Madam Chair, committee members, on behalf of the Heart and Stroke Foundation, I'd like to thank you for the opportunity to appear before you to share our perspectives on chronic diseases related to aging. I'm Mike Sharma and I'm here as an expert representative of the Heart and Stroke Foundation. I'm a stroke neurologist and researcher, as well as a deputy director, clinical affairs, of the Canadian Stroke Network. Joining me is Manuel Arango, director of health policy at the foundation.
First and foremost, I'd like to express our gratitude to Parliament for a number of initiatives and commitments that will help reduce the impact of heart disease and stroke in Canada, including the recent adoption of new and improved tobacco package warnings, Bill C-32, which prohibits the use of certain flavourings in tobacco products and associated marketing; the commitment to implement defibrillators in hockey arenas across the country; and the commitment to include cardiovascular measures within the Canadian Partnership Against Cancer's longitudinal study of chronic disease known as the “Tomorrow Project”.
The Heart and Stroke Foundation is a national volunteer-based health charity founded over 50 years ago, with more than 130,000 volunteers and two million donors. We work to reduce heart disease and stroke by funding research, promoting healthy living to Canadians, and by working with all levels of government to inform and influence health policy.
We're aging. Every day 1,000 people in Canada turn 65, entering a stage of life with an increasing risk of stroke, heart disease, and dementia. The number of seniors in Canada is projected to increase from 4.2 million to 9.8 million between 2005 and 2036. Heart disease and stroke combined are the leading causes of death among Canadians 65 years of age and over, killing over 60,000 seniors annually. There are over 50,000 hospital admissions for stroke in Canada each year. That's one stroke every ten minutes. When you take into account that we don't hospitalize all strokes, the reality is that the number is much greater.
Those strokes that are hospitalized are called overt strokes, which produce acute traumatic symptoms. In addition to this, there are between five and ten times as many covert strokes. These are ones that do not produce acute manifestations but result in disability by other mechanisms. At a minimum, 300,000 Canadians are living with the effects of stroke today.
In view of the time constraints, we've chosen to focus on three main themes: stroke, aging, and economics; vascular disease of the brain and dementia; and, briefly, heart disease and aging.
In Canada, stroke is the leading cause of death and disability, costing $56,000 for the first six months of care alone. Estimated yearly costs are in excess of $5 billion. While 35% of individuals impacted by stroke are under the age of 65, age is the single strongest predictor of stroke occurrence. Stroke occurrence begins to rise at the age of 55, and doubles for each decade thereafter. Stroke results in physical, cognitive, and psychiatric dysfunction. Individuals have an impairment in their ability to make decisions, use language, think, and remember. Thirty percent are depressed at three months. Between one-third and two-thirds require rehabilitation for physical, cognitive, or communication difficulties. Fewer than 50% of individuals with stroke return to work, placing an additional burden on their caregivers and families.
In contrast to overt or large strokes, covert strokes cause functional impairment without producing overt symptoms or abrupt onset symptoms. We know that 95% of people age 65 and older show abnormalities in the brain related to disease of small blood vessels within the brain. Further, a quarter of healthy seniors aged 70 have evidence of small, silent strokes. Similar strokes are seen in 14% of Canadians aged 60. These small, silent strokes result in dementia, which in fact is a vascular disease.
Alzheimer's disease, which is often thought to be synonymous with dementia, rarely occurs alone. The vast majority of dementia consists of a combination of Alzheimer's disease and stroke, which goes by the term “mixed dementia”. By 2038, the number of Canadians with dementia will increase by a factor of 2.3, with regard to the 2008 level, which is to say, 1.1 million people. The lifetime risk for stroke or dementia in our country is one in two for women and one in three for men.
The increasing rate of obesity and diabetes, combined with aging of the population, will contribute to an increase in all forms of heart disease, including ischemic heart disease, heart failure, and cardiac arrhythmias. This will strain the health care system and have a major economic impact on the country. As an example, it is estimated that currently there are 500,000 Canadians living with heart failure and 50,000 new patients are diagnosed each year.
What can we do?
There are some changes to the health care system that will help. The Heart and Stroke Foundation is very proud to be part of the joint initiative known as the Canadian stroke strategy, a national initiative that is aimed at improving stroke care across Canada. The strategy has targeted the systematic implementation of best practices, thereby preventing stroke, minimizing damage when it occurs, and improving functional recovery.
In the upcoming health accord the federal government needs to ensure adequate transfer payments to the provinces in order to enable incorporation of the best practices from the Canadian stroke strategy, including the establishment of dedicated stroke units and improved rehabilitation and palliative care services for those living with chronic diseases.
Prevention is key. Prevention can help delay and compress chronic diseases in later life, saving money to the system and the economy and improving the quality of life. Prevention essentially is all about making the healthy choice the easy choice, creating environments that make it easy to live a healthy lifestyle.
Prevention of vascular disease requires addressing a number of risk factors, many of which can also contribute to cancer, diabetes, obesity, and other chronic illnesses. At a high level, prevention includes a healthy diet, physical activity, and avoidance of tobacco.
There are a number of potential measures to address these risk factors, but here are a few we believe we must act on now.
The brain and the heart are the primary targets of high blood pressure. High blood pressure can be prevented by healthy nutrition, especially by reductions in sodium consumption, and increased physical acitivity.
With respect to sodium consumption, the Heart and Stroke Foundation of Canada urges the federal government to act upon the recommendations of the sodium working group, who released their final report last July. In particular, we call upon the government to establish sodium reduction targets for the food industry, with an accompanying monitoring mechanism. These targets should reduce the average daily intake of salt to 2,300 miligrams by 2016. If these voluntary targets fail to produce desired outcomes, we support the implementation of regulations.
Reduction in trans-fat content in our diet is important. Trans-fat content in Canadian diets is much higher than international recommendations. We call upon the government to introduce trans-fat regulations.
Fruit and vegetable consumption is too low in this country and is getting more and more expensive for seniors living on limited budgets. The federal government should ensure that agricultural policy and subsidies facilitate the production and distribution of fresh, affordable fruit and vegetables.
Community design and infrastructure that supports active living is particularly important for older people who have conditions that make mobility more challenging. Appealing, accessible, and safe facilities for walking and cycling will make it easier for Canadians of all ages to enjoy physical activity. Also important is the provision of safe and attractive recreational facilities and parks.
We call upon the federal government to work with the provinces to establish an active transportation fund to provide long-term funding for municipal infrastructure that supports active transportation. We also urge the federal government to renew the very successful Canadian recreational infrastructure fund to ensure continued investment in recreational facilities and parks.
Tobacco is a hugely important risk factor. Smokers have strokes ten years earlier than non-smokers. It is critical that the government renew the federal tobacco control strategy and maintain the annual funding for this strategy at no less than its current funding level of $43 million per annum.
Acute treatment for strokes substantially reduces disability, but must be delivered very rapidly after stroke onset. The most common reason that these treatments are not delivered is delay. We urge the government to support public awareness campaigns that teach people to recognize the signs of stroke and respond appropriately.
Madam Chair, acting on these recommendations will help to reduce the impact of chronic diseases on our aging population and our economy.
Thank you for the opportunity to provide our perspective today before your committee.
