Outcomes
Primary Outcome Measures
Change in insulin resistance from baseline to 3 months after renal denervation
To determine the effects of renal sympathetic denervation on insulin resistance (determined by the Homeostasis Model Assessment - Insulin Resistance method) at 3 months after renal denervation
Change in muscle sympathetic nerve activity (MSNA) from baseline to 3 months after renal denervation
To determine the effects of renal sympathetic denervation on MSNA at 3 months after renal denervation
Secondary Outcome Measures
Change in insulin resistance from baseline to 12 months after renal denervation
To determine the effects of renal sympathetic denervation on insulin resistance long-term (12 months after renal denervation).
Change in muscle sympathetic nerve activity (MSNA) from baseline to 12 months after renal denervation
To determine the effects of renal sympathetic denervation on MSNA long-term (12 months after renal denervation).
