (26.83% vs 9.38%, P<0.05). Those differences were not significant in males. Also, the logistic regression analysis found age and hypertension were major independent risk factors associated with high CAVI in both genders. HUA and hyperglycemia were independently associated with high CAVI in females with an OR of 3.65, 95%CI (1.37-9.73) and 3.02, 95%CI (1.38-6.63) respectively. However, these significant associations were not be found in males. CONCLUSIONS: Our data showed positive associations between elevated SUA levels and higher CAVI risk in the inland Chinese females, but not in males. The reason for the gender differences were still unclear, sex hormones may play a role. Further prospective studies including detailed personal information and multicenter were required.

Zheng et al. (2018) conducted a cross-sectional in Healthy adults (routine health examination) (n=1,217). Hyperuricemia vs. Normal serum uric acid was evaluated on High cardio-ankle vascular index (CAVI ≥ 9 m/s) in females (OR 3.65, 95% CI 1.37-9.73, p=<0.05). Hyperuricemia was independently associated with a significantly higher risk of elevated cardio-ankle vascular index in Chinese females (OR 3.65), but this association was not observed in males.
