A 55-year-old man presents to the emergency room with crushing
substernal pain and left shoulder pain of 2 hours duration. The pain
is not relieved by sublingual nitroglycerin, and the electrocardiogram
shows ST elevation in several leads. Aspirin and streptokinase therapy
are initiated, and the patient is admitted to the intensive care unit.
The next morning, serum cardiac enzymes are elevated to 4 times the upper
limit of normal, and the electrocardiographic changes are still present.
Which of the following is the most likely diagnosis?
A. Prinzmetal's angina
B. Stable angina
C. Subendocardial infarction
D. Transmural infarction

D transmural .
Consider subendocardial if ST depression.

i believed the correct answer is C. It's a QBank question. The reasoning was that Transmural infarction would be more localized on the EKG findings as compare to Subendocardial. I am not really happy with the explanation. Anyone?

Opps, so very sorry! I was mistaken another question on Qbank, which stated that ST-depression rather than ST-elevation! The correct answer to this question is D. :oops:
