Answer MCQ Cardiology 36A 74 year old man presents with severe chest pain to the emergency room, and is found to have a widened mediastinum on chest radiograph and a murmur of aortic insufficiency on examination. He dies on the operating table from blood loss from a ruptured but very dilated ascending aorta. At autopsy, severe aortic atherosclerosis, especially in the ascending aorta, is seen together with a longitudinal intimal ridging resembling tree bark affecting the ascending aorta. the aortic root is also dilated. Histological sections of the aortic arch confirm the atherosclerotic plaques, and also show obliterative endarteritis of the vasa vasorum.

A. Kawasaki arteritis; atherosclerosis
B. Atherosclerosis with secondary bacterial aortitis
C. Aortic dissection., Type A

Of the following, which is the most likely cause of death based on this history?
A. Pulmonary embolism originating in left ventricular mural thrombus

If this man died about 2 hours after his symptoms began, before he could be taken for angioplasty, you would expect the routinely stained sections from his anterior heart wall to show:
A. Normal myocardium
B. Poly morphonucleocytes (PMNs), edema and congestion in hypereosinophilic, wavy myocardium
C. Macrophages and lymphocytesin degenerating necrotic myocardium
D. Proliferating tiny vessels and early fibroblast proliferation
E. Hyalinized fibrous tissue
Answer MCQ Cardiology 32A 57 year old man presents with a 35 minute history of severe chest pain radiating down his left arm, associated with shortness of breath.

The histological finding you would expect in the left anterior descending artery (LAD).
A. Circumferential medial fibrosis
B. Circumferential intimal fibrosis
