The RESPLASH Study

The investigators propose a multicenter, prospective, single blind, randomized controlled pilot study. Patients with treatment-resistant hypertension and diabetes mellitus type 2 will be enrolled to undergo renal artery denervation with subsequent splanchnic nerves denervation for lowering blood pressure and glycemic levels. 20 patients will be randomly selected from outpatient cardiology clinics and will be assigned (1:1) to receive an FDA approved catheter-based denervation (CDN) of the renal arteries or CDN of the renal arteries with subsequent CDN of the splanchnic nerves at the level of the celiac artery and SMA. All patients will receive non-selective renal and mesenteric artery angiography prior and post CDN. All patients will undergo office systolic and diastolic blood pressure measurements, glycemic indices (HbA1c, fasting plasma insulin, C-peptide), and other laboratory assessments (plasma norepinephrine, renin, aldosterone, angiotensin II, lipids, and liver biochemistry) at baseline and outpatient follow-up visits (months 1, 3 and 6 post procedure).
