Mannose
Pathway / Off-pathway / systemic markers

Mannose

metabolite

Mannose reflects altered carbohydrate metabolism and systemic stress in acute myocardial infarction.

Pathway placement
Cascade stepOff-pathway / systemic markers
Confidencelow
RationaleSimple sugar; systemic metabolic marker associated with MI mortality risk but not plaque-specific.
Druggability
Not assessed (no mapped human gene target).

Type I vs Type II discrimination

ScoresLow-confidence (proxy)
R — rupture / Type-I
70
C — confounder / Type-II
93
A — assay feasibility
42
E — evidence strength
35
T1DI (composite)
6
Specificity differential (R−C)-22.8
Confounder panel (Type-II drivers)
No confounder evidence retrieved.
Tier: light (literature co-occurrence proxy — lower confidence). See the discrimination table for all markers.
