Renal Sympathetic Denervation in Patients With Hypertension and Paroxysmal Atrial Fibrillation — RSDforPAF  

Hypertension Clinical Trial

Official title:
Safety and Effectiveness Study of Percutaneous Catheter-based Sympathetic Denervation of the Renal Arteries in Patients With Hypertension and Paroxysmal Atrial Fibrillation

Clinical Trial Summary

The purpose of this study is to demonstrate whether renal sympathetic denervation is safe and effective in patients with hypertension and paroxysmal atrial fibrillation.

Clinical Trial Description

Atrial fibrillation (AF) is one of the most common cardiac arrhythmia, complications of AF such as stroke, thromboembolism and heart failure will bring high disable rate and mortality , which will be serious influence on people's health and aggrandize medical financial burden, however, treatment for AF is not ideal. The affection of traditional antiarrhythmia drugs is not enough good, due to extra-heart bad reaction and potential arrhythmogenic substrate function restricted; rate control strategy applied quite abroad, however, anticoagulated medicine were not applied enough, Radiofrequency catheter ablation of AF has developed rapidly in recent years, But it's station is also disputed and its success rate is low and recrudescence is very high. meanwhile, serious complications will be caused. So far, hypertension is the most risk factor of AF. Long-term hypertension will change left-ventricle structure, through variability of pressure loading and capacity loading, damage diastolic function of left-ventricle. Increase of diastolic pressure in left-ventricle and atrial pressure will gradually result in atrial enlargement and fibrosis, so it will cause atrial fibrillation, repeating paroxysm or slow maintaining. Investigation indicated anti-hypertension therapy can decrease occurrence ratio and reoccurrence ratio of AF. Recently, many clinical researches have verified that renal sympathetic denervation acquired exact and sustained hypotension effect, In addition, Renal sympathetic denervation can reduce left ventricular hypertrophy, improve glucose metabolization and obstructive sleep, meanwhile, it reduce the level of nonepinephrine for both partial and whole-body. While left ventricle hypertrophy, left atrium enlarge，epinephrine over release itself and breath sleep obstacle are the independent dangerous factors of emerging AF. So ,we design this randomized parallel control multi center clinical study to demonstrate that renal sympathetic denervation is a safe and effective treatment for patients with hypertension and paroxysmal atrial fibrillation. ;
