Which of the following describes the goal of therapies after MI and PCI?

• A. Cure cancer
• B. Normalize thyroid function
• C. Treat infection
• D. Prevent clot formation

Answer: (D)

Preventing clot formation after MI and PCI is the central goal because plaque rupture and the arterial injury from stenting create a highly pro-thrombotic environment. If a thrombus forms, it can re-occlude the coronary artery, causing reinfarction or stent thrombosis. Therefore, therapies focus on antithrombotic strategies—antiplatelet drugs like aspirin and P2Y12 inhibitors to stop platelet activation and aggregation, and sometimes anticoagulants during the procedure—with a planned period of dual antiplatelet therapy to keep the vessel open. The other options (cure cancer, normalize thyroid function, treat infection) don’t address this acute thrombotic risk and aren’t the target of post-MI/PCI treatment.
