hypercoagulable states Flashcards
virchows triad
- endothelial damage
- stasis of blood
- hypercoagulability
hypercoagulable states include
post-op, fall, hip fracture, trauma, long plane flights, malignancy
elevated homocysteine is associated with
arterial and venous clots
homocysteine levels are lowered by
folate
nephrotic syndrome is hypercoagulable state because loss
of anti-clotting factors in urine (antithrombin III)
estrogen containing oral contraceptives are contraindicated if
age >35 and >15 cigs per day
factor V leiden mut
factor V is not inactivated by activated protein C so factor V remains active longer
factor V leiden mut is due to
point mutation in factor V gene
prothrombin gene mutation
prothrombin 20210
antithrombin III deficiency classically presents as
heparin resistance
protein C def associated w
warfarin skin necrosis
initial warfarin therapy is causes
decreased protein C but if already protein C def it is markedly decreased
result of protein C def results in
thrombosis
antiphospholipid syndrome occur in associated with
lupus
3 imp clinical consequences of antibodies
- increased risk of venous & arterial thrombosis
- increased PTT
- false positive syphilis
