Objective: The prognostic value of left atrial (LA) dimensions may differ between patients with and without atrial fibrillation (AF).
Methods: MEDLINE and EMBASE were searched for studies that investigated the association between LA echocardiographic parameters measured by transthoracic echocardiography and cardiovascular outcomes in patients with or without AF. Data were independently abstracted by two reviewers and pooled using random-effects meta-analysis.
