Canadian Task Force on Preventive Health Care

Summary Table of Recommendations

Please note: In 2003, the CTF updated its Grades of Recommendations to include an "I Recommendation" for situations where insufficient evidence exists to allow a recommendation to be made.  (Formerly, these situations were captured under a "C Recommendation".)  This change is not retroactive, and all "C Recommendations" made prior to 2003 have not been reevaluated in light of the new "I" recommendation grade.  For a discussion of these recommendation grades, please link to the 2003 article in the Canadian Medical Association Journal here.

Preventive Health Care, 1999 Update: Use Of Ambulatory Electrocardiography For The Detection Of Paroxysmal Atrial Fibrillation In Patients With Stroke

Prepared by Chaim Bell, MD, Dept. of Medicine, University of Toronto, Institute of Medical Science, and Moira Kapral, MD, Department of Medicine, University of Toronto, Division of General Internal Medicine and Clinical Epidemiology, The Toronto Hospital

These recommendations were finalized by the Task Force in June 1999


 
MANEUVER EFFECTIVENESS LEVEL OF EVIDENCE <REF> RECOMMENDATION
Ambulatory ECG The maneuver is safe but little is know about its sensitivity and specificity Descriptive studies <36-39> (III)
All patients presenting with stroke or transient ischemic attack Detection of atrial fibrillation over initial ECG is 2.3% - 5.4% Cohort and case-control studies <46-52> (II-2) There is insufficient evidence to recommend for or against ambulatory ECG screening for patients presenting with stroke or transient ischemic attack (C)
Anticoagulation if atrial fibrillation detected after stroke
Patients with paroxysmal atrial fibrillation Unknown 25% of patients in large randomized controlled trial <19> (I) (no subgroup data provided) There is fair evidence to generalize from chronic atrial fibrillation data and expert opinion to recommend therapy with warfarin (B)*

*While direct evidence is lacking, anticoagulation should be strongly considered.
