Question 14 of 39:

This patient's EKG suggests that he has high likelihood of occluding the infarct-related coronary artery.

You clicked 'True'

Correct!

Patients with ST elevation have a high likelihood of a coronary thrombus occluding the coronary artery[1,2].

Angiographic evidence of occlusive coronary thrombus may be seen in >90% of patients with ST elevation MI but in only 1% of patients with stable angina and ~35% to 75% of patients with unstable angina or non-ST elevation MI[1,3].
