Prostacyclin
metaboliteProstacyclin maintains endothelial function and opposes platelet activation, protecting against thrombosis in Type 1 MI.

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.
