Soluble Suppression of Tumorigenicity 2 as a Biomarker for Atrial Fibrillation Detected After Stroke: A Retrospective Clinical Study
This retrospective study of 970 stroke/TIA patients found that elevated sST2 levels independently predicted atrial fibrillation detection after stroke (AFDAS), with sST2 showing superior predictive value (AUC 0.815) compared to conventional risk factors. Adding sST2 to a conventional risk model significantly improved prediction accuracy for AFDAS in acute stroke patients.
