Smoking is a major cause of strokes.1,2 Smokers are four times more likely to have a stroke compared with non-smokers.3 This risk is particularly elevated in younger people.2 Non-smokers living with smokers are also more likely to suffer a stroke.3
A stroke occurs when a blood vessel that supplies blood to the brain suddenly becomes blocked (ischaemic stroke) or bleeds (haemorrhagic stroke).4 This results in part of the brain dying and causes loss of function of that part of the brain. A stroke may lead to death or affect functions such as movement of body parts, vision, swallowing and communication.4,5
Ischaemic strokes are generally as a result of atherosclerosis in the carotid arteries and their branches.6 Atherosclerosis occurs when there is a narrowing and clogging of the arteries which reduces blood supply, and the amount of oxygen available, throughout the body.7 Smoking cigarettes is known to contribute to the development of atherosclerosis. The more cigarettes you smoke the greater the development of carotid artery atherosclerosis8 and the higher the risk of having a stroke.9
Some people experience a transient ischaemic attack (TIA) before a stroke. TIA's are sometimes called 'mini-strokes' and are important predictors of stroke.4,5 A TIA produces temporary stroke-like symptoms that leaves no residual signs. One in three people who have had a TIA will go on to have a stroke and another one in three will have repeated TIAs.4,5
Stroke is the second largest single cause of death in Australia. In 2004, 12,041 people died (9.1% of all deaths) as a result of stroke.10 There are approximately 40,000 – 48,000 stroke events among Australians each year4,5 and approximately a third of people will die within a year of having a stroke.5,11
In 2003 there were approximately 346,700 Australians who had suffered a stroke at some time. Of these, 282,600 had a disability.4
Your risk of stroke decreases after quitting. Between five and 15 years after quitting your risk of having a stroke is the same as a non-smoker.7
