Hyaluronic Acid
metaboliteHyaluronic acid is an ECM regulator whose elevated plasma levels reflect matrix turnover during atherosclerotic plaque destabilization and erosion.
Pathway placement
Cascade stepFibrous-cap degradation & rupture
Confidencemedium
RationaleExtracellular matrix component; remodeling marker in plaque degradation and endothelial erosion.
Also acts inEndothelial activation/erosion
Druggability
Not assessed (no mapped human gene target).
Type I vs non-Type I discrimination
ScoresNon-Type-I-associated
R — rupture / Type-I0
C — non-Type-I56

Specificity differential (R−C)-55.6
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.
