Catheter-guided renal sympathetic denervation in patients with therapy-refractory hypertension

Hypertension is the leading cause of cardiovascular disease worldwide, with a prevalence of 30–40% in the West and 20–35% in the Middle East. More than50% of patients have inadequate blood pressure control despite combined antihypertensive medication. Reasons for the failure to achieve recommended blood pressure values include lack of patient compliance and inefficiency of antihypertensive treatment (therapy-refractory hypertension).
