Filter by:The aim of this study was to evaluate the therapeutic effect of sodium intake reduction by education in patients with resistant hypertension. The study was designed to maximize the compliance to antihypertensive agents and use optimal doses of antihypertensive agents including diuretics for 2 months before randomization. Patients will be assigned randomly to receiving (1) education of sodium intake reduction and exercise, or (2) education of exercise alone. Education of sodium intake reduction will be blinded to patients, and education of exercise will be provided to both group to blind the subjects. Daytime ambulatory blood pressure is adopted for diagnosis of resistant hypertension to avoid white-coat effect.
The purpose of this study is to document safety and efficacy of renal sympathetic denervation treatment in subjects with uncontrolled hypertension by using Iberis renal denervation system.
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.
The purpose of ALLEGRO-HTN trial is to evaluate the safety and effectiveness of renal denervation in subjects with resistant hypertension by using Allegro renal denervation system
The study was to determine the safe and effective dose of TBC3711 in patients with uncontrolled high blood pressure while already taking blood pressure medications.
