Q

What is TIA

A

Transient ischaemic attack- same as stroke but lasts less than 24hours

3
Q

Why is a CT scan needed on admission for someone with suspected stroke

A

Distinguish between haemorrhagic and ischaemic stroke

4
Q

Two types of stroke?

A

Ischaemic

Haemorrhagic

5
Q

What causes ischaemic stroke

A

Atherosclerosis plaques rupture, form embolus/thrombus and travel to brain as block blood supply

6
Q

A

Rupture bleed on brain

From aneurysm

7
Q

Strategies for preventing stroke

A
Reduce BP 
Reduce cholesterol 
Stop smoking 
Diabetes control 
AF identification
8
Q

What does the ABCD score predict and what does it stand for

A
Predicts risk of stroke after TIA
A= age >60 
B= BP SBP>140 or DBP>90
C=clinical features: 
-unilateral weakness (2)
-speech disturbances without weakness (1) 
D= duration of symptoms:
->60mins (2) 
-10-59 mins (1) 
-<10 mins (0) 
 diabetes= 1 point
9
Q

What anticoagulation would you offer a patient with AF

A

Warfarin
Apixaban
Dabigatran
Rivaroxaban

A

Scoring system used to calculate the risk of a patient with AF having a stroke

14
Q

What does CHA2DA2VASc score stand for and what’s the points

A
C= CHF (1) 
H=hypertension (1)
A= age (>75=2) 
D= diabetes (1) 
S= stroke/TIA history (2) 
V=vascular disease (1) 
A= age (65-74=1) 
S= sex (female=1)
15
Q

When do you offer rate or rhythm control in AF

A

Rate is first line except in people:

  • whose AF is reversible
  • heart failure due to AF
  • new onset AF
  • with atrial flutter suitable for ablation strategy
  • rhythm control more suitable
16
Q

When do you offer rhythm control in AF?

A

When AF symptoms continue after heart rate has been controlled or for whom rate-control strategy has not been successful

17
Q

List symptoms of AF

A
Palpitations 
Dyspnea
Chest pain 
Light headedness
Syncope
