Clinical Trial Summary

Heart failure with preserved ejection fraction has a high mortality, which is contrasted by a total absence of therapy options besides symptomatic diuretic treatment. This study aims to explore the potential of renal denervation as a treatment option for heart failure with preserved ejection fraction.

Clinical Trial Description

Heart failure is one of the most important diseases worldwide, with a 5-year mortality of up to 75% in symptomatic patients. While substantial progress has been made in the treatment of patients with reduced left ventricular ejection fraction (HFrEF), mortality for patients with heart failure and preserved ejection fraction (HFpEF) remains unchanged, despite a comparable prevalence and mortality of the disease as for heart failure with reduced ejection fraction. HFpEF is a heterogeneous condition and has been a diagnostic and therapeutic challenge for clinicians and researchers over the past decades. While some rare cases of HFpEF can be attributed to specific diseases like amyloidosis, in most other patients common characteristics are increased ventricular filling pressures and ventricular and arterial stiffening as frequently caused by ageing, diabetes and arterial hypertension. Furthermore, increased sympathetic activity has been described as one pathogenic contributor to chronic heart failure and is associated with poor clinical prognosis. It also leads to a more pulsatile BP profile which can cause a mismatch in arterio-ventricular coupling. The modulating effects on the sympathetic nervous system induced by renal denervation (RDN) should be beneficial in HFpEF, as they improve resting and exercise hemodynamics due to an improved ventriculoarterial coupling by reduced aortic stiffness and lower systemic blood pressure. In addition, RDN leads to optimized stroke volume and stroke work and might affect cardiac preload by improving blood distribution into the splanchnic compartment. This study aims to explore the potential of RDN as a therapy for HFpEF in a single center pilot trial using a randomized, sham-controlled double-blind design. ;
