Background: Atrial fibrillation (AF) is an important cause of stroke. Continuous electrocardiography (ECG) monitoring with software-based analysis algorithms has been suggested to enhance the AF detection rate. We investigated the ability of stroke risk analysis (SRA) in the detection of AF in acute stroke patients. Methods: Consecutive stroke patients numbering 1,153 were screened. Patients with cardioembolic stroke related to AF (n = 296, paroxysmal n = 63, persistent n = 233) and patients with cryptogenic stroke (n = 309) after standard diagnostic work-up (bedside ECG monitoring, ultrasound, transesophageal echocardiography, 24 h Holter ECG) received SRA during their stay at the Stroke Unit. Determination of AF risk by SRA in the patients with AF and in the patient group with cryptogenic stroke was assessed and compared. Results: Median SRA monitoring analysis time was 16 h (range 2–206 h, interquartile range 10–36). In AF patients, SRA also detected a possible or definitive AF in 98%. The overall sensitivity of SRA to detect possible or definitive AF in patients with proven AF by standard diagnostic work up and cryptogenic stroke was 98%, specificity 27%, positive predictive value 56%, and the negative predictive value (NPV) was 92%. Area under ROC curve was 0.622. Conclusion: SRA was found to be highly sensitive to detect possible or definitive AF in clinical routine within a short monitoring time. However, low specificity and poor accuracy do not allow diagnosing AF by SRA alone, but with the high NPV compared to current diagnostic standard, it is a valid diagnostic tool to rule out AF. Thereby, SRA is a contribution to clarify stroke etiology.

Abstract Funding Acknowledgements Plaqueimage Background Atrial fibrillation (AF) is the most common supraventricular rhythm disturbance and pulmonary vein (PV) isolation has an important role in rhythm control treatment strategies of this disease. Various anatomical and clinical characteristics have been well established as predictors of the risk of recurrence following ablation procedures, but the role of epicardial fat tissue (EFT) in the recurrence of AF has not been elucidated so far. Purpose To investigate the influence of left atrial size and EFT volume in the recurrence of AF after pulmonary vein ablation, during a 6-month follow-up. Methods A total of 40 patients, 52.5% with paroxysmal and 47.5% with chronic AF underwent PV isolation using radiofrequency and cryoablation techniques. EFT was determined using cardiac computed tomography angiography (CCTA) associated with advanced image post-processing techniques. Results In patients who developed AF recurrence at 6 months after AF ablation, the volume of EFT and of left atrium were significantly larger than in the group who maintained sinus rhythm (202.5 ± 64.56 ml vs. 138 ± 55.74 ml, p = 0.01 for EFT, and 149.3 ± 4.66 ml vs. 90.63 ± 5.19 ml, p <0.0001 for left atrial volume, respectively). The left ventricular ejection fraction was significantly lower in patients with AF recurrence (50.25 ± 6.54% vs. 54.22 ± 3.95%, p = 0,04). The analysis of AF recurrence between the two different ablation techniques did not show any difference in recurrence rates between radiofrequency and cryoablation methods (29% vs. 23%, respectively p = 0.73). At the same time, recurrence rates after AF ablation were not influenced by the main cardiovascular risk factors (age, hypertension, dyslipidemia and smoking) and was not associated with different risk scores (CHA2DS2-VASc and HAS-BLED). Conclusion Patients with AF recurrence after pulmonary vein ablation present significantly higher EFT or left atrial volumes compared to patients who maintained sinus rhythm. This indicates the inflammatory mediated response, usually accompanied by an increased amount of EFT, could be associated with the risk of AF recurrence following catheter ablation of the pulmonary veins.
