Atrial fibrillation AF is a major cause of heart-related illness and death, especially among Asian patients who face higher risks of serious bleeding such as brain hemorrhage compared to non-Asians. This research, called the COhort of antithrOmbotic use and cLinical outcomes in patients with Atrial Fibrillation COOL-AF Phase 2, aims to study how antithrombotic medication use changes over time and how these changes affect health outcomes in people with AF. The study is observational and conducted across multiple centers in Thailand. Participants in this study have known or newly diagnosed non-valvular AF and are followed without any intervention or treatment assigned by the study. The study plans to enroll about 3680 patients over two years from 33 centers. Participants will be monitored every 6 months for up to 3 years to observe patterns of medication use, particularly warfarin and non-vitamin K antagonist oral anticoagulants NOACs, and clinical events including stroke, systemic embolism, bleeding, heart attacks, and heart failure. Throughout the study, patients will have regular check-ins every six months to track their medication usage and health status. Researchers will collect data on important outcomes such as rates of stroke, bleeding events, and quality of life. The studys primary focus is on long-term safety and effectiveness of antithrombotic treatments in this population. The total participation duration can be up to 3 years, ensuring thorough observation of clinical outcomes and treatment patterns.
