Renal Sympathetic-Nerve Ablation for Uncontrolled Hypertension

Abstract: To the Editor: The renal sympathetic nerves have been identified as a major contributor to the complex pathophysiology of hypertension in both experimental models and in humans.1 Patients with essential hypertension generally have increased efferent sympathetic drive to the kidneys, as evidenced by elevated rates of renal norepinephrine spillover, defined as the amount of transmitter that escapes neuronal uptake and local metabolism and thus “spills over” into the circulation. Hypertension is also characterized by an increased rate of sympathetic-nerve firing, possibly modulated by afferent signaling from renal sensory nerves.2–4 A 59-year-old male patient with long-standing essential hypertension that was . . .

Effect of Renal Sympathetic Denervation on Glucose Metabolism in Patients With Resistant Hypertension A Pilot Study

Abstract: Background—Hypertension is associated with impaired glucose metabolism and insulin resistance. Chronic activation of the sympathetic nervous system may contribute to either condition. We investigated the effect of catheter-based renal sympathetic denervation on glucose metabolism and blood pressure control in patients with resistant hypertension. Methods and Results—We enrolled 50 patients with therapy-resistant hypertension. Thirty-seven patients underwent bilateral catheter-based renal denervation, and 13 patients were assigned to a control group. Systolic and diastolic blood pressures, fasting glucose, insulin, C peptide, hemoglobin A1c, calculated insulin sensitivity (homeostasis model assessment–insulin resistance), and glucose levels during oral glucose tolerance test were measured before and 1 and 3 months after treatment. Mean office blood pressure at baseline was 178/963/2 mm Hg. At 1 and 3 months, office blood pressure was reduced by 28/10 mm Hg (P0.001) and 32/12 mm Hg (P0.001), respectively, in the treatment group, without changes in concurrent antihypertensive treatment. Three months after renal denervation, fasting glucose was reduced from 1183.4 to 1083.8 mg/dL (P0.039). Insulin levels were decreased from 20.83.0 to 9.32.5 IU/mL (P0.006) and C-peptide levels from 5.30.6 to 3.00.9 ng/mL (P0.002). After 3 months, homeostasis model assessment–insulin resistance decreased from 6.00.9 to 2.40.8 (P0.001). Additionally, mean 2-hour glucose levels during oral glucose tolerance test were reduced significantly by 27 mg/dL (P0.012). There were no significant changes in blood pressure or metabolic markers in the control group. Conclusions—Renal denervation improves glucose metabolism and insulin sensitivity in addition to a significantly reducing blood pressure. However, this improvement appeared to be unrelated to changes in drug treatment. This novel procedure may therefore provide protection in patients with resistant hypertension and metabolic disorders at high cardiovascular risk.
