RationaleCell-free DNA released during cardiomyocyte necrosis; AMI severity marker.

Druggability
Not assessed (no mapped human gene target).
Type I vs non-Type I discrimination
ScoresLow-confidence (proxy)
R — rupture / Type-I63
C — non-Type-I72
A — assay feasibility45
E — evidence strength32
T1DI (composite)7
Specificity differential (R−C)-9.2
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.
