A 55-year-old male died of a myocardial infarction. Autopsy would most likely reveal:
 
  a. embolization of plaque from the aorta.
  b. decreased ventricular diastolic filling time.
  c. platelet aggregation within the atheroscle-rotic coronary artery.
  d. smooth muscle dysplasia in the coronary artery.

Question 2

A 68-year-old male presents to the ER reporting chest pain. He has a history of stable angina that now appears to be unstable. He most likely has:
 
  a. mild to moderate atherosclerosis.
  b. impending myocardial infarction (MI).
  c. electrical conduction problems in the heart.
  d. decreased myocardial oxygen demand.

Answer to Question 1

ANS: C
The autopsy would reveal platelet aggregation within an atherosclerotic coronary artery. The cause of death is most likely occlusion of the coronary artery, not emboli from the aorta, de-creased filling time, or dysplasia in the artery.

Answer to Question 2

ANS: B
Unstable angina is an indication of impending MI. Unstable angina could be caused by moderate atherosclerosis, altered electrical conduction, or a decrease in myocardial oxygen, but it is an in-dication of impending MI.
