Free fatty acid (15:1)

lipid

Free fatty acid (15:1) elevation discriminates atherothrombotic MI from Type 2 MI, marking ischemic lipid catabolism.

Pathway placement

Cascade stepMyocardial injury (shared endpoint)

Confidencemedium

RationaleType 1 MI discriminator; reflects lipid mobilization and myocardial metabolic crisis.
