One possible path to address pathological wave reflections is reducing sympathetic overactivity via renal denervation (RDN) with the aim to enhance arterial compliance. We sought to non-invasively quantify pulse wave reflections changes in patients undergoing RDN.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Patients who underwent RDN for resistant hypertension were classified as patients with HFpEF and patients without heart failure, the latter of which served as the control group. Pulse wave analysis (PWA) was assessed using a piezoelectric device, and reflection magnitude was quantified by the augmentation index (AIx), and timing by backward transit time (BTT) before and 3\u00a0months after RDN. Ambulatory blood pressure was assessed at baseline and after 3\u00a0months to adjust for blood pressure changes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Of 51 patients, 22 had HFpEF, and 29 served as controls. While baseline values in AIx and BTT were not different between HFpEF and control patients, RDN was associated with a significant decrease in AIx by 5.6% (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.04) and a significant prolongation of BTT by 17.8\u00a0ms (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.007) in patients with HFpEF.
