Utility of Novel Lipid Parameters for Risk Stratification in Patients with Diabetes and STEMI-from a Prospective Study.

Among diabetic patients with TyG index at or above the median, those with fewer elevated lipid parameters had significantly better ischemic stroke-free survival.

• Group 1 (0-1 lipid parameters increased) and group 2 (2-4 lipid parameters increased) had significantly better ischemic stroke-free survival than other groups
• This difference was statistically significant (p=0.025)
• This finding was specific to diabetic (DM) patients when TyG index ≥ median
• The analysis was conducted within a prospective cohort of 1580 individuals, both diabetic and non-diabetic

Adding novel lipid-associated parameters and the TyG index to a conventional lipid risk factors model improved risk reclassification for ischemic stroke.

• Improvement was validated by improved net reclassification index (p<0.05)
• Integrated discrimination improvement also supported the enhanced model performance
• The addition led to significant reclassification of individuals into risk categories
• Three novel lipid biomarkers evaluated were proprotein convertase subtilisin/kexin type 9 (PCSK9), fatty acid-binding protein 4 (FABP4), and Resolvin D1
• These were evaluated alongside six conventional lipid parameters

Three novel lipid biomarkers from diverse pathophysiological pathways were evaluated alongside six conventional lipid parameters in a cohort of 1580 individuals.

• The novel biomarkers were PCSK9, FABP4, and Resolvin D1
• The cohort comprised 1580 individuals, both diabetic and non-diabetic
• The study was a prospective cohort design
• The primary outcome followed was incident ischemic stroke events
• The TyG (triglyceride-glucose) index was included as an insulin resistance marker alongside the lipid parameters

A biomarker score encompassing innovative lipid-associated biomarkers alongside the TyG index, when incorporated into a traditional risk assessment framework, significantly enhanced evaluation of ischemic stroke events in STEMI patients with diabetes.

• The study population consisted of myocardial infarction (STEMI) populations afflicted with diabetes mellitus
• The biomarker score combined novel lipid-associated biomarkers with the TyG index
• The enhancement was demonstrated over a conventional lipid risk factors model alone
• Insulin resistance was identified as playing an integral role in abnormalities of glucose and lipid metabolism in myocardial infarction patients
