摘要

Hyperuricemia (HU) is a well recognized risk factor for cardiovascular diseases. Intima-media thickness (IMT) of the carotid artery noninvasive assessed by ultrasonography is now validated as a sensitive marker for atherosclerosis and it is directly associated with increased risk of cardiovascular disease. The aim of this study was to evaluate the correlations between IMT and uric acid levels in patients with hypertension (HT). Our study consisted of a group of 30 patients with HT without HU (male 58%, mean age ± S.D.: 49 ± 10 years), a group of 25 patients with HT and HU (male 52%, mean age ± S.D: 52 ± 10 years), and a control group of 25 healthy subjects (male 55%, mean age ± S.D: 50 ± 11 years). All patients in the study groups were examined by high resolution B-mode ultrasound to measure the IMT of the common carotid artery. IMT values were significantly higher in the hypertensive patients groups with and without HU, compared to the control group (0.98 ± 0.28 mm, 1.41 ± 0.31 mm versus 0.56 ± 0.15 mm, respectively, p < 0.001). All patients with HU had significantly higher carotid IMT compared to the patients without HU. In this study we have shown that higher serum uric acid levels are associated with atherogenesis independent from hypertension.
