摘要Atrial fibrillation(AF)is the most common sustained cardiac arrhythmia,significantly impacting patients'qual-ity of life and increasing the risk of death,stroke,heart failure,and dementia.Over the past two decades,there have been signific-ant breakthroughs in AF risk prediction and screening,stroke prevention,rhythm control,catheter ablation,and integrated man-agement.During this period,the scale,quality,and experience of AF management in China have greatly improved,providing a solid foundation for the development of guidelines for the diagnosis and management of AF.To further promote standardized AF management,and apply new technologies and concepts to clinical practice in a timely and comprehensive manner,the Chinese Society of Cardiology of the Chinese Medical Association and the Heart Rhythm Committee of the Chinese Society of Biomedical Engineering have jointly developed the Chinese Guidelines for the Diagnosis and Management of Atrial Fibrillation.The guidelines have comprehensively elaborated on various aspects of AF management and proposed the CHA2DS2-VASc-60 stroke risk score based on the characteristics of AF in the Asian population.The guidelines have also reevaluated the clinical ap-plication of AF screening,emphasized the significance of early rhythm control,and highlighted the central role of catheter abla-tion in rhythm control.
