Stroke Flashcards
what should a patient be given immediately if you suspect that they are having a transient ischaemic attack (TIA)
aspirin 300mg until diagnosis confirmed
if intolerant to aspirin: add PPI, if still intolerant use an antiplatelet drug
what is the initial management of ischaemic stroke
- Alteplase within 4.5 hrs (+ intracranial haemorrhage excluded)
- Aspirin 300 mg once daily for 14 days, started as soon as possible within 24 hours of symptom onset
- note: if pt intolerant to aspirin, can give aspirin + PPI or an alternative antiplatelet*
when is Alteplase given in the initial management of ischaemic stroke
it should be given if:
- it can be administered within 4.5 hrs of of symptoms onset
AND - imaging techniques (e.g MRI) show patient does not have an intracranial haemorrhage
what is not recommended for treatment of stroke in patients with sinus rhythm
do not give anticoagulants as an alternative to antiplatelet drugs
when may the use of parenteral anticoagulants be consider in the treatment of stroke
only when the patient has symptoms of deep vein thrombosis/ pulmonary embolism or if they are at high risk of developing DVT/ pulmonary embolism
what drug should NOT be given in the acute phase of ischaemic stroke
warfarin
which patients should take 300mg aspirin for 2 weeks in the acute phase of ischaemic stroke
patients with:
- disabling ischaemic stroke
- atrial fibrillation
describe the long-term management of transient ischaemic stroke (TIA) and ischaemic stroke in patients who do not have AF
- start long term treatment with clopidogrel 75mg OD. if not tolerated, other options are :
- modified-release dipyridamole (200mg BD) + aspirin 75mg OD
- modified-release dipyridamole alone (if aspirin + clopidogrel both not tolerated )
- aspirin alone (if modified-release dipyridamole + clopidogrel both not tolerated)
note: dose of modified-release dipyridamole =200mg BD, aspirin= 75mg OD
TRUE OR FALSE
anticoagulants are routinely recommended for the long term prevention of stroke
FALSE
anticoagulants are NOT routinely recommended for long-term prevention of recurrent stroke. They are only used if a patient with AF has had a stroke
what the only exceptions in which you would use anticoagulants in the long-term prevention of stroke
if the patient has atrial fibrillation or other conditions such as: cardiac source of embolism, cerebral venous thrombosis or arterial dissection
when would you start a patient on high intensity statins after a transient ischaemic stroke (TIA) and ischaemic stroke
- high intensity statin (e.g atorvastatin) should be started within 48 hours after the onset of stroke symptoms irrespective of the patient’s serum-cholesterol concentration
- if patient already taking statins, then continue treatment with statins
TRUE OR FALSE
A patient’s serum-cholesterol concentration is considered when deciding if they should start high intensity statins after a stroke
FALSE.
ALL patients are started on a high intensity statin (e.g atorvastatin) within 48 hours of stroke symptoms starting. This is irrespective of their serum-cholesterol concentration
note this includes all stroke patients unless they have had a intracerebral haemorrhage
what is the target blood pressure for patients after a stroke
<130/80 mmhg
which drug class should not be used in the treatment for hypertension after a stroke
beta-blockers should not be used for hypertension treatment after a stroke. Only use them if they are indicated for a coexisting condition
what are the treatment options if a patient has intracerebral haemorrhage following a stroke
- surgery may be needed to remove hematoma (collection of blood within skull) and relieve intracranial pressure
- give rapid blood pressure lowering therapy within 6 hours
