atherosclerosis
defn
degen and inflam disease,
affecting large & med-sized arteries (aorta, coronary, carotid, mesenteric, ilias, femoral, cerebral arteries),
causing thickening and loss of elasticity
ischaemic heart disease
bg & scoping cvs syllabus for dent...
heart function
functions
supply tissues w vital nutrients
facilitates excretion of waste pdts
components needed?
myocardium - pump
valves (part of endocardium) - maintain unidirectional blood flow
conduction system - maintain coordinated pumping rhythm
blood supply - coronary arteries provide sufficient nutrients to heart
FAILURE, can lead to
HEART DISEASE
classification
aetiology / cause
congenital -- shunts, obstruction, metab etc.
acquired
multifactoral
heart failure
the heart is unable to meet the body’s demands (despite compensatory mechanisms)
although the venous filling pressure is normal or raised
