atherosclerotic CV disease Flashcards
which arterial layer proliferates in the pathogenesis of atherosclerosis
media
most plaques in the coronary arteries are
eccentric
fibromuscular plaques are
stable
acute MI will lead to
acute coagulative necrosis
which ventricle most affected by MI
left
where does the MI start
in subendocardial zone but may become transmural
early Myocardial ischemia you will see
contraction bands
in MI, > 16-24 hours after infarct you will see
acute inflammation
days after the infarct you will see
macrophages and loss of cardiomyocytes
weeks to years after infarct you will see
scarring and thinning
in chronic ischemia you may see
Myocytolysis
most cases of sudden death are attributed to
coronary artery stenosis not an infarct
which vascular grafts last longer and do not develop stenosis
arterial grafts -
most common arterial graft
internal thoracic artery
most common venous graft
GSV
