[Renal denervation a new treatment option in resistant arterial hypertension].

Resistant hypertension is defined as blood pressure that remains above therapeutic goal despite the use of 3 antihypertensive drugs including a diuretic. After exclusion of secondary causes and medical in compliance, the estimated prevalence of resistant arterial hypertension ranges from 4% to 19% in hypertensive patients. Treatment requires a multimodal therapeutic approach. Hyperactivation of the sympathetic nervous system plays a key role in the genesis of hypertension. Targeting renal sympathetic nerves, percutaneous catheter-based renal denervation is a new therapeutic option for the treatment of resistant arterial hypertension in selected drug resistant patients.
