1 Scottish Hyperacute stroke Activity Register and Evaluation (SHARE) Peter Langhorne University of Glasgow

2 What’s in a name? S – Scottish H - Hyperacute A – Assessment and M - Management E - Evaluation

3 What’s in a name? S – Scottish H - Hyperacute I - Investigation and T - Treatment E - Evaluation

4 What’s in a name? S – Scottish H – Hyperacute stroke A – Activity R – Register and E - Evaluation

5 Stroke in Scotland Over 10,000 people have a new stroke each year 70,000 Scots living with consequences of a stroke Average lifetime cost of stroke £45,000 Good progress in developing services SSCA has help drive up standards

6 Before After Thrombolysis in acute stroke

7 In 2002, European Union regulatory authority approved rt-PA for stroke CONDITIONALLY Age In high quality stroke centres with stroke units with certain monitoring requirements Within 3 hours of an ischaemic stroke

8 Time is Brain Saver, Stroke Number making full recovery per 100 treated Impact of thrombolysis Time (hours) Benefit

9 Haemorrhage into an infarct

10 Saver, Stroke Number making full recovery per 100 treated Impact of thrombolysis Time (hours) Benefit Harm Time is Brain

11 Inclusion criteria Clinical symptoms and signs of definite acute stroke Clear time of onset Presentation within 3 hrs of acute onset Haemorrhage excluded by CT scan Age years old NIHSS less than 25 Consent to treat (every effort must be made to contact next of kin)

12 Rapidly improving or minor stroke symptoms Stroke or serious head injury 3 months Major surgery, obstetrical delivery, external heart massage last 14 days, Seizure at onset of stroke Prior stroke and concomitant diabetes Severe haemorrhage last 21/7 Increase bleeding risk History of central nervous damage (neoplasm, haemorrhage, aneurysm, spinal or intracranial surgery or haemorrhagic retinopathy) Symptoms suggestive of SAH (even if CT is normal) *Blood pressure above 185 mmHg systolic or 110 mmHg diastolic Known clotting disorder Patient on heparin or warfarin Suspected iron deficient anaemia or thrombocytopenia Suspected hypoglycaemia or hyper glycaemia >3 mmol/l > 22 mmol/l Bacterial endocarditis, pericarditis Acute pancreatitis Premorbid dependency Ulcerative GI disease last 3 months, oesophageal varices, arterial-aneurysm, arterial/venous malformation. Severe liver disease including cirrhosis, acute hepatitis Neoplasm with increased bleeding risk Large hypodensity on CT scan (use ASPECTS* scoring if time permits; otherwise use the 1/3 of MCA territory rule) Symptoms suggestive of SAH (even if CT is normal) *Blood pressure above 185 mmHg systolic or 110 mmHg diastolic Known clotting disorder Patient on heparin or warfarin Suspected iron deficient anaemia or thrombocytopenia Suspected hypoglycaemia or hyper glycaemia >3 mmol/l > 22 mmol/l Bacterial endocarditis, pericarditis Acute pancreatitis Premorbid dependency Ulcerative GI disease last 3 months, oesophageal varices, arterial-aneurysm, arterial/venous malformation. Exclusion criteria

13 Low density loss of grey/white definition loss of insula loss of basal ganglia Swelling loss of sulci effacement of ventricles Hyperdense artery Farrall, Kane, Wardlaw

14 Conditions Acute stroke unit Under the care of stroke physician or neurologist Monitored bed Nurses trained in thrombolysis & acute skills Protocols & guidelines for care Access to immediate imaging (24hrs)

15 CT head scanning availability

16 Hyperacute stroke specialist teams

17 Patient has Video Consultation with the consultant following viewing of CT brain image -

18 Network of acute sites (with CT scanning) and stroke specialists
