Left atrial size was estimated with left atrial diameter (LAD), diameter\/height (LAD\/H), and left atrial diameter\/body surface area (LAD\/BSA). The endpoint was one\u2010year recurrent ischemic stroke.

In multivariate COX regression models adjusted for confounders including age, gender, hypertension, diabetes, and history of stroke or transient ischemic attack (TIA), platelet count, fasting blood glucose (FBG), antithrombotic drugs at discharge, stroke volume, and cardiac output, LAD, LAD\/H, and LAD\/BSA all were independent risk factors of recurrent ischemic stroke [LAD: HR 1.065, 95% CI (1.006\u20131.128), <jats:italic>p<\/jats:italic>\u00a0=\u00a0.029; LAD\/H: HR 1.157, 95% CI (1.066\u20131.255), <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.001; LAD\/BSA: HR 1.128, 95% CI (1.059\u20131.202), <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.001].
