Multivariate model 1 includes age, female sex, diastolic BP, sup MCA stroke, NIHSS and AC. Multivariate model 2 includes age, female sex, diastolic BP, sup MCA stroke, NIHSS and LAVI>34 mL/m2.
AC, atrial cardiomyopathy as defined in ARCADIA; BP, blood pressure; LAVI, indexed left atrial volume; MCA, middle cerebral artery; NIHSS, National Institute of Health Stroke Scale.
