心房颤动性心肌病的研究进展

Research progress in atrial fibrillation-induced cardiomyopathy

心房颤动患者若长期心率控制不佳可引起心脏扩大或心功能受损,甚至心力衰竭,称为心房颤动性心肌病.当心房颤动恢复窦性心律或者严格控制心率,心房颤动性心肌病患者的心脏重构可以逆转.与原发性或其他继发性心肌病合并心房颤动的临床表现容易混淆,因此,及早识别与合理治疗具有重要临床意义.本文就心房颤动性心肌病的定义与分类、流行病学、发生机制、诊断和治疗研究进展进行综述.

Atrial fibrillation with long-term uncontrolled rapid heart rate will result in cardiac enlargement,dysfunction and heart failure,which was defined as atrial fibrillation induced cardiomyopathy.However,the cardiac remodeling can be reversed when sinus rhythm is restored or heart rate is strictly controlled.Compared with other primary or secondary cardiomyopathy with atrial fibrillation,their clinical manifestations are confused easily.Therefore,early identification and reasonable treatment are of great clinical importance.In this paper,the research progress in atrial fibrillation-induced cardiomyopathy will be reviewed.
