Introduction Resistant hypertension (RH) is directly related to increased mortality, severe renal changes, and cardiac and cerebrovascular diseases, due to lack of adequate drug treatment. Cardiovascular disease mortality increases progressively and linearly as BP increases, whereas BP lowering is associated with significantly reduced risks. – Increased sympathetic tone in renal arteries is one of the major components of RH, and catheters have been developed using several technologies which allow for radiofrequency ablation (RA) and blood pressure (BP) reduction. The discussions […]
