Question: Are platelet monocyte aggregates and monocyte chemoattractant protein-1 inhibited by aspirin in critical limb ischaemia?
Answer: Despite aspirin treatment CLI patients have higher platelet activation and MCP-1 expression than controls and claudicants. With increasing severity of disease aspirin is unable to suppress markers of platelet activation and pro-atherosclerotic chemokine expression which may represent another form of aspirin resistance.
no
