Abstract

Heart failure with preserved ejection fraction (HFpEF) is a complex and heterogeneous clinical syndrome characterized by signs and symptoms of heart failure despite normal or near-normal ejection fraction. It is a debilitating chronic disease that affects millions of people worldwide, and due to the paucity of evidence-based pharmacological treatments for HFpEF, nonpharmacological approaches as potential therapeutic alternatives are of growing interest. As a result, renal denervation (RDN), initially developed as a therapeutic tool for resistant hypertension, has become an area of active clinical interest. RDN is a catheter-based procedure that targets the renal sympathetic pathways, aiming to reduce neurohormonal activation and mitigate maladaptive cardiac remodeling. Preclinical studies in animal models have demonstrated that RDN can improve cardiac and vascular fibrosis, reduce renal inflammation, control hypertension, and alleviate endothelial dysfunction. Recent clinical studies have further highlighted the potential benefits of RDN in patients with HFpEF and uncontrolled hypertension. In this review, we aim to outline the pathophysiology of HFpEF and demonstrate the complex clinical interplay involved in how RDN impacts the heart. Moreover, we discuss the present status of clinical studies on RDN and explore its therapeutic potential as a viable treatment for HFpEF.
