A Phase 4, Randomized, Open Label, Multicenter Prospective Comparative Study To Evaluate The Treatment Of Atrial Fibrillation In Preserved Cardiac Function Heart Failure
Electrophysiology Research Foundation
Summary
Heart failure (HF) with preserved left ventricular function (pEF) is difficult clinical syndrome to treat effectively with few evidence based therapies. Atrial fibrillation (AF) is now an important co-morbidity being observed in 43% of patients with HFpEF. Rhythm control has not been studied in this population. Catheter ablation and antiarrhythmic drugs are rhythm control therapies that have been used for treatment of AF without HF or HF with reduced systolic function but have not been widely applied in HFpEF. No controlled comparative evaluation has been performed in HFpEF. The introduction of wireless pulmonary artery hemodynamic monitoring has permitted optimization of HF therapy in patients with chronic HF with reduced and preserved EF. Reduction in HF hospitalizations has been observed in post hoc analyses of HFpEF patients but has not been systematically applied in AF patients with HFpEF. In this study, we propose to study both rhythm control and optimized HF therapeutic approaches in an AF with HFpEF study population in a pilot study using a sequential two phase randomized controlled clinical trial design.
Description
This is a prospective pilot study utilizing a randomized comparative sequential evaluation of these two therapeutic approaches in two consecutive phases: Phase 1 will examine an initial catheter ablation strategy versus an initial antiarrhythmic drug (AAD) therapy strategy for safety and efficacy in patients with atrial fibrillation with preserved systolic cardiac function, heart failure hospitalization in the past year or one or more documented HF events. Phase 2 will examine optimized rhythm control therapy with and without wireless pulmonary artery pressure hemodynamic monitoring for HF t…
