25
[TIA]: 1st line Mx without warfarin indication?
Clopidogrel (75mg/d)
Aspirin (300mg/d)
Dypiridamole (200mg/12hrs)
26
[TIA]: The dose of aspirin after 2 week
aspirin 75mg/d
27
[TIA]: MOA of clopidogrel
inhibits platelet aggregation by modifying platelet ADP-R
28
[TIA]: Dypiridamole should be added to aspirin. What does it do
increase cAMP
Decrease Thomboxane A2
29
[TIA]: CVS risk factor control includes DM, hyperlipidaemia, smoking and a BP of < ....
140/85
30
[TIA]: Carotid endarterectomy indication is (2)
>70% stenosis at origin of internal carotid artery
risk is low
31
[TIA]: how soon should surgery be performed
within 2 weeks of presentation
32
[TIA]: is aspirin stopped before carotid endarterectomy surgery
no
33
[TIA]: peri-operative monitoring of middle cerebral artery blood flow done by
transcranial doppler
34
[TIA]: What ∆∆ is ruled out by checking glucose
Hypoglycaemix attack
35
[TIA]: how does a Doppler USS work & what does it show
US wave bounce off RBCs.
Shows speed of flow.
36
[TIA]: ABCD2: Clinical features?
Unilateral weakness = 2pts
No weakness, speech disturbance = 1pt
37
[TIA]: ABCD2: Duration of symptoms?
>1hr = 2pts
1-59 mins = 1pt
