ELEVATE-HFpEF is testing a new pacemaker treatment designed specifically for patients with heart failure who have a normal pumping strength (HFpEF). The study compares a personalized dual chamber pacing approach to standard minimal pacing to see if it can improve heart function and symptoms.
Key Objective: The trial is testing whether personalized dual chamber pacing can reduce symptoms and improve quality of life in patients with heart failure with preserved ejection fraction.
Who to Consider: Patients with heart failure with preserved ejection fraction who may be candidates for pacemaker therapy and are interested in potentially improving their heart function should consider enrolling.
Trial Parameters
Brief Summary
ELEVATE-HFpEF is a prospective, randomized, controlled, double-blinded, multi-center, global, interventional pivotal study evaluating the safety and efficacy of dual chamber personalized pacing compared to minimal or no pacing for the treatment of patients with heart failure with preserved ejection fraction (HFpEF).
