Question:
A 60 year-old man with coronary artery disease has been hospitalized for a large myocardial infarction he suffered 5 days ago. He suddenly develops hypotension and prominent jugular vein distention. On cardiac exam, his heart sounds are muffled. His pulse is palpably weaker during inspiration. What is the most likely diagnosis?
Correct Answer: C. Myocardial wall rupture
This patient has developed cardiac tamponade (acute build-up of fluid in the pericardial space) 5 days after a myocardial infarction. This patient has all three features of Beck’s triad: hypotension, JVD, and distant heart sounds. Myocardial wall rupture most commonly occurs between 4 and 7 days after an MI.
