The triglyceride-glucose index might be a better indicator for predicting poor cardiovascular outcomes in chronic coronary syndrome

Abstract Background Abnormal glucose, and lipid metabolism all play major roles in the process of atherogenesis and are thus substantial risk factors for the development of coronary artery disease. Purpose We sought to investigate whether the triglyceride-glucose index (TyG) and the Atherogenic Index of Plasma (AIP), surrogates for atherosclerosis, are linked to major adverse cardiovascular events (MACE) in patients with Chronic Coronary Syndrome (CCS). Methods and Results Seven hundred ten-five consecutive patients with intermediate risk for CCS who presented to the outpatient clinic between June 2020 and August 2022 were included retrospectively. MACE included non-fatal myocardial infarction, heart failure, cerebrovascular events, non-cardiac mortality, and cardiac mortality. The composite of MACE was determined to be the primary outcome at follow-up after discharge. Secondary outcomes were defined as each individual parameter of MACE. For the primary outcome's time-to-event analysis, the Kaplan-Meier plots, and Cox proportional hazard models were done.The overall population’s median age was 55 years, with males accounting for 58%. The median follow-up time was 17 months. On multivariate cox regression analysis, age, hypertension, Coronary Artery Disease-Reporting and Data System score, and TyG index were found to be independent predictors of the primary outcome. The primary outcome rate was higher in individuals with high TyG than in those with low TyG (18.7% vs 3.8%, p<0.001). Likewise, patients with high TyG had statistically higher rates of cerebrovascular events, heart failure, non-fatal MI, non-cardiac mortality, and cardiac mortality than the latter. Conclusion We found that the TyG might predict poor cardiovascular outcomes in CCS patients.Table 1Figure 1
