About Atrial Fibrillation
Atrial fibrillation (AFib) is the most common type of heart arrhythmia, causing an irregular and often rapid heartbeat. It significantly increases the risk of stroke, heart failure, and other complications. Treatment includes blood thinners, heart rate or rhythm control medications, and procedures like ablation.
Clinical trials are advancing new treatments for atrial fibrillation. Currently, 27 studies are recruiting a combined 16,100 participants across the United States. Research is being conducted by 24 organizations including Johns Hopkins University, Icahn School of Medicine at Mount Sinai, Population Health Research Institute and 21 others.

As of March 2026, the atrial fibrillation clinical trial landscape includes 27 actively recruiting studies across 87 cities in the United States. These studies are collectively seeking 16,100 participants, with an average enrollment target of 596 per study.
Research is being led by 24 different organizations, including Johns Hopkins University, Icahn School of Medicine at Mount Sinai, Population Health Research Institute, Anthos Therapeutics, Inc., Eli Lilly and Company, and 19 others.
