説明
Inclusion criteria: We plan to include male or female subjects, age 18-80 with a diagnosis of medium-severe sleep apnea syndrome (defined by symptoms, a complaint of excessive daytime sleepiness, an Epworth sleepiness score >8, and an apnea / hypopnea index >15/h) and a resistant hypertension (systolic blood pressure >140 mmHg or >130 mmHg in patients with type II diabetes or chronic kidney disease, under treatment with three antihypertensive drugs including a diuretic).
If the selected patients are treated with CPAP, this therapy should be stable during the whole study time.
Every patient will be asked for a written informed consent.
Exclusion criteria: - Heart failure (normal ejection fractions on echocardiography and no clinical signs and symptoms of heart failure).
- Long acting nitrates, or PDE-5-Hemmer
- Alcohol or drug abuse,
- Malignancy (unless healed or remission > 5 years)
- Disease with systemic inflammation (e.g. rheumatoid arthritis, M. Crohn)
- Pulmonary Hypertension (PAP>50 mmHg)
- Pregnancy
- Anatomical contraindication to renal denervation
- Know allergy to contrast
- Participation in another study within the last month
