Apelin-to-total cholesterol ratio predicts long-term major adverse cardiovascular events in ST-elevation myocardial infarction patients after primary percutaneous coronary intervention: a retrospective cohort analysis

A lower Apelin/TC ratio at admission independently predicted long-term MACEs in STEMI patients post-PCI, reflecting interplay between lipid burden and Apelin's cardioprotective effects. This ratio may enhance risk stratification by capturing dual metabolic and inflammatory pathways. Further validation is warranted to establish its clinical utility in guiding targeted therapies.
