Predictive value of metabolic score for insulin resistance and triglyceride glucose-BMI among patients with acute myocardial infarction in 1-year follow-up

BACKGROUND: Recently two indicators - metabolic score for insulin resistance (METS-IR) and triglyceride glucose-BMI (TyG-BMI) have been proposed as surrogate markers of IR and potential cardiovascular risk factors. The aim of the study was to assess the predictive value of METS-IR and TyG-BMI concerning the incidence of major adverse cardiovascular events (MACE) and all-cause mortality in 1-year follow-up among patients admitted with acute myocardial infarction (AMI). METHODS: Two thousand one hundred fifty-three patients with a median age of 68 years were enrolled in the study. Patients were divided into two groups according to the type of AMI. RESULTS: MACE occurred in 7.9% of the patients in the ST-segment elevation myocardial infarction (STEMI) group and in 10.9% of the non-STEMI (NSTEMI) group. No significant difference in median MACE-IR and TyG-BMI between patients with and without incidence of MACE was found in both groups. None of the examined indices were predictors of MACE in the STEMI and NSTEMI groups. Moreover, both of them did not predict MACE in subgroups of patients classified according to the presence of diabetes. Finally, METS-IR and TyG-BMI were significant predictors of 1-year morality, however with low prognostic value and only in univariate regression analysis. CONCLUSION: METS-IR and TyG-BMI should not be used in predicting MACE among patients with AMI.
