Blood Vessels Flashcards
Key initiating event in essential hypertension
Reduced Na excretion
Secondary hypertension that involves a gain of function mutation of ENaC channel resulting to salt sensitive hypertension
Liddle syndrome
Vascular pathology in hypertension where there is eosinophilic hyaline material with associated luminal narrowing
Hyaline arteriolosclerosis
Cells in atherosclerosis that is composed of oxidized lipoproteins that accumulate in macrophages and induce release of growth factos and cytokines
Foam cells
Most common sites of atherosclerosis
Lower abdominal aorta Coronary arteries Popliteal Internal carotid Circle of Willis
Critical stenosis level in atherosclerotic arteries where ischemia starts
70%
Most common cause of aortic dissection
Intimal tear
Most common form of vasculitis among older individuals
Giant cell arteritis
Most common vessel affected in Giant Cell arteritis
Temporal
Most common vessel involved in Takayasu arteritis
Branches of aortic arch
Branches of aortic arch
