The demographic profile, risk factors for AF including hypertension, age\u226575 years, transient ischaemic attack or stroke, chronic obstructive pulmonary disease (HATCH) score, electrocardiography features and perioperative factors were determined.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Patients who developed POAF were significantly older. On univariate analysis HATCH score, aortic regurgitation, increased p-wave duration and amplitude in lead II and terminal p-wave amplitude in lead V1 were associated with POAF; as were increased cardiopulmonary bypass time (103.5\u00b133.9 vs 90.6\u00b126.4 min, p=0.001) and increased cross clamp time. On multivariate analysis age (p=0.038), p-wave duration \u2265100 ms (p=0.005), HATCH score (p=0.049) and CBP Time \u2265100 min (p=0.001) were associated with POAF. Receiver operating characteristic curve demonstrated that with a cut-off of \u22652 for HATCH score, POAF could be predicted with a sensitivity of 72.8% and a specificity of 34.7%. Adding p-wave duration in lead II &gt;100 ms and cardiopulmonary bypass time &gt;100 min to the HATCH score increased the sensitivity to 83.7% with a specificity of 33.1%. This was termed the HATCH-PC score.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Patients with HATCH scores \u22652, and those with p-wave duration &gt;100 ms, or cardiopulmonary bypass time &gt;100 min were at greater risk of developing POAF following CABG.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1136\/openhrt-2023-002284","type":"journal-article","created":{"date-parts":[[2023,6,14]],"date-time":"2023-06-14T13:37:29Z","timestamp":1686749849000},"page":"e002284","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":27,"title":["Predictors of atrial fibrillation post coronary artery bypass graft surgery: new scoring system"],"prefix":"10.1136","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3367-3821","authenticated-orcid":false,"given":"Kian","family":"Lotter","sequence":"first","affiliation":[{"name":"Intensive Care, Townsville Hospital and Health Service, Townsville, Queensland, Australia"},{"name":"James Cook University Division of Tropical Health and Medicine, Townsville, Queensland, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sumit","family":"Yadav","sequence":"additional","affiliation":[{"name":"James Cook University Division of Tropical Health and Medicine, Townsville, Queensland, Australia"},{"name":"Cardiothoracic Surgery, Townsville Hospital and Health Service, Townsville, Queensland, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pankaj","family":"Saxena","sequence":"additional","affiliation":[{"name":"James Cook University Division of Tropical Health and Medicine, Townsville, Queensland, Australia"},{"name":"Cardiothoracic Surgery, Townsville Hospital and Health Service, Townsville, Queensland, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Venkat","family":"Vangaveti","sequence":"additional","affiliation":[{"name":"James Cook University Division of Tropical Health and Medicine, Townsville, Queensland, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bobby","family":"John","sequence":"additional","affiliation":[{"name":"James Cook University Division of Tropical Health and Medicine, Townsville, Queensland, Australia"},{"name":"Cardiology, Townsville Hospital and Health Service, Townsville, Queensland, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2023,6,14]]},"reference":[{"key":"2025081612250732000_10.1.e002284.1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.291.14.1720"},{"key":"2025081612250732000_10.1.e002284.2","doi-asserted-by":"publisher","DOI":"10.1093\/ejcts\/ezu551"},{"key":"2025081612250732000_10.1.e002284.3","first-page":"627","article-title":"Postoperative atrial fibrillation: incidence, mechanisms, and clinical correlates","volume":"32","author":"Yadava","year":"2014","journal-title":"Cardiol Clin"},{"key":"2025081612250732000_10.1.e002284.4","doi-asserted-by":"publisher","DOI":"10.1093\/icvts\/ivv326"},{"key":"2025081612250732000_10.1.e002284.5","doi-asserted-by":"crossref","first-page":"1320","DOI":"10.1161\/CIRCULATIONAHA.120.046940","article-title":"Postoperative atrial fibrillation and long-term risk of stroke after isolated coronary artery bypass graft surgery","volume":"142","author":"Benedetto","year":"2020","journal-title":"Circulation"},{"key":"2025081612250732000_10.1.e002284.6","doi-asserted-by":"crossref","unstructured":"Conen D , Wang MK , Devereaux PJ , et al .
