Renal Denervation in Patients With Chronic Heart Failure and Resynchronization Therapy

December 29, 2014 updated by: Aleksander Kusiak, Jagiellonian University
Chronic heart failure is becoming more and more common disease and activation of sympathetic nervous system plays a crucial role in its development. There is some data allowing to suspect that one of the new treatment methods- renal denervation, also in patients with chronic heart failure may lead to decrease of systemic activity sympathetic nervous system and, as a consequence, to decrease of disease progression. The research hypothesis is whether renal denervation in case of symptomatic heart failure, even the optimal treatment therapy is used (including resynchronization therapy), is contributing to the improvement in parameters of neurohormonal activation, hemodynamics and clinical patient status. The aim of the study is to obtain a new knowledge concerning renal denervation in chronic heart failure, So far only very limited data- mostly case reports- are available in this study area.
