ML techniques were applied to predict the 1\u2010year risk of developing new\u2010onset AF based on the following variables: age, BMI, sex, smoking, hypertension, diabetes, coronary artery disease, chronic kidney disease, dyslipidaema, history of stroke or transient ischaemic attack, vascular heart disease, left atrial enlargement (LAE) and congestive heart failure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Study population consists of 100 patients (48% male, mean age 66.0\u2009\u00b1\u200918.0\u2009years), of whom 24 developed AF (24%) after 1\u2010year follow\u2010up. The CatBoost ML model achieved the highest AUC (.857, 95% CI .671\u2013.999) when compared to other ML models and all clinical risk scores.
