Each participating site will have both an Electrophysiology PI and a Heart Failure PI as co-Principal Investigators, ensuring comprehensive expertise in both AF management and HFpEF care.
We are actively expanding our network. If your institution has expertise in both electrophysiology and heart failure management, we would like to hear from you.
