Background: Arterial hypertension is the most common comorbidity in patients with heart failure with preserved ejection fraction (HFpEF) and mediates adverse hemodynamics through related aortic stiffness and increased pulsatile load. We aimed to investigate the clinical and hemodynamic implications of renal sympathetic denervation (RDN) in patients with HFpEF and uncontrolled arterial hypertension. Methods: Patients undergoing RDN between 2011 and 2018 in a single-center were retrospectively analyzed and classified as HFpEF (n=99) or no HF (n=65). Stroke volume index and aortic distensibility were measured through cardiac magnetic resonance imaging, and left ventricular (LV) systolic and diastolic properties were assessed echocardiographically. Results: At baseline, patients with HFpEF had higher stroke volume index (median 40 [interquartile range, 33–48] versus 33 [26–40] mL/m 2 , P =0.002), pulse pressure (69 [63–77] versus 61 [55–67] mm Hg, P &lt;0.001), but lower LV-VPES 100mm Hg (18 [10–28] versus 24 [15...
