Resistant Hypertension Clinical Trial
1. (RENEWAL-EXERCISE trial) The investigators hypothesize that the increased sympathetic
nervous system activation that is associated with resistant hypertension is a major
contributor in the pathogenesis of exercise diastolic dysfunction and that modulation of
the sympathetic nervous system activity with radiofrequency ablation of the renal artery
sympathetic nerve fibers delivered via a treatment catheter, will have a significant
effect on the diastolic function that is beyond BP-lowering effect.
2. (RENEWAL-REGRESSION trial) The major cause of mortality and morbidity in hypertension is
atherosclerotic cardiovascular disease. the significant decrease in the sympathetic
nervous system activation after renal sympathetic denervation will contribute to
regression over and beyond it's effect of blood pressure reduction.
3. (RENEWAL-PREDICT trial) No data exists regarding the tests or methods predicting the
successful renal denervation causing the effective reduction of BP. For these, the
investigators sought to perform the new tests such as adenosine infusion test during
procedure and skin sympathetic activity measurement before and immediate post-procedure
(detailed explanation provided in section of Methods) and then evaluate the association
between these tests and reduction of BP following procedures.
