stearic acid
metaboliteStearic acid depletion post-myocardial infarction indicates altered fatty acid oxidation and metabolic stress in damaged myocardium.
Pathway placement
Cascade stepOff-pathway / systemic markers
Confidencelow
RationaleSaturated fatty acid; downregulated post-MI metabolite.
Also acts inMyocardial injury, Lipid entry/oxidation
Druggability
Not assessed (no mapped human gene target).
Type I vs non-Type I discrimination
ScoresLow-confidence (proxy)
R — rupture / Type-I52
C — non-Type-I59
A — assay feasibility42
E — evidence strength25
T1DI (composite)5
Specificity differential (R−C)-7
Non-Type-I axis panel
Does this marker also move in each non-Type-I setting? mag 0–3; higher means less Type-I-specific. n/a = no evidence retrieved, which is not the same as no change.
No non-Type-I axis evidence retrieved.
Tier: light (literature co-occurrence proxy — lower confidence). See the discrimination table for all markers.
