Insulin resistance (IR) represents a pivotal metabolic risk factor, with metabolic abnormalities intricately linked to increased predisposition to cardiovascular, digestive, and immune system disorders. While the triglyceride glucose (TyG) index is widely recognized as a simple and specific surrogate marker for IR, the triglyceride glucose body mass index (TyG-BMI), incorporating obesity metrics, has emerged as a more robust predictor of IR. Growing evidence underscores the strong association between TyG-BMI index and multisystem diseases that span cardiovascular, metabolic, and neoplastic pathways. Monitoring TyG-BMI index enables proactive management of lifestyle modifications, dietary interventions, and physical health strategies, thereby reducing disease prevalence. This review synthesizes the pathophysiological mechanisms underlying TyG-BMI, alongside its clinical utility and cutting-edge research advancements in hypertension, coronary artery disease, stroke, diabetes, non-alcoholic fatty liver disease, hyperuricemia, and cancer. Particular emphasis is placed on the role of TyG-BMI index in influencing disease progression, highlighting its potential as a transformative biomarker for risk stratification and therapeutic targeting across diverse medical disciplines.

Background: The triglyceride-glucose-body mass index (TyG-BMI) is a simple indicator of insulin resistance and is linked to an elevated risk of mortality. Nevertheless, limited research has explored the associations between the TyG-BMI and all-cause and cardiovascular mortality in patients undergoing peritoneal dialysis (PD).
Methods: Patients initiating PD treatment at the Tianjin First Central Hospital's Nephrology Department from July 2013 to February 2024 had triglycerides, fasting blood glucose, height, and weight measured at baseline and monthly during follow-up.

Background: Insulin resistance (IR) is an established independent risk factor for cardiovascular disease (CVD). Although numerous simple surrogate indicators for IR have been proposed, their comparative predictive utility for CVD remains unclear. This study aimed to evaluate the associations between nine IR surrogate indicators and incident CVD and to comparatively assess their predictive capacities using nationally representative data from China.

Purpose: Triglyceride glucose-body mass index (TyG-BMI) represents a combined measure to evaluate insulin resistance and predict cerebral and cardiovascular disease risk and the resulting negative consequences. Nevertheless, the prognostic value of TyG-BMI for predicting outcomes, such as mortality, among critically ill patients in the intensive care unit (ICU-CIP) remains understudied. Our study seeks to ascertain the relation between all-cause mortality (ACM) and TyG-BMI among ICU-CIP, regardless of specific diseases, to recognize individuals at high risk and enhance prediction strategies.

Background: Insulin resistance (IR) is associated with both the anatomical remodeling of the left atrium and the pathogenesis of atrial fibrillation (AF). However, the exact extent of this correlation and its influence on AF recurrence in individuals undergoing radiofrequency catheter ablation (RFCA) remains unclear.
Methods: A total of 910 patients with AF who underwent RFCA were included in this analysis.

Background: Hemorrhagic stroke (HS), accounting for over 40% of stroke-related deaths, imposes a severe global health burden due to high mortality and disability rates. The triglyceride-glucose-body mass index (TyG-BMI), integrating lipid-glucose metabolism and obesity, has shown prognostic value in cardiovascular diseases but remains underexplored in HS populations.
Methods: This retrospective cohort study analyzed 413 HS patients from the MIMIC-IV database.
