Zusammenfassung:Abstract Background Guidelines of the European Society of Cardiology recommend risk assessment to identify appropriate candidates for anticoagulation in patients with atrial fibrillation (AF). However, scores such as the CHA2DS2VASc-score show only a modest performance for prediction of adverse events. Methods This retrospective single-center all-comer sub-study from the Heidelberg Registry of Atrial Fibrillation (HERA-FIB) enrolled 9,995 consecutive patients with non-valvular AF, presenting to the emergency department (ED) from June 2009 until March 2020. We tested the performance of the CHA2DS2VASc-score with and without high sensitive cardiac troponin T (hs-cTnT) for prediction of a adverse events such as stroke or major bleedings. Per CHA2DS2VASc, stroke risk was classified as low (0 point in men, ≤1 point in females), intermediate, or high (≥2 points in men and ≥3 points in females). Results Performance of the CHA2DS2VASc-score for the prediction of the composite endpoint consisting of stroke and major bleeding was poor (AUC 0.600, 95%CI: 0.590-0.610) but improved after addition of hs-cTnT as a variable across all risk categories (AUC 0.618 95%CI: 0.608-0.628, ∆AUC 0.0182 95%CI: 0.0124-0.0240, p
