Evidence Linking Uric Acid and Hypertension • - An elevated uric acid level consistently predicts the development of hypertension. • - An elevated uric acid level is observed in 25–60% of patients with untreated essential • hypertension and in nearly 90% of adolescents with essential hypertensionof recentonset. • - Raising the uric acid level in rodents results in hypertension with the clinical, hemodynamic, and histologic characteristics of hypertension. • - Reducing the uric acid level with xanthine oxidase inhibitors lowers blood pressure in adolescents with hypertension of recent onset.
