Ages Eligible for Study:   18 Years to 75 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patient aged 18 years and over followed at the Montreal Heart Institute's Anticoagulation clinic
  • Warfarin treatment planned for at least 4 months after inclusion in the study
  • Warfarin treatment initiated for at least 6 months
  • Last 2 INRs between 1.5 and 4 if target INR is between 2 and 3
  • Last 2 INRS between 2 and 4 if target INR is between 2.5 and 3.5
  • Provide a signed informed consent

Exclusion Criteria:

  • Patient unable to understand (spoken and written) French or English
  • Patient refuses or is unable to attend the required training sessions
  • Targeted INR other than 2 to 3 or 2.5 to 3.5
  • Handicap or physical limitation compromising the patient's ability to initiate self-monitoring in the absence of a proxy helper
  • Moderate to severe cognitive impairment or important comprehension problems
  • Active neoplasm

  • Recent major bleeding (less than 3 months before inclusion)
  • Stroke, acute coronary syndrome, percutaneous coronary intervention, coronary artery bypass graft, cardiac valve replacement, deep veinous thrombosis or pulmonary embolism in the 3 months prior to inclusion
  • Any other condition that, in the opinion of the investigators, of the treating physician or of the healthcare professionals working at the anticoagulation clinic could make self-management by the patient impossible
