MONDAY, Oct. 3 (HealthDay News) -- Compared to people who don't
smoke, smokers face twice the risk of stroke and they are likely to
have that stroke nearly a decade sooner, a Canadian study
But within two years of quitting smoking, the risk for stroke or
heart disease drops to non-smoker levels, the researchers said.
"Stroke is preventable," said Dr. Mike Sharma, deputy director of the Canadian Stroke Network (CSN), in a CSN news release. "This study highlights the sizable role smoking has on stroke. Quitting smoking, controlling blood pressure, following a healthy diet and being physically active significantly reduce the risk of stroke."
In conducting the study, to be presented Monday at the Canadian
Stroke Congress in Ottawa, researchers examined 982 stroke patients
over roughly two years. The researchers found the average age of
stroke victims who smoked was 58 -- nine years younger than the
average age of the non-smokers.
Smoking causes atherosclerosis, a buildup of plaque inside the
blood vessels, and increases the risk of blood clots. The study's
authors said smokers have double the risk of a stroke caused by a
dislodged blood clot (ischemic stroke) and four times the risk of a
stroke caused by a ruptured blood vessel (hemorrhagic stroke) than
people who don't smoke.
"The information from this study provides yet another important piece of evidence about the significance of helping people stop smoking," said study co-author Dr. Andrew Pipe of the University of Ottawa Heart Institute, in the news release. "It also alerts the neurology community to the importance of addressing smoking in stroke patients."
The study also showed smoking increases the risk for
complications from stroke and the likelihood of subsequent strokes.
To prevent this from happening, the researchers said several
initiatives are needed, including:
"It is critical for governments to continue to wage the battle against tobacco industry products," concluded Dr. Michael Hill, Heart and Stroke Foundation spokesperson, in the news release.
Because this study was presented at a medical meeting, the data
and conclusions should be viewed as preliminary until published in
a peer-reviewed journal.
The U.S. Centers for Disease Control and Prevention provides
more information on the
health effects of smoking.
