4 arterial pathological consequences of atherosclerosis
artery stenosis
arterial thrombosis/ embolism
aneurysm 
dissection
artery stenosis
arterial thrombosis/ embolism
aneurysm
dissection
how does arterial thrombosis occur
thin fibrous plaque ruptures 
collagen release stimulates COAGULATION cascade
thin fibrous plaque ruptures
collagen release stimulates COAGULATION cascade
what's an aneurysm
abnormal DILATATION & reduced elasticity of artery wall
media weakened by atherosclerosis ---> RUPTURE!
abnormal DILATATION & reduced elasticity of artery wall
media weakened by atherosclerosis ---> RUPTURE!
what's a dissection
media SPLIT --> sudden TEARING pain
media SPLIT --> sudden TEARING pain
what's LVH, why and how is it dysfunctional (3)
fibrous, collagenous = stiff & less complaint
- DIASTOLIC dysfunction
- DISARRAY of electric impulse - arrhythmias
- thicker= reduced PERFUSION
if repeated clinic BP is >140/90 what do you do?

how is this done?
offer ABPM to confirm HTN diagnosis
