Methods: To divide 102 patients with elderly hypertensive into 3 groups according to the difference of blood pressure result, and compare the relationship between serum uric acid and blood pressure among the different groups. They were divided into normal group、intimae tricking group、plaque shaping group and vascular stenosis group accoraing to ultrasound result. To compare the serum uric acid level and blood pressure among each group.
