Echocardiography (echo) is commonly performed poststroke and may help identify candidates for prolonged rhythm monitoring. The PER DIEM trial randomized poststroke patients without known AF to 12\u2010months of implantable loop recorder (ILR) monitoring versus 30\u2010days of external rhythm monitoring and demonstrated higher AF detection rates using ILR.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Aims<\/jats:title>\n                    <jats:p>This substudy of the PER DIEM trial investigated the association between baseline echo parameters and poststroke AF detection.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>PER DIEM trial participants with complete transthoracic echo performed at the time of ischemic stroke were included.

AF patients were significantly older and had higher CHA2DS2\u2010VASc scores. Patients with AF had higher left atrial volume index (LAVI), lower absolute left ventricular global longitudinal strain (LV GLS) and lower contractile LA strain compared to those without AF. Univariate analysis showed that a higher LAVI (OR 1.30 per 5\u00a0mL\/m2 increase, 95%CI 1.03\u20131.64,\n                      <jats:italic>p<\/jats:italic>\n                      = 0.025) and lower absolute LV GLS (OR 2.73 per 5% decrease, 95%CI 1.37\u20136.04,\n                      <jats:italic>p<\/jats:italic>\n                      = 0.007) were significantly associated with poststroke AF, with optimal cutoff values of 32.12\u00a0mL\/m2 and 15.5%, respectively.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In patients with ischemic stroke, LAVI and LV GLS were significantly associated with subsequent AF detection.
