To assess the relationship between triglyceride levels and cardiovascular events following myocardial infarction (MI) and inform future trial designs.
Key Findings:
Lowering triglycerides by approximately 1.0 mmol/L was associated with reduced risk of major adverse cardiovascular events (MACE).
Patients with the highest triglyceride reductions (≥0.6 mmol/L) had a 14% lower risk of MACE compared to those with minimal changes.
Only 27% of patients achieved a triglyceride reduction of ∼1.0 mmol/L, primarily those starting with levels ≥2.2 mmol/L.
Interpretation:
The findings suggest that significant triglyceride reductions post-MI may lower cardiovascular risk, particularly in patients with elevated baseline triglyceride levels.
Limitations:
The study is observational and cannot establish causation.
Results may not be generalizable to populations outside of the SWEDEHEART registry.
Conclusion:
Future clinical trials should focus on patients with elevated triglyceride levels (≥2.2 mmol/L) to achieve meaningful reductions and assess cardiovascular benefits.
Analysis of nearly 1.6 million veterans showed preexisting community health inequities largely explained poststorm cardiovascular and respiratory outcomes.
