Renal Sympathetic Denervation as Secondary Prevention for Patients After Percutaneous Coronary Intervention. (RSD4CHD2PRE)
November 21, 2012 updated by: Qijun Shan, The First Affiliated Hospital with Nanjing Medical University
Safety and Effectiveness Study of Percutaneous Catheter-based Renal Sympathetic Denervation as a Method of Secondary Prevention for Patients After Percutaneous Coronary Intervention.
To study whether renal sympathetic denervation(RSD) will reduce the all-cause mortality and the recurrence rate of a composite of cardiovascular event(including angina, myocardial infarction, repeat percutaneous coronary intervention and coronary artery bypass grafting) in patients after percutaneous coronary intervention(PCI).
Besides whether RSD can reduce the risk factors for coronary heart disease.

Detailed Description
Coronary heart disease is the leading cause of death worldwide, contributing to over 7.2 million deaths annually.
The main measures of secondary prevention of coronary heart disease are optimizing drug therapy and changing lifestyle.
optimizing drug therapy, including aspirin, beta receptor blockers, lipid regulating drugs (mostly statins, a small part fibrates) and vascular angiotensin-converting enzyme inhibitors.
However, the situation for secondary prevention of coronary heart disease is not satisfying.
EuroASPIRE III survey found that despite effective drug used in the primary or secondary prevention of coronary heart disease, coronary heart disease risk factors, such as high blood glucose,hypertension, high cholesterol and obesity, are still poorly controlled.
At the same time sympathetic activation plays an extremely important role in the development of coronary heart disease, and high sympathetic activity after acute myocardial infarction is closely related to malignant arrhythmia and heart failure.
Recently, many clinical researches have verified that catheter-based renal sympathetic denervation(RSD) can safely be used to substantially reduce blood pressure, reduce left ventricular hypertrophy, improve glucose tolerance and sleep apnea severity.
Simultaneously, a marked reduction in muscle and whole-body sympathetic-nerve activity(MSNA) is apparent, with a decrease in renal and whole-body norepinephrine spillover.
Hypertension, diabetes, high norepinephrine level and obstructive sleep apnea are all recognized as risk factors for the development and recurrence of coronary heart disease.
So, we design this randomized parallel control clinical study to demonstrate whether RSD can reduce the mortality and the recurrence rate of a composite of cardiovascular event in patients after PCI, besides whether RSD can reduce the risk factors for coronary heart disease.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: RSD+PCI+Medicine
We will recruit 300 randomised CHD patients who meet the inclusion criteria.
First undergo percutaneous coronary intervention, and then perform the renal artery angiography procedure to confirm anatomy.
If renal artery meet the inclusion criteria, give the renal sympathetic denervation.
After renal sympathetic denervation traditional secondary prevention of coronary heart disease is recommend.
Finally we will conduct a clinic follow-up every six month and a telephone follow-up every three month(Total 24 months).
|
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(Celcius 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 ablations at 10 W 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 a predetermined algorithm.
Other Names:
Percutaneous coronary intervention (PCI) is a non-surgical procedure used to treat the stenotic coronary arteries of the heart found in CHD.
During PCI, a cardiologist feeds a deflated balloon or other device on a catheter from the inguinal femoral artery or radial artery up through blood vessels until they reach the site of blockage in the heart.
X-ray imaging is used to guide the catheter threading.
At the blockage, the balloon is inflated to open the artery, allowing blood to flow.
A stent is often placed at the site of blockage to permanently open the artery.

Placebo Comparator: PCI+Medicine
We aslo will recruit 300 randomised CHD 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 perform percutaneous coronary intervention firstly, then give traditional secondary prevention of coronary heart disease just like the RSD+PCI+Medicine group.
Third we will conduct a clinic follow-up every six month and a telephone follow-up every three month(Total 24 months).
