Hemoglobin
proteinReleased hemoglobin amplifies oxidative stress and promotes platelet activation and thrombosis in acute coronary occlusion.
Pathway placement
Cascade stepPlatelet adhesion & activation
Confidencemedium
RationaleHeme-hemoglobin oxidative stress preceding STEMI; triggers platelet/thrombotic response.

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.
