Association of the preoperative triglyceride-glucose index with postoperative atrial fibrillation following esophagectomy: a retrospective cohort study with a focus on non-diabetic patients (opens in new tab)

BackgroundPostoperative atrial fibrillation (POAF) is common after esophagectomy. The triglyceride-glucose (TyG) index is an accessible cardiometabolic marker derived from fasting triglyceride and glucose levels, but its relationship with POAF after esophagectomy, especially in patients without diabetes mellitus, remains unclear. We evaluated the association between preoperative TyG and POAF and assessed whether TyG added information beyond selected clinical risk factors.MethodsThis single-ce...
