Head-to-head comparison of the ability of the cardiometabolic index and triglyceride–glucose index to predict 3-year major adverse cardiovascular events in patients with atrial fibrillation: insights from a community cohort

CMI and the TyG index function as robust, independent predictors of 3-year MACEs in patients with atrial fibrillation, and may help identify metabolically impaired individuals who are not adequately captured by conventional risk scores. The TyG index, in particular, offers strong predictive accuracy combined with ease of measurement from routine laboratory tests, making it widely accessible across diverse healthcare settings. These simple, cost-effective indices enable the prompt recognition of high-risk patients and facilitate timely initiation of preventive interventions to reduce cardiovascular morbidity and mortality, serving as practical adjuncts to the CHA2DS2-VASc score for more precise risk stratification and personalized management of AF.
