Cardiovascular Disease And intro of Heart Diseases Flashcards
(51 cards)
What is the most common disease of arteries?
Atherosclerosis
-complications account for the majority of these deaths
What progress are the lesions of atherosclerosis assumed to have?
From fatty streaks to fibrous plaques to “complicated lesions”
What stage of atherosclerosis progression is asymptomatic and are considered to be precursors of advanced lesions?
Fatty streak
-seen first in very young
What stage of atherosclerosis progression has characteristic features that include enlargement, plaque rupture and ulceration, hemorrage, degenerative changes, calcification and formation of superimposed thrombi?
complicated lesion (atheroma)
- Foam cells
- becomes asymptomatic (end stage)(advance)
MATURE
What are traditional “hard” risk factors associated with atherosclerosis?
Hyperlipidemia, cigarette smoking, hypertension, diabetes mellitus
What are the proposed mechanisms of atherosclerosis pathogenesis?
Reaction to injury and repair hypothesis, or monoclonal hypothesis
What contributes to stable angina, chronic ischemic atrophy of myocardium, atherosclerotic dementia, leg claudication, intestinal angina?
Stable plaques (fixed stenosis)
What is causing pain in angina?
Ischemic pain
What type of occlusion manifestation of atherosclerosis gives rise to thrombosis?
Unstable plaques
-characterized by enlarged lipid core, thinner fibrous cap and accumulated inflammatory cells
What is the sclerosis that is associated with degeneration and dystrophic calcification of media of “muscular” arteries, typically in older adults?
Monckebergs (medial) Sclerosis
- In tunica media
What is the most common type of atherosclerosis?
Hyaline arteriolar sclerosis
What causes increased risk for thrombosis, structural changes that lead to aneurisms and obliterating scars?
arteritis
- arterial disease of inflammatory origin
- increased risk for obstruction
What is the most common form of arterial disease?
atherosclerosis
What is Goodpasture’s syndrome?
Antibodies directed against components of vessel wall in arteritis
What is the most common arteritis in older adults?
Giant cell (temporal) arteritis -superficial temporal artery
What is a disease of young male smokers?
Thromboangiitis obliterans (buerger’s disease)
What is a segmental, necrotizing vasculitis of small and medium arteries?
polyarteritis nodosa
What is called the “pulseless disease”?
Taykayasu’s arteritis “aortic arch disease”
-rare, idiopathic disease in younger adults
What is associated with reversible spasmodic contraction and occlusion of arteries?
Raynaud’s phenomenon (or disease or primary)
-reaction to cold in small arteries (turns affected structures white then blue then red
Where is the most common area that atherosclerotic (tension) aneurysms occur
Abdominal aorta, below level of renal arteries
What is mostt famous for causing anurysms of proximal aorta that may rupture?
Syphilitic aneurism
- tree bark grooves on intima and occlusion of coronary and other ostia and it may cause dialation of aortic valve ring
Most common places to find atherosclerotic?
aorta and common iliac
what is associated with thoracic aorta aneurysm?
dissecting aneurism
-false aneurysm
What is associated with dissecting aneurysm (defect in gene for fibrillin)?
Marfans syndrome
-cardiovascular: weakened aorta, floppy cardiac valves
