Studies: Renal Denervation May Benefit Certain Heart Patients.
MedPage Today (8/29, Susman) reports, "Renal denervation procedures appear to improve outcomes in patients with advanced heart failure or treatment-resistant arterial hypertension, according to a trio of studies presented...at the European Society of Cardiology (ESC) meeting." Investigators found "in a pilot study," that "heart failure patients who underwent renal denervation with radiofrequency ablation saw an improvement in left ventricular ejection fraction (LVEF) from 25% at baseline to 31% after 12 months (P<0.01), while patients who received standard therapy had minimal and nonsignificant changes from 26% at baseline to 28% at 1 year (P=0.36)." A separate study "found that patients who underwent minimally-invasive catheter-based renal denervation achieved blood pressure (BP) reductions that were in line with the findings in the SIMPLICITY pilot studies." Additionally, researchers reported positive findings from the SIMPLICITY HTN2 Trial.
