About

Many studies have studied the effect and safety of renal denervation. However, it remains unknown what the exact mechanism behind renal denervation is. It can be hypothesized that a difference in renal blood flow occurs after treatment. In the light of this ignorance, current study will investigate whether renal denervation leads to a difference in renal blood flow after treatment with renal denervation.

Enrollment: 15 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Individual is scheduled to undergo renal denervation as standard patient care for resistant hypertension.
• Individual is diagnosed with resistant hypertension. Secondary causes and a white coat hypertension are actively excluded.
• Individual is ≥18 years of age.
• Individual agrees to have all study procedures performed, and is competent and willing to provide written informed consent to participate in this clinical study.

Exclusion criteria

• Individual is excluded from treatment with pRDN .
• Individual has an estimated glomerular filtration rate (eGFR) of <30mL/min/1.73m2, using the MDRD calculation.
• Individual has experienced a myocardial infarction, unstable angina pectoris, or a cerebrovascular accident within 6 months of the screening visit, or has widespread atherosclerosis, with documented intravascular thrombosis or unstable plaques.
• Individual has any serious medical condition, which in the opinion of the investigator, may adversely affect the safety and/or effectiveness of the participant or the study (i.e., patients with clinically significant peripheral vascular disease, abdominal aortic aneurysm, bleeding disorders such as thrombocytopenia, haemophilia or significant anaemia).
• Individual is pregnant, nursing or planning to be pregnant.
• Individual has a known, unresolved history of drug use or alcohol dependency, lacks the ability to comprehend or follow instructions, or would be unlikely or unable to comply with study follow-up requirements.
