linoleic acid
metaboliteLinoleic acid depletion in acute myocardial infarction reflects altered lipid metabolism, oxidative stress, and ischemia-reperfusion-mediated metabolic derangement.
Pathway placement
Cascade stepOff-pathway / systemic markers
Confidencemedium
RationalePolyunsaturated fatty acid; dysregulated in AMI and ischemia-reperfusion injury.
Also acts inLipid entry/oxidation, Myocardial injury
Druggability
Not assessed (no mapped human gene target).
Type I vs Type II discrimination
ScoresLow-confidence (proxy)
R — rupture / Type-I68
C — confounder / Type-II78
A — assay feasibility42
E — evidence strength31
T1DI (composite)6
Specificity differential (R−C)-10.2
Confounder panel (Type-II drivers)
No confounder evidence retrieved.
Tier: light (literature co-occurrence proxy — lower confidence). See the discrimination table for all markers.
