Ischaemia-modified albumin
Pathway / Myocardial injury (shared endpoint)

Ischaemia-modified albumin

protein

Ischaemia-modified albumin accumulates during acute myocardial ischaemia as a product of hypoxia-induced and oxidative-stress-dependent albumin metal-binding alteration, serving as an early injury-phase biomarker.

Cascade stepMyocardial injury (shared endpoint)
Confidencehigh
RationaleEarly myocardial ischaemia marker; albumin modification by hypoxia/oxidative stress.
Druggability
Not assessed (no mapped human gene target).

Type I vs non-Type I discrimination

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.
