The ABC-Death Score for Mortality Prediction in Patients With Atrial Fibrillation Undergoing Catheter Ablation

Preablation biomarkers associated with ABC-death score were independently related to increased all-cause and cardiac mortality risk. Despite the overestimation of the event rate, the ABC-death score outperformed the CHA₂DS₂-VASc score in discriminating and reclassifying mortality risk, especially for cardiac mortality.
