Learning Objectives Define 2 most common types of stroke. Identify the stroke continuum. List 4 modifiable stroke risk factors. Name 3 observable stroke signs or
symptoms. Describe reason for calling 9-1-1 for
stroke signs and symptoms. Articulate “door-to-needle” goal for tPA
administration.
Stroke: What is it?
Injury or death of brain tissue from oxygen deprivation.
A life threatening emergency.
Blood Supply to the BrainEach artery supplies blood to specific areas of the brain.
Stroke occurs when one of these arteries to the brain either is blocked or bursts.
Source: National Stroke Association
Transient Ischemic Attacks
Temporary blockage <24 hours duration.
Symptoms of numbness, trouble speaking, and loss of balance or coordination.
Increased risk of having stroke within 90 days.
Source: National Stroke Association
Ischemic Stroke Clot cuts off oxygen to a part
of the brain.
Most common stroke (80 – 85% of all strokes).
Types of Ischemic Strokes
Embolic A blood clot or
plaque fragment that forms in the body moving through the bloodstream to the brain.
ThromboticA blood clot thatdoes not travel butforms inside anartery supplyingblood to the brain.
Hemorrhagic Stroke Burst blood vessel in brain that
spills blood into brain tissue.
Accounts for about 15-20% of all strokes.
Types of Hemorrhagic Stroke
Intracerebral hemorrhage: Blood vessel bursts into the brain High blood pressure most common cause
Aneurysm: Weak spot on artery wall that balloons out,
forming a thin-walled bubble Leaks blood into or outside of the brain
Subarachnoid hemorrhage: Blood vessel bursts near surface of brain
pouring blood into area outside brain Increases pressure on brain
Facts About Stroke Stroke can happen at any time,
regardless of race, sex or age. Every 40 seconds someone in the US
has a stroke. Every 3-4 minutes, someone dies from
stroke. Two million brain cells die every minute
during stroke, increasing the risk of permanent brain damage, disability or death.
National Stroke Association
Facts About Stroke in Massachusetts
In 2007, stroke accounted for 5.1% (2,700) of all deaths and remains the third leading cause of death.
MA Vital Records 2007 In 2007, 2.4% of adults reported having
had a stroke.
MA BRFSS 2007 Over 17,000 patients are hospitalized
for stroke every year. MA Hospital Discharge Data 2004-2007
Disability Stroke is a leading cause of adult
disability in the US. With timely treatment, the risk of
death and disability from stroke can be lowered.
In 2010, stroke will cost the US $73.7 billion in health care services, medications, and lost productivity.

High Blood Pressure Overweight/Obesity Diabetes High Cholesterol Tobacco Exposure Excessive alcohol consumption Drug Abuse Atrial Fibrillation
High Blood Pressure High blood pressure – higher than 140/90. Approximately 30% of adults are unaware of
their high blood pressure. JNC-7
More than 40% of individuals with high blood pressure are not on treatment. JNC-7
2/3 of people with high blood pressure are not controlled to BP levels <140/90. JNC-7
26% of Massachusetts adults have high blood pressure. MA BRFSS 2007

Overweight and Obesity in Massachusetts
56.1% of adults are overweight or obese.
22% of adults are obese. 73% do not eat the recommended.
five or more servings of vegetables and fruits a day.
49% do not get regular physical activity.
MA BRFSS 2007
Diabetes In Massachusetts, 7.4% of adults have
been diagnosed with diabetes. MA BRFSS 2007
CDC estimates that an additional 2.2%
of Massachusetts adults don’t know that they have diabetes.
People with diabetes are two to four times more likely to have a stroke. National Stroke Association

High Cholesterol in MA
35.6% of MA adults have high cholesterol. MA BRFSS 2001-2007
The prevalence of high cholesterol has been increasing each year.
MA BRFSS 2001-2007
Low HDL cholesterol (the “good” kind) in men is a risk factor for stroke. American Stroke Association
TobaccoCigarette smoking
approximately doubles a person’s risk for stroke. CDC
In MA, the cities of Springfield, Fall River, New Bedford, Lowell, and Worcester have significantly higher rates of smoking than MA overall. MA BRFSS 2007
Excessive Alcohol Consumption
Chronic, excessive alcohol intake can precipitate hemorrhagic stroke:No more than 2 drinks per day for men
and no more than 1 drink per day for non-pregnant women. AHA
Most risk from excess alcohol intake is likely due to high blood pressure and impaired blood clotting mechanisms. National Stroke Association
Drug Abuse Use of cocaine, amphetamines,
and heroin associated with an increased risk of stroke.
Strokes caused by drug abuse are often seen in a younger population.
American Heart Association
Atrial Fibrillation Characterized by an irregular and
frequently fast heartbeat, atrial fibrillation (AFib) is the most common form of heart arrhythmia.
Associated with a five-fold increase in risk for stroke.
About 15% of people with strokes have Afib.
Increases the risk of death from stroke. National Stroke Association

Time Lost = Brain LostDelays in calling 9-1-1:
Most strokes are painless.Symptoms can be subtle.Person having a stroke may be unaware or unable to communicate.
Observers do not recognize it as a serious problem.
EMS Care is Critical
Identification of stroke by conducting stroke scale assessment.
Establish “last known well” time.Pre-notification to hospital to
activate stroke team.Transport to most appropriate
hospital for stroke care.

Primary Stroke Service (PSS) in MA
MDPH regulations passed by the state legislature in 2004.
Assure ambulances take patients to hospitals that can provide definitive care.
Improve coordination of care/pre-hospital care for persons experiencing stroke symptoms.
Primary Stroke Service (PSS) in MA
Assure hospitals have systems in place to accurately diagnose and treat, 24 hours per day, 7 days per week.
Assure data available to monitor system performance.
Emergency diagnostic and therapeutic services provided by a multidisciplinary team.
Stroke Treatment
Activase® (alteplase, recombinant, IV-tPA, tPA), was approved by the FDA for the treatment of acute ischemic stroke. IV-tPA is recommended for selected patients
within 3 hours of “last known well”. (Class I, LOE A)
IV-tPA should be administered to eligible patients within 3.0-4.5 hours of “last known well”. (Class I Recommendation, LOE B)
Adams, Stroke 2007
Meta-Analysis of the major IV tPA trials shows clear benefit up to 3 hrs and NOW beyond
Lancet, 2004; 363: 768–74
NINDS 12% ECASS3 7%
Door to Needle Time
The benefit of IV-tPA in stroke is strongly time dependent.
It is best right after symptom onset and declines steadily thereafter:1.9 million neurons lost per minute,For every 10 minute delay in tPA
delivery, 1 less patient improves. BAC/AHA/NIH recommendation: door to
needle time < 60 minutes. Only 27% of tPA patients at PSS hospitals
were treated within 60 minutes of arrival.
Impediments to tPA Use
Patient arrival at Emergency Department beyond 3-hour window.
Clinician acceptance of tPA due to risk of bleeding complications.
Institutional attitude and support related to the ability of medical systems to rapidly evaluate and treat stroke within the timeframe.
CDC’s Paul Coverdell National Acute Stroke Registry
Goal:to ensure that all Americans receive the highest quality of acute stroke care currently available and to reduce the number of untimely deaths attributable to stroke, prevent stroke-related disability, and prevent stroke patients from suffering recurrent strokes.
Get With The Guidelines (GWTG)-Stroke
Quality improvement for in-hospital acute care.
National program with over 1,600 hospitals and 1 million patient entries in registry.
Data management tool by Outcomes Science.
Stroke Performance Measures
In 2007, The Joint Commission, CDC, and the American Heart Association formed a Consensus Group to harmonize the stroke measures being collected by the three organizations. The result was the set of 10 consensus measures.
