The guidelines for the management of atrial fibrillation (AF) are developed by the European Society of Cardiology (ESC) Task Force for the Management of Atrial Fibrillation, with contributions from the European Heart Rhythm Association (EHRA). The guidelines are endorsed by the European Association for Cardio-Thoracic Surgery (EACTS) and are intended for personal and educational use, with no commercial use authorized. The guidelines cover the epidemiology, mechanisms, detection, natural history, and acute management of AF, as well as long-term management strategies including antithrombotic therapy, rate and rhythm control, and upstream therapies. They emphasize the importance of early detection and prevention of AF-related complications, such as stroke, and highlight the role of non-pharmacological interventions and ablation techniques. The guidelines also address specific populations, such as those with heart failure, athletes, valvular heart disease, and diabetes mellitus. The document is based on a comprehensive review of published evidence and aims to assist healthcare professionals in making informed decisions for individual patients.The guidelines for the management of atrial fibrillation (AF) are developed by the European Society of Cardiology (ESC) Task Force for the Management of Atrial Fibrillation, with contributions from the European Heart Rhythm Association (EHRA).
