High Triglyceride-Glucose Index Predicts Mortality in Patients with Acute Myocardial Infarction in Intensive Care...

Area of Science:

• Cardiology
• Metabolic Syndrome
• Clinical Research

Background:

• Metabolic dysregulation, specifically in triglyceride and glucose metabolism, is a known contributor to cardiovascular diseases.
• Acute myocardial infarction (AMI) patients face significant mortality risks, necessitating improved prognostic tools.

Purpose of the Study:

• To investigate the association between the triglyceride and glucose (TyG) index and mortality rates in patients diagnosed with AMI.
• To evaluate the TyG index as a potential predictor for risk stratification in AMI patients.

Main Methods:

• A retrospective cohort study utilized data from the MIMIC-IV database, including 1,123 AMI patients.
• The TyG index was calculated, and multivariate analyses, including Cox proportional hazards regression, were performed, adjusting for confounders like BMI and diabetes status.

Main Results:

• Patients with higher TyG index values exhibited significantly increased hospital, ICU, and all-cause mortality rates.
• Kaplan-Meier survival analysis revealed lower mortality in patients with a low TyG index compared to those with a high TyG index.
• The TyG index independently predicted all-cause mortality in AMI patients (HR 1.884, p=0.007).

Conclusions:

• The triglyceride and glucose (TyG) index shows promise as a predictive marker for mortality in acute myocardial infarction (AMI) patients.
• The TyG index can assist in the clinical risk stratification of AMI patients, particularly those in the ICU.
