Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) show BMI-dependent cardiovascular benefits in type 2 diabetes patients. These agents also provide consistent kidney protection, highlighting the importance of BMI stratification for treatment decisions.
Area of Science:
- Cardiology
- Endocrinology
- Nephrology
Background:
- Cardiovascular benefits of GLP-1 RAs may differ by BMI.
- Limited evidence exists on BMI-specific outcomes for GLP-1 RA use.
- Type 2 diabetes management requires consideration of cardiovascular and kidney health.
Purpose of the Study:
- To investigate GLP-1 RA associations with cardiovascular and kidney outcomes across BMI categories.
- To compare GLP-1 RA use against DPP-4 inhibitors in patients with type 2 diabetes.
- To determine if BMI influences the effectiveness of GLP-1 RAs.
Main Methods:
- Retrospective cohort study using the Chang Gung Research Database (2011-2022).
- Propensity score matching was used to compare GLP-1 RAs with DPP-4 inhibitors within BMI categories (<25 and ≥25).
- Primary outcomes included major adverse cardiovascular events (MACE) and composite kidney outcomes.
Main Results:
- GLP-1 RAs were associated with reduced cardiovascular death (HR, 0.62) and heart failure hospitalization (sHR, 0.77) in patients with BMI ≥25.
- Cardiovascular benefits increased with higher BMI.
- Kidney outcomes were consistently protected across all BMI strata.
Conclusions:
- GLP-1 RA use demonstrates BMI-dependent cardiovascular benefits in type 2 diabetes.
- Consistent kidney protection was observed across BMI categories.
- BMI stratification is crucial for optimizing GLP-1 RA treatment decisions.
