Renal Sympathetic Denervation for Patients With Chronic Heart Failure
Safety and Effectiveness Study of Percutaneous Catheter-base Renal Sympathetic Denervation for Patients With Chronic Heart Failure

To study whether renal sympathetic denervation(RSD) RSD can slow the progression of CHF and reduce the rate of all-cause mortality effectively and securely.

Chronic heart failure(CHF) as the final stage of various heart diseases is a global and growing public health problem, and its morbidity increases with age. At present, the main therapies for CHF contain drug therapy (including angiotensin-converting enzyme inhibitors, aldosterone antagonist, beta-receptor blockers, diuretic, digoxin etc ) , CRT-D(cardiac resynchronization therapy )/ICD(implantable cardioverter-defibrillator), biological treatment, ultrafiltration dialysis, heart transplantation and so on. Optimize drug therapy is the foundation of CHF, but hypotension and bradycardia limit its indications. ESC(European Society of Cardiology)/AHA(American Heart Association) guidelines recommended CRT-P/D and ICD for drug resistant CHF, but the financial burden limit the use of them and some patients have no response to them. Donors and high costs are considered as two problems which limit heart transplantation appeal. Above all, we are always searching for a new treatment strategy for patients with chronic heart failure. Chronic over-activation of sympathetic nervous system is a major component of heart failure and involves efferent and afferent pathways between brain and many organs. Recently, some studies in animals and humans suggest that activation of both efferent and afferent renal nerves play a crucial role in the pathogenesis and progression of CHF. Activation of renal nerves in CHF may cause a reflex increase in sympathetic tone that contributes to elevated peripheral vascular resistance and vascular remodeling as well as left ventricular remodeling and dysfunction. Recently, many clinical trials have corroborated that catheter-based renal sympathetic denervation (RSD) significantly decreased sympathetic-nerve activity (MSNA) in muscle and whole-body, with a decrease in renal and whole-body norepinephrine spillover. Simultaneously, many clinical researches have also verified that RSD can safely be used to control hypertension, reduce left ventricular hypertrophy, improve glucose tolerance impaired ,decrease proteinuria and sleep apnea severity, which are all recognized as independent risk factors for the development and progression of CHF. Therefore, this randomized parallel control clinical trial was designed to demonstrate whether RSD can slow the progression of CHF and reduce the rate of all-cause mortality effectively and securely.

Primary Purpose: Treatment
Chronic Heart Failure
  • Procedure: RSD
    Contrast renal angiography was performed to localize and assess the renal arteries for accessibility and appropriateness for RSD .once the anatomy was deemed acceptable, the internally irrigated radiofrequency ablation catheter(Celsius Thermocool,Biosense Webster,Diamond Bar,California)was introduced into each renal artery.then was maneuvered within the renal artery to allow energy delivery in a circumferential,longitudinally staggered manner to minimize the chance of renal artery stenosis.About six to nine ablation at 10W for 1 min each were performed in both renal arteries.during ablation, the catheter system monitored tip temperature and impedance,altering radiofrequency energy delivery in response to predetermined algorithm.
    Other Names:
    • renal sympathetic denervation
    • renal denervation
    • renal ablation
  • Other: Conventional therapy
    Optimizing drug therapy,included angiotensin-converting enzyme inhibitors,aldosterone antagonist,beta-receptor blockers,diuretic,digoxin and so on.The patients with chronic heart failure ,whos'condition need for CRT-D(cardiac resynchronization therapy )/ICD(implantable cardioverter-defibrillator),are considered to implant CRT/ICD .CRT is abbreviation for cardiac resynchronization therapy ,ICD is defined for Implantable Cardioverter defibrillator.
  • Active Comparator: RSD+Conventional therapy
    We will recruit 100 randomised CHF patients who meet the inclusion criteria.First undergo renal artery angiography procedure to confirm anatomy.If renal artery meet the inclusion criteria,give the renal sympathetic denervation.At the same time, we will use conventional therapy to protect cardiac function.then we will conduct a clinic follow-up and a telephone follow-up.
    Interventions:
    • Procedure: RSD
    • Other: Conventional therapy
  • Placebo Comparator: Conventional therapy
    We also will recruit 100 randomised CHF patients who meet the inclusion criteria.there are no significant differences in age,gender,race,past medical history,personal history and so on between the two groups.In this group we will use therapy just like the RSD+Conventional therapy group.we will conduct a clinic and a telephone follow-up.
    Intervention: Other: Conventional therapy
