Eligibility Criteria
You may qualify if:
- Age of participants will be 18-75 years.
- Treatment-resistant hypertensive subjects on medical management.
- Office systolic blood pressure (oBP) ≥ 160mmHg.
- Daytime mean ambulatory BP (ABPM) ≥ 140 mmHg.
- Persistent hypertension on at least three anti-hypertensive medications, including a diuretic, at stable, maximum tolerated dose within the last 90 days.
- No evidence for causes of secondary HTN (hypertension ) following thorough clinical assessment.
- At least one carotid body detected in CT angiography of the neck, defined as an hyper-enhanced ovoid structure strongly located poster-medially from the area of carotid bifurcation.
- Ability to give and giving informed consent to participate in the study.
- Women of child-bearing potential have a negative pregnancy test.
You may not qualify if:
- Calculated GFR (glomerular filtration rate) \< 30ml/min/m2
- Obstructive carotid atherosclerotic disease which precludes safe delivery of ablation catheter or performance of ablation
- Must be at least 6 months post renal denervation therapy.
- Oxygen saturation at rest below 92%.
- Requirement for oxygen therapy to maintain oxygen saturation.
- Severe untreated obstructive sleep apnea (defined as an apnea-hypopnea index (AHI) ≥ 30/hour during Polysomnography associated with an average minimum oxygen desaturation of \< 85%.
- Patients wish to participate in mountain climbing, sky diving or free diving.
- Pregnancy or anticipation of pregnancy.
- Acute coronary syndrome or unstable angina \< 6 months before scheduled procedure.
- History of repeated episodes of hypoglycemia with hypoglycemic unawareness.
- Known diabetic autonomic neuropathy.
- History of, or current atrial fibrillation (AF).
- Life expectancy of less than 24 months due to other disease.
- Intravenous or inhaled recreational drug use.
- Excessive use of alcohol or sedatives (alcohol intake \> 28 units/week).
- +18 more criteria
