1. The document discusses guidelines and initiatives for treating acute ischemic stroke, including the importance of rapid treatment to minimize brain damage. 2. It describes the Hospital Kuala Lumpur Acute Ischemic Stroke Thrombolysis Initiatives (HASTE), which takes a multidisciplinary approach to treat stroke patients within 3 hours of onset to potentially reverse neurological impairment through thrombolytic reperfusion. 3. The HASTE program developed a critical pathway to rapidly identify, assess, and treat potential stroke patients from the emergency call through transport, the emergency department, and thrombolysis treatment.

2. Stroke Epidemiology
 3rd most common cause of death in developed countries, exceeded only
by coronary heart disease and cancer
 In Malaysia, top five leading causes of death with 8.43 per 100,000
population (MOH 2009)
 795,000 new or recurrent strokes occur per year in the US, accounting for
approximately 1 in 18 deaths
 The prevalence of stroke in the US is about 7 million (3.0%) at an
estimated cost in 2010 of 73.7 billion US-$
 In Europe, the incidence of stroke varies from 101.1 to 239.3 per 100,000
in men and 63.0 to 158.7 per 100,000 in women
 The estimated cost of stroke in Europe in 2010 was approx. € 64.1 billion
 In China, the prevalence of stroke ranges between 1.8% (rural areas) and
9.4% (urban areas)
 Worldwide, China has one of the highest rates of mortality (19.9% of all
deaths in China), along with Africa and parts of South America

9. AHA/ASA Guidelines
Recommendations on Emergency Systems
 Suspected acute stroke – be identified rapidly by dispatch
centres, which should dispatch the highest level of care
available in the shortest possible time
 EMS should briefly assess the patient on site (Class I, LOE B)
 EMS should begin initial stroke management in the field
(Class I, LOE B)
 Patients should be transported rapidly for evaluation and
treatment to the closest stroke facility (Class I, LOE B) and the
EMS should inform the ED prior to arrival
 Telemedicine can be an effective method to provide expert
stroke care to patients located in rural areas (Class IIA, LOE B)
 Pre-hospital providers, emergency physicians, and stroke
experts should collaborate to develop training, assessment and
transportation protocols

ED, emergency department

10. AHA/ASA Guidelines
Recommendations on Stroke Centres
 Creation of primary stroke centres is strongly
recommended (Class I, LOE B)
 Development of comprehensive stroke centres is
recommended (Class I, LOE C)
 Certification of stroke centres by an external body
(e.g. JCAHO) is encouraged (Class I, LOE B)
 Patients with suspected stroke should bypass
hospitals without stroke resources and go to the
closest facility capable of treating acute stroke
(Class I, LOE B)
Adams et al. Stroke 2007;38:1655-1711.
JCAHO, Joint Commission on the
Accreditation of Healthcare Organisations

11. AHA Guidelines for Cardiopulmonary Resuscitation and
Emergency CV Care
 Several studies a higher likelihood of good to excellent
functional outcome when rt-PA is administered to adult
patients with acute ischaemic stroke within 3 hours of
symptom onset
 Treatment of carefully selected patients with acute
ischaemic stroke with IV rt-PA between 3 and 4.5 hours
after onset of symptoms has also been shown to improve
clinical outcome, although the degree of clinical benefit is
smaller than that achieved with treatment within 3 hours
 Administration of IV rt-PA to patients with acute ischaemic
stroke who meet the NINDS or ECASS 3 eligibility criteria is
recommended if rt-PA is administered by physicians in
the setting of a clearly defined protocol, a
knowledgeable team, and institutional commitment
(Class I, LOE B) Jauch et al. Circulation 2010;122(suppl.3):S818-S828.

12. ESO Guidelines for the Management of Ischaemic
Stroke and Transient Ischaemic Attack
 In patients admitted within 3 hours of stroke onset brain CT
should be obtained to guide routine thrombolysis treatment
with rt-PA (Class I, Level A)
 I.V. rt-PA (0.9 mg/kg body weight, max. 90 mg), with 10% of
the dose given as a bolus followed by a 60-minute infusion,
is recommended within 4.5 hours of onset of ischaemic
stroke (Class I, Level A)
 The use of multimodal imaging may be useful for patient
selection for thrombolysis but is not recommended for
routine clinical practice (Class III, Level C)
ESO Guidelines 2009 Update. www.eso-stroke.org

13. ESO Guidelines: Recommendations for
Stroke Services and Stroke Units
 All stroke patients should be treated in a stroke unit (Class I,
Level A)
 Acute stroke patients should have access to high technology
medical and surgical stroke care when required (Class III,
Level B)
 The development of clinical networks, including
telemedicine, is recommended to expand access to high
technology specialist stroke care (Class II, Level B)
ESO Guidelines 2009 Update. www.eso-stroke.org

46. Actilyse®
Product Details

47. Actilyse®
 Actilyse®, rt-PA, is a serine protease, similar to
naturally occurring tissue plasminogen activator (t-PA)
 Mode of action
 With high affinity, Actilyse® binds to and activates
plasminogen attached to the fibrin netting of a blood clot
 Plasminogen is converted to plasmin, which catalyses the
breakdown of fibrin to its degradation products, resulting in
break up of the clot
 The affinity for freely circulating plasminogen is low, so
Actilyse® has highly effective local fibrinolytic effects and
relatively few systemic effects

51. Absolute contra indications for IV rt-PA -
cont
 Clinical presentation suggestive of SAH even if CT
Brain scan is normal.
 Presumed septic embolus.
 Patient has received heparin within the last 48 hours
and has elevated PTT or has a known hereditary or

increased risk of intracranial bleeding would outweigh
the potential benefits of treatment.
 Recent (within 30 days) biopsy of a parenchymal
organ or surgery that, in the opinion of the
responsible clinician, would increase the risk of
unmanageable bleeding.
 Recent (within 30 days) trauma with internal injuries
or ulcerative wounds.

54. Relative contraindications for IV rt-PA -
 GI or GU haemorrhage within the last 30 days or any

the responsible clinician, would increase the risk of
unmanageable bleeding.
 Arterial puncture at non compressible site within the
last 7 days.
 Concomitant serious, advanced or terminal illness or
any other condition that in the opinion of the
responsible clinician would pose a risk to treatment
