Using tissue-tracking CMR, we measured the LA longitudinal strain and strain rate in each of 12 equal-length segments in two- and four-chamber views. We defined indices of LA mechanical dyssynchrony, including the standard deviation of the time to the peak longitudinal strain (SD-TPS). Patients with a prior history of stroke or TIA (n\u2009=\u200923) had significantly higher SD-TPS than those without (n\u2009=\u2009223) (39.9 vs. 23.4\u2009ms, P\u2009&lt;\u20090.001). Multivariable analysis showed that SD-TPS was associated with stroke\/TIA after adjusting for the CHA2DS2-VASc score, LA minimum index volume, and the peak LA longitudinal strain (P\u2009&lt;\u20090.001). The receiver-operating characteristics curve showed that SD-TPS identified patients with stroke\/TIA more accurately than CHA2DS2-VASc score alone (c-statistics: 0.82 vs. 0.75, P\u2009&lt;\u20090.001).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Higher mechanical dyssynchrony of the LA during sinus rhythm is associated with a history of stroke\/TIA in patients with AF.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ehjci\/jex156","type":"journal-article","created":{"date-parts":[[2017,5,19]],"date-time":"2017-05-19T15:09:56Z","timestamp":1495206596000},"page":"433-441","source":"Crossref","is-referenced-by-count":25,"title":["Mechanical dyssynchrony of the left atrium during sinus rhythm is associated with history of stroke in patients with atrial fibrillation"],"prefix":"10.1093","volume":"19","author":[{"given":"Luisa","family":"Ciuffo","sequence":"first","affiliation":[{"name":"Division of Cardiology, Cardiac Arrhythmia Service, Johns Hopkins University School of Medicine, 600 N.
