Increased Preoperative Serum Apoptosis Marker Fas Ligand Correlates With Histopathology and New‐Onset of Atrial Fibrillation in Patients After Cardiac Surgery

Preoperative evaluation of serum apoptosis marker Fas is useful to identify patients at risk for POAF undergoing cardiac surgery. Fas but not TRAIL correlates with the documented degree of atrial apoptosis and atrial fibrosis in RAA tissue. Further studies need to identify the prospective role of Fas in predicting POAF events.
