• Aims Sympathetic overactivity is one critical factor associated with the development of arterial hypertension, impaired insulin secretion and resistance. Some antihypertensives exert beneficial effects on glucose metabolism, whereas others lead to an impairment of metabolic state with consecutive weight gain. In resistant hypertension, baroreflex activation therapy (BAT) reduces arterial blood pressure (BP) by inhibition of the sympathetic nervous system. The objective of this study was to evaluate whether BAT influences metabolic state in patients with resistant hypertension. Methods Thirty patients with resistant hypertension (10 with known diabetes mellitus) were prospectively included into this study. Blood pressure, BMI, weight, fasting glucose, insulin, C-peptide, hemoglobin A1c, HOMA-IR, HOMA-β, IS QuickI, and glucose levels during oral glucose tolerance test were measured at baseline and 6 months after BAT activation. Results Fasting glucose was significantly reduced after 6 months of BAT, whereas mean 2-h glucose levels during oral glucose tolerance test, fasting insulin levels, C-peptide levels, hemoglobin A1c, HOMA-IR, HOMA-β, IS QuickI , weight, and BMI remained unchanged. Conclusion Despite improvement in fasting glucose, BAT exerts neither sustained additional beneficial effects nor an impairment of metabolic state. Thus, chronic BAT might be an effective interventional method to reduce BP without metabolic disadvantages.
