This Secondary Prevention of Stroke module focuses on management of recurrent stroke risk reduction in patients who have experienced an initial stroke or transient ischemic attack. In some cases, this module will also guide healthcare providers with guidance for individuals at high risk of a stroke or transient ischemic attack based on current health status and the significant presence of one or more vascular risk factors.
Primary prevention and the reduction of risk factor prevalence in the general population are not the main focus of the Canadian Stroke Best Practice Recommendations; therefore, only selected recommendations related to primary prevention are included. A comprehensive set of recommendations for primary prevention are available in existing high quality guidelines developed by other organizations (such as Canadian Cardiovascular Society, Hypertension Canada Blood Pressure guidelines, Canadian Task Force on Preventative Health Care, and the Canadian Physical Activity Guidelines).
The 2020 update of the Canadian Stroke Best Practice Recommendations Secondary Prevention of Stroke module reinforces the growing and changing body of research evidence available to guide stroke prevention services. A coordinated and organized approach to assessment and aggressive risk factor management is emphasized throughout this module.
The Canadian Stroke Best Practice Recommendations (CSBPR) Secondary Prevention of Stroke 2020 Seventh Edition module supersedes all recommendations contained in the CSBPR Secondary Prevention of Stroke 2017 Sixth Edition module.
Highlights of significant updates and new additions to the Secondary Prevention of Stroke best practice recommendations for 2020 that are based on new and emerging evidence include:
- New simplified triage recommendations for patients with acute transient ischemic attack and minor strokes
- Updated recommendations regarding the diagnostic workup of patients with ischemic stroke or transient ischemic attack (imaging, echocardiography for PFO detection, pulse palpation for opportunistic atrial fibrillation screening, and thrombophilia testing)
- New section on perioperative management of anticoagulant and antiplatelet therapy
- New recommendation regarding the ESUS treatment trials (embolic strokes of undetermined source)
- Updated recommendation regarding the duration of dual antiplatelet therapy after transient ischemic attack or minor stroke
- New recommendation regarding the THALES trial treatment regimen
- New recommendation regarding permissive hypertension in patients experiencing hemodynamic ischemia related to critical stenosis of an extracranial or intracranial artery.
- New recommendation regarding vertebral artery stenting
- Updated recommendations regarding management of patients with atrial fibrillation
- Updated recommendations regarding management of patients with patent foramen ovale
- Update recommendations regarding cervicocephalic artery dissection.
- New recommendation on PCSK9 inhibitor therapy for lipid management
- New recommendation regarding patients with cancer-associated stroke
- New recommendation regarding influenza vaccination and cautions related to air pollution.
- Recommendations on virtual care for delivery of secondary stroke prevention
In addition, there are emerging trends in stroke prevention research that have been reviewed and discussed by the writing group. These are areas that the group felt were important to monitor but the evidence is not sufficiently clear enough at the time of publication of these guidelines to make specific recommendation statements. These areas include genetic prediSPoSition and biomarkers (e.g., ACE2), and Transcranial Doppler.
The detailed methodology and explanations for each of these steps in the development and dissemination of the CSBPR is available in the Canadian Stroke Best Practice Recommendations Overview and Methodology manual available on the Canadian stroke best practices website at https://www.strokebestpractices.ca/recommendations/overview-methods-and-knowledge-exchange.
Management of Conflicts of Interest within CSBPR: All potential participants in the recommendation development and review process are required to sign confidentiality agreements and to declare all actual and potential conflicts of interest in writing prior to participation. Any conflicts of interest that are declared are reviewed by the Chairs of the CSBPR Advisory Committee and appropriate Heart & Stroke staff members for their potential impact. Potential members of any writing group who have conflicts that are considered to be significant with respect to the topics within the module of interest are not selected for writing group or reviewer roles. Participants who have conflicts for one particular topic area are identified at the beginning of discussions for that topic and are recused from voting. If the persons in conflict are one of the cochairs then they are recused from chair responsibilities for that discussion, and another non-conflicted participant assumes the chair role for that discussion and voting to ensure balanced and unbiased discussions. Heart & Stroke senior staff members, who do not have any conflicts of interest, participate in all writing group discussions, and will intervene if there is any perceived untoward bias by a writing group member. Declarations of Conflict of interest for writing group members can be found in Appendix One.
