Prevention focuses on the avoidance of the incidence of a transient ischemic attack or a stroke. There are three components to prevention: Health Promotion, Primary Prevention, and Secondary Prevention.
The Southwestern Ontario Stroke Network supports stroke prevention through collaboration with stakeholders, offering education opportunities, the development of resources and tools, and through Secondary Stroke Prevention Clinics.
- Up to 80% of strokes are preventable
- 90% of Canadians have at least one stroke risk factor
- Most stroke risk factors are modifiable, or within your control
- Atrial Fibrillation increases the risk of stroke by 5x
- Smoking increases the risk of stroke by 4x
- Your risk of stroke is greater if you or an immediate family member has had a stroke or TIA
- People of Southeast Asian, Latin American, African-Canadian, or Aboriginal descent are at higher risk of stroke
- The risk of stroke doubles every 10 years for those aged 55 and older
- Stroke can occur at any age
The Southwestern Ontario Stroke Network will collaborate with different public health partners on initiatives. The Ontario Stroke Network has developed health promotion resources and tools related to stroke.
Primary prevention recommendations related to individual stroke risk factors emphasize the importance of screening and monitoring those patients at high risk of a first stroke event. It is usually implemented in the primary care setting with a family physician or nurse practitioner.
The Southwestern Ontario Stroke Network promotes primary prevention through physician education sessions and the development of tools and resources.
Secondary stroke prevention can be addressed by hospitals, secondary stroke prevention clinics, family physicians/nurse practitioner, and community-based care programs. Secondary prevention issues should be regularly addressed on an ongoing basis following a stroke or TIA.
The Southwestern Ontario Stroke Network supports secondary stroke prevention through:
- Specialized, rapid-access, Secondary Stroke Prevention Clinics
- Carotid revascularization surgery, available in two centres within the region
- Creation of clinical resources and tools
- Education sessions and workshops, including those targeting physicians
The Ontario Stroke Network promotes secondary stroke prevention through provincial stroke rounds and the development of tools to guide clinical practice.
