Which is NOT a typical complication following an MI?

• A. Mural thrombus
• B. Pericarditis
• C. Malignant hypertension
• D. Myocardial rupture

Answer: (C)

Post-MI complications arise from the loss of myocardial integrity and the ensuing inflammatory response, which can lead to thrombus formation on a damaged wall, pericardial inflammation, or mechanical failure of the heart. A mural thrombus can develop on a scarred, poorly contracting area and may embolize. Early pericarditis results from inflammation of the pericardium over the infarct (fibrinous pericarditis), and myocardial rupture is a feared mechanical complication when necrotic tissue is weakest, potentially causing tamponade or a septal defect. Malignant hypertension is not a typical direct consequence of an MI; it may occur independently or coexist but is not a characteristic post-infarction complication.
