Clinical Report: Association of Cumulative Exposure to TyG-BMI and CVD Risk
Overview
This study investigates the association between cumulative triglyceride-glucose-body mass index (TyG-BMI) exposure and cardiovascular disease (CVD) risk in a Chinese population.
Background
Cardiovascular disease (CVD) remains the leading cause of death globally, necessitating effective risk assessment strategies. Insulin resistance, a key factor in the development of type 2 diabetes, is also recognized as an independent risk factor for CVD. The triglyceride-glucose (TyG) index serves as a practical surrogate marker for insulin resistance, and its combination with body mass index (BMI) into the TyG-BMI index may enhance cardiovascular risk prediction.
Data Highlights
Quartile
Hazard Ratio (95% CI)
Q1
1.00
Q2
1.32 (1.18–1.49)
Q3
1.33 (1.18–1.49)
Q4
1.44 (1.29–1.62)
Key Findings
3,514 incident cardiovascular events occurred during a median follow-up of 10 years.
The risk of CVD increased with higher cumulative TyG-BMI exposure quartiles.
Cox regression analysis showed hazard ratios of 1.32, 1.33, and 1.44 for Q2, Q3, and Q4 compared to Q1.
A significant non-linear relationship was found between cumulative TyG-BMI and CVD risk.
The area under the ROC curve for cumulative TyG-BMI was 0.6047, indicating modestly better performance than TyG and BMI alone.
Clinical Implications
The findings indicate a relationship between cumulative TyG-BMI exposure and CVD risk.
Conclusion
High cumulative TyG-BMI exposure is associated with an increased risk of cardiovascular disease.
