The following definitions are taken from the Canadian Stroke Best Practice website.
Primary Prevention is a population or an individual-based clinical approach directed toward preventing the initial occurrence of a disorder in otherwise healthy individuals. Primary prevention and health promotion recommendations related to stroke emphasize the importance of screening and monitoring patients at high risk for a first event. These include lifestyle and risk factor management, screening for hypertension & dyslipidemia, and the management of diabetes and atrial fibrillation.
Secondary Stroke Prevention is an individual-based clinical approach aimed at reducing the risk of a recurrent vascular event in individuals who have experienced a stroke, transient ischemic attack (TIA) or are at high risk due to their medical conditions or risk factors. Secondary prevention should be implemented throughout the recovery phase and can be addressed in acute care, stroke prevention clinics and community based settings.
In Ontario, a provincial working group was tasked with updating the model of care for Stroke Prevention Clinics. The following resources were developed and can be accessed here:
Canadian Stroke Best Practice Recommendations, 7th edition: acetylsalicylic acid for prevention of vascular events
A new Heart & Stroke guideline published March 23, 2020 in the Canadian Medical Association Journal does not recommend taking ASA (Acetylsalicylic acid) as a preventive measure for those who do not have a history of stroke or heart or vascular disease, a change to a decades-old common practice.
The recommendations are based on strong new research that indicates taking ASA (brand names include Aspirin, Entrophen, Novasen) daily could potentially do more harm than good for those at low risk for stroke, heart or vascular disease, by causing serious side effects such as internal bleeding.
