This study aimed to identify echocardiographic predictors of POAF to improve risk stratification. A total of 131 patients undergoing cardiac surgery were analyzed and divided into two groups based on POAF occurrence. Echocardiographic analysis showed that patients with POAF had larger left and right atrial dimensions and impaired atrial function. Prolonged total atrial conduction time (TACT), reduced atrial emptying volumes, and contractile function were more common in the POAF group. Univariable analysis identified LAEF (\u03c72 = 71.8, p &lt; 0.001), LAKE (\u03c72 = 70.1, p &lt; 0.001), RATEF (\u03c72 = 65.7, p &lt; 0.001), and RAAEF (\u03c72 = 66.8, p &lt; 0.001) as significant predictors of POAF, each with an area under the curve (AUC) greater than 0.89. In multivariable analysis, LAKE (OR = 0.27, p &lt; 0.001), hypertension (OR = 11.87, p = 0.035), left ventricular ejection fraction (OR = 1.08, p = 0.020), and peripheral vascular disease (OR = 40.28, p = 0.002) were independent predictors. The final model showed a significant discriminatory ability (AUC = 0.94). LAKE and clinical factors remained independent predictors after adjustment.<\/jats:p>","DOI":"10.3390\/jcdd12040160","type":"journal-article","created":{"date-parts":[[2025,4,17]],"date-time":"2025-04-17T20:05:56Z","timestamp":1744920356000},"page":"160","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Echocardiographic Predictors of Postoperative Atrial Fibrillation After Cardiac Surgery: Assessing Atrial Mechanics for Risk Stratification"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8690-4921","authenticated-orcid":false,"given":"Velimir","family":"Peri\u0107","sequence":"first","affiliation":[{"name":"Clinic for Cardiac Surgery, University Clinical Center Nis, 18000 Nis, Serbia"},{"name":"Faculty of Medicine, University of Nis, 18000 Nis, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5982-0159","authenticated-orcid":false,"given":"Mla\u0111an","family":"Golubovi\u0107","sequence":"additional","affiliation":[{"name":"Clinic for Cardiac Surgery, University Clinical Center Nis, 18000 Nis, Serbia"},{"name":"Faculty of Medicine, University of Nis, 18000 Nis, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9921-8488","authenticated-orcid":false,"given":"Marija","family":"Sto\u0161i\u0107","sequence":"additional","affiliation":[{"name":"Clinic for Cardiac Surgery, University Clinical Center Nis, 18000 Nis, Serbia"},{"name":"Faculty of Medicine, University of Nis, 18000 Nis, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4283-4068","authenticated-orcid":false,"given":"Dragan","family":"Mili\u0107","sequence":"additional","affiliation":[{"name":"Clinic for Cardiac Surgery, University Clinical Center Nis, 18000 Nis, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lela","family":"Lazovi\u0107","sequence":"additional","affiliation":[{"name":"Clinic for Cardiac Surgery, University Clinical Center Nis, 18000 Nis, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dalibor","family":"Stojanovi\u0107","sequence":"additional","affiliation":[{"name":"Clinic for Cardiac Surgery, University Clinical Center Nis, 18000 Nis, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8898-948X","authenticated-orcid":false,"given":"Milan","family":"Lazarevi\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, University of Nis, 18000 Nis, Serbia"},{"name":"Institute Niska Banja, 18000 Nis, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5167-4388","authenticated-orcid":false,"given":"Dejan","family":"Markovi\u0107","sequence":"additional","affiliation":[{"name":"Center for Anesthesiology and Reanimatology, University Clinical Center of Serbia, 11000 Belgrade, Serbia"},{"name":"Medical Faculty, University of Belgrade, 11000 Belgrade, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dragana","family":"Uni\u0107-Stojanovi\u0107","sequence":"additional","affiliation":[{"name":"Medical Faculty, University of Belgrade, 11000 Belgrade, Serbia"},{"name":"Institute for Cardiovascular Diseases Dedinje, 18000 Belgrade, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"373","DOI":"10.1093\/eurheartj\/ehaa612","article-title":"2020 ESC Guidelines for the diagnosis and management of atrial fibrillation developed in collaboration with the European Association for Cardio-Thoracic Surgery (EACTS): The Task Force for the diagnosis and management of atrial fibrillation of the European Society of Cardiology (ESC) Developed with the special contribution of the European Heart Rhythm Association (EHRA) of the ESC","volume":"42","author":"Hindricks","year":"2021","journal-title":"Eur.
