Acetoacetate
metaboliteA ketone body and metabolic intermediate reflecting energy metabolism dysregulation and ischemic metabolic stress in MI.
Pathway placement
Cascade stepOff-pathway / systemic markers
Confidencemedium
RationaleKetone body and energetic biomarker; metabolic stress marker not plaque-specific.
Also acts inLipid entry/oxidation
Druggability
Not assessed (no mapped human gene target).
Type I vs non-Type I discrimination
ScoresLow-confidence (proxy)
R — rupture / Type-I20
C — non-Type-I64
A — assay feasibility42
E — evidence strength23
T1DI (composite)3
Specificity differential (R−C)-43.7
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.
