Table 1

Baseline characteristics of the study participants. AF—atrial fibrillation, M—male, F—female, BMI—body mass index, CAD—coronary artery disease, TIA—transitory ischemic attack, CHA2DS2-VASc Score— the most commonly utilized method to predict thromboembolic risk in atrial fibrillation, HAS-BLED score—a scoring system developed to assess one-year risk of major bleeding in patients taking anticoagulants with atrial fibrillation, SD—standard deviation.

Primary and secondary outcome measures in patients with newly diagnosed AF and chronic AF. CHA2DS2-VASc Score—the most commonly utilized method to predict thromboembolic risk in atrial fibrillation, ACT—anticoagulation therapy, SD—standard deviation. * Thirty–one patients in the newly diagnosed AF group were administered with ACT.
