minimize stroke’s effects

To benefit from new stroke drugs, getting to the emergency room
immediately after a stroke is essential
In the United States, on average, someone suffers a stroke every 53
seconds. Every 3.3 minutes someone dies from stroke, also called brain
attack or cerebrovascular occlusion. Not all victims of stroke are
senior citizens. Of the 600,000 stroke victims each year, 28 percent are
under the age of 65.
The most common form of stroke, called ischemic stroke, occurs when a
blood vessel in the brain becomes clogged with fat or cholesterol
(cerebral thrombosis) or a blood clot (cerebral embolism). Brain cells
are starved of life-supporting oxygen and begin to die. Various body
functions die with them, from speech to vision. Ischemic strokes account
for 85 percent of all strokes.
In the US, 4.4 million stroke victims are alive today. One of them,
someone you wouldn’t think could have had a stroke, is 36 year old
Cortez Lancaster. He discovered one morning that he couldn’t move his
hand: “It feels like my whole body’s not working properly. It’s
harder now for me to get dressed, to button my clothes. A lot of stuff I
have to compensate for like my shoes. I can’t buy laced up tennis
shoes.”

paralyzed
There’s a chance Cortez could have avoided the debilitating effects
of stroke had he been treated immediately after his stroke began with a
pharmacological breakthrough of the nineties, a drug called Tissue
Plasminogen Activator (t-PA). The medication, tested
in the early 1990’s and released in 1996, breaks up blood clots.
These so-called thrombolytic agents stop artery blockage in the brain,
saving brain nerve damage and related functions. t-PA, which is only for
ischemic stroke, not hemorrhagic stroke, is only highly effective if
administered promptly and appropriately, that is, within three hours of
a stroke or the onset of stroke symptoms. Stoke sufferers who are given
t-PA properly are thirty percent more likely to have little or no
disability compared to patients who do not receive t-PA.
The tight time frame for the drug’s effectiveness, and lack of
awareness about the drug, are limiting its benefits to just a small
percentage of the millions of stroke victims who need it. In the next
few years an American Heart Association campaign called “Operation
Stroke... Chain of Recovery” will educate emergency personnel and the
general public about the significant benefits of Tissue Plasminogen
Activator.
Dennis Landis, MD, Chief of Neurology, University Hospitals of
Cleveland, says too few know about this remarkable stroke therapy: “It
is such an obviously good therapy that we thought it would be taken
advantage of and made available across the country. That has not
happened. It’s discouraging. The estimates are that now between only
one and two percent of people who could benefit from this therapy in
fact receive it.”
Stroke-trained hospital staff can identify, test, and treat stroke
victims with appropriate urgency.
Anthony Furlan, MD, Director, Cerebrovascular Center, Cleveland
Clinic, says timing is paramount for t-PA’s benefits: “The patients
just don’t get to the hospital on time. t-PA has to be given within
three hours of stroke onset, so by the time the patient recognizes
they’ve had a stroke, calls 911, gets to a hospital, [does] all the
things that have to be done in the hospital, sees the doctor, gets a CAT
scan... three hours may have evaporated.”
Sponsors of “Operation Stroke... Chain of Recovery” believe
hospitals need to orient and organize for treating stroke with t-PA.
There are treatment risks, specifically a six percent chance of brain
hemorrhage, so doctors need to be trained to select only suitable
patients. Education and preparedness are the keys. Dr. Furlan thinks too
few hospitals have a stroke plan, the way they do for heart attacks:
“This doesn’t just happen. Your systems have to be in place, they
have to be organized. I mean we run into things like the elevator is not
available and the patients can’t get to the CAT scanner on time and
for a reason like that they can’t get t-PA.”
Money is not a factor with t-PA treatment: the drug is relatively
inexpensive. It can save huge costs later, bills that people like Cortez
Lancaster face in rehabilitation. According to the American Heart
Association, stroke costs add up to $40 billion a year in health care
and lost productivity. An average hospital bill for stroke is around
$18,000.
As for the rush to administer t-PA, the clock starts ticking with the
response of the stroke victim to the initial symptoms of stroke. In the
quest to reduce cardiovascular disease by 25 percent by 2008, the
American Heart Association is stepping up its efforts to educate the
public on the warning signs of stroke and mini-strokes called TIA’s,
transient ischemic attacks. The aim is to provide the best care
available with minimum delay.
