A 60-year-old man experiences episodes of severe substernal chest pain every time he performs a task that requires moderate exercise. The episodes have become more frequent and severe over the past year, but they can be relieved by sublingual nitroglycerin. On physical examination, he is afebrile, his pulse is 78/min and regular, and there are no murmurs
or gallops. Which of the following cardiac lesions is most likely to be present?
Rheumatic mitral stenosis
Serous pericarditis
Restrictive cardiomyopathy
Coronary atherosclerosis

The statement below is TRUE about fatty streak, EXCEPT...
It is flat macules that coalesce into elongated lesions, 1 cm or more in length
It composed of lipid-filled foamy macrophages
It can cause a significant flow disturbance.

the subendocardial zone due to...
it
is the last area to receive blood
it is exposed to relatively high
intramural pressures,
Distal occlusion of the
same vessel may affect only the apex
The subendocardial region is most vulnerable to
hypoperfusion and hypoxia
