Acute Stroke: Principles of Modern

Management

A program of the American Academy of Neurology

The AAN Acute Stroke Management courses are supported in part by unrestricted educational grants from Abbott Laboratories, Genentech,

Inc., Janssen Pharmaceutical, and Wyeth-Ayerst Pharmaceutica .

Overview of the Course

GOALS OF THE COURSE

• Review management of patients with acute stroke.

 Diagnosis

 Treatment of ischemic stroke

 Treatment of hemorrhagic stroke

• Review in-hospital management.

• Review management to prevent stroke or recurrent stroke.

STROKE FACTS

• Third leading cause of death in the United

States

• Common cause of disability and long-term institutionalized care

• Economic consequences more than $40 billion annually

• Affects not only the patient but the entire family

STROKE AS A

PUBLIC HEALTH PROBLEM

• WHO – increased importance of stroke during next 50 years

 Developing countries

 Industrial societies including U.S.

• Decline in stroke incidence to be reversed

• Increase due to aging of population

• People who survive severe heart disease at high risk

STROKE EPIDEMIOLOGY

• Advancing age is the premier predictor of stroke

– Stroke is an important cause of death in children

– Strokes are relatively common in young adults

• More women die from stroke than do men

• More women die from stroke than from cancer of breast

• Stroke accounts for 10% of maternal deaths during pregnancy or the peripartum period

• Under the age of 45, more women die from stroke than from heart attack

• Approximately 60% of patients with SAH are women

• Atrial fibrillation is an important risk factor for stroke among women older than 75

SUBTYPES OF STROKE

• HEMORRHAGIC STROKE – 20% of cases

– Subarachnoid hemorrhage

– Intracerebral hemorrhage

• ISCHEMIC STROKE – 80% of cases

– Large artery atherosclerosis

– Cardioembolism

– Small artery occlusion (lacunes)

– Non-atherosclerotic vasculopathies

– Hypercoagulable state

CURRENT STRATEGIES

MANAGEMENT OF CEREBROVASCLAR DISEASE

• Treatment of risk factors in large populations

• Treatment of highest risk persons

• Management of acute stroke

• Prevention and treatment of medical and neurological complications

• Rehabilitation

• Prevention of recurrent stroke

TREATABLE RISK FACTORS IN

PREVENTION OF STROKE

• Hypertension

• Smoking

• Hypercholesterolemia

• Hyperhomocysteinemia

• Diabetes mellitus

• Alcohol abuse

• Drug abuse

• Co-developing heart disease

ANTITHROMBOTIC THERAPIES

TO PREVENT ISCHEMIC

STROKE

• Oral anticoagulants

• Antiplatelet agents

– Aspirin

– Aspirin and dipyridamole

– Clopidogrel

– Ticlopidine

SURGICAL MEASURES TO

PREVENT ISCHEMIC STROKE

• Carotid endarterectomy

• Extracranial/intracranial bypass

• Other reconstructive operations

• Angioplasty and stenting

• Cardiovascular operations

IMPORTANCE OF ACUTE

MANAGEMENT OF STROKE

• Medical and surgical interventions lower risk of stroke, but they do not eliminate stroke entirely

• Some patients have a stroke as their first symptom

• Some causes of stroke are not amenable to preventive therapies

BRAIN ATTACK

• The causes and effects of acute stroke (brain attack) are similar to those that cause acute myocardial ischemia (heart attack)

• Secondary to arterial diseases and lifethreatening

• Potential for serious medical or neurological complications

• Mandate emergent interventions to limit effects

• Can be treated successfully and improving outcomes

TIME IS BRAIN

Components of Modern Management

 Prompt recognition

 Call 911 or seek attention

 Speedy transport (EMS)

 Rapid evaluation

 Urgent treatment

Pre and Post Course

Self Assessment

Goal: To assess patterns of physician behavior change as a result of attending the AAN Acute Stroke Management Course.

This goal will be achieved by measurement of knowledge at the following intervals: at the beginning of the course; at the end of the course; six months after the course.

1.

Pre Course Self Assessment

• 8:40 AM – 9:00 AM

Complete pre course self assessment

AAN staff will pick-up

2.

Post Course Self Assessment

• 4:10 PM – 4:30 PM

Complete post course self assessment

AAN staff will pick-up

3.

Six-month follow-up

• Assessment tool sent to all participants 6 months after the course
