Reactive oxygen species
metaboliteReactive oxygen species generated during plaque inflammation oxidize lipids, activate platelets, and cause vascular dysfunction in Type 1 MI.
Pathway placement
Cascade stepPlaque inflammation

RationaleOxidative mediator of plaque inflammation and atherosclerosis; drives lipid oxidation and platelet activation.
Also acts inLipid entry/oxidation, Platelet activation
