Although both left atrial (LA) and ventricular (LV) dysfunction has been accepted as an important risk factor of atrial fibrillation (AF), usefulness of LA and LV strain has not been fully compared for prediction of AF. The aims of this study were to clarify the associations of both LA and LV strain with AF and to compare their predictive values in the risk stratification for AF.

超声心动图对房颤风险的分层：左心房和心室应变的比较

尽管左心房（LA）和心室（LV）功能障碍均被认为是房颤（AF）的重要危险因素，但尚未完全比较LA和LV应变对预测AF的有用性。这项研究的目的是阐明LA和LV菌株与AF的关联，并比较其在AF危险分层中的预测值。
