Sympathetic overactivity induces insulin resistance and type 2 diabetes mellitus (T2DM), so it is assumed that denervation might improve glucose metabolism and insulin sensitivity. Some clinical studies have shown that glucose metabolism is improved in patients with resistant hypertension both 1 and 3 months after denervation, and fasting glucose, insulin and C-peptide decreased significantly as did insulin resistance assessed by HOMA-IR. But in some clinical studies, denervation did not lead to a significant improvement of insulin sensitivity ≤12 months after treatment, and no effect in systemic sympathetic activity was observed after denervation. Therefore, the efficacy of denervation on glucose metabolism is still in controversy. The investigators wish to investigate the effect of multi-electrode catheter-based endovascular denervation on glucose metabolism and insulin sensitivity in patients with T2DM.
Sympathetic overactivity induces insulin resistance and type 2 diabetes mellitus (T2DM), so it is assumed that denervation might reduce sympathetic overactivity and improve glucose metabolism and insulin sensitivity. The purpose of this study is to evaluate the effects of multi-electrode catheter-based endovascular denervation on glucose metabolism and insulin sensitivity in patients with T2DM.
