b. anticoagulation to prevent formation of new emboli.
c. dissolution of atherosclerotic plaque at the site of blockage.

The administration of a fibrinolytic agent results in the lysis of the acute thrombus, thus recanalizing, or opening, the obstructed coronary artery and restoring blood flow to the affected tissue. After perfusion is restored, adjunctive measures are taken to prevent further clot formation and reocclusion.
