Question 123#

A 28-year-old male smoker presented after wakeup typical inaugural chest pain. The 12-rest ECG at admission is shown in Figure below.

He is transferred immediately to the catheterization laboratory. What is the most likely finding?

a. Occlusion of a large diagonal branch
b. Occlusion of the left anterior descending coronary artery
c. Occlusion of the left circumflex coronary artery
d. Occlusion of the RCA
e. Normal coronary angiogram

Correct Answer is B

Comment:

Occlusion of the left anterior descending coronary artery. The coronary angiography showed an occlusion of the proximal left anterior descending coronary artery. The fact that the vessel perfused the apex including the inferoapical portion of the left ventricles explains the ST elevations in the anterior and inferior leads.
