Testing a nerve procedure for heart failure with normal heart pumping

This study is testing renal denervation—a procedure that blocks certain nerves in your kidneys—as a treatment for a specific type of heart failure called heart failure with preserved ejection fraction (HFpEF). People with HFpEF have hearts that pump normally but don't relax properly, and many also have high blood pressure that doesn't respond well to medicines. Researchers believe this nerve-blocking procedure might help improve symptoms and reduce the strain on your heart.

While doctors have effective treatments for some types of heart failure, HFpEF remains very difficult to treat, and current medicines only manage symptoms rather than address the underlying problem. This trial exists because scientists believe blocking these kidney nerves might help the heart relax better and reduce harmful stress in the body, offering a new hope for patients who haven't benefited enough from standard medications.
