Summary
This summary is machine-generated.An elevated triglyceride-glucose (TyG) index is linked to myocardial injury after non-cardiac surgery (MINS). Monitoring this index may help manage patients at risk for MINS.
Area Of Science
- Cardiology
- Perioperative Medicine
- Biomarkers
Background
- The triglyceride-glucose (TyG) index is a marker of insulin resistance.
- Elevated TyG index is associated with cardiovascular events.
- The relationship between TyG index and myocardial injury after non-cardiac surgery (MINS) is not well understood.
Purpose Of The Study
- To investigate the association between preoperative triglyceride-glucose (TyG) index and the incidence of myocardial injury after non-cardiac surgery (MINS).
Main Methods
- A cross-sectional study was conducted at Meizhou People's Hospital.
- Adult patients undergoing general anesthesia were included.
- The preoperative TyG index was calculated using triglyceride and fasting blood glucose levels, and MINS was defined by postoperative troponin measurements.
Main Results
- The study included 889 patients, with an 8.3% incidence of MINS.
- The TyG index demonstrated a higher discriminatory ability for MINS compared to triglyceride or fasting blood glucose alone.
- An elevated preoperative TyG index was independently associated with an increased risk of MINS (OR 1.75, 95% CI 1.21 to 2.52).
Conclusions
- The preoperative triglyceride-glucose (TyG) index is an independent predictor of myocardial injury after non-cardiac surgery (MINS).
- Perioperative monitoring of the TyG index could aid in managing patients susceptible to MINS.
