2 How does aspirin work to prevent cardiac ischemia?

By blocking the enzyme, COX-1 (cyclo-oxygenase-1), produced by platelets, that causes clumping.

By inhibiting the binding of adenosine diphosphate (ADP) to the receptor on the platelet surface that allows clumping.

By inhibiting the binding of glycoproteins IIa/IIIa to the receptor on the platelet surface that allows clumping.

By modifying the leukotrienes in the inflammatory cascade.
