Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Exercise Limitation [ Time Frame: 1 month ]
    Exercise limitation will be assessed by VO2 max (% predicted) on cardiopulmonary exercise testing (CPET)

  2. Exercise Limitation [ Time Frame: 12 months ]
    Exercise limitation will be assessed by VO2 max (% predicted) on cardiopulmonary exercise testing (CPET)


Secondary Outcome Measures :
  1. Quality of Life [ Time Frame: Baseline ]
    Quality of Life will be assessed using the SF-36v2 questionnaire.

  2. Quality of Life [ Time Frame: 1 month ]
    Quality of Life will be assessed using the SF-36v2 questionnaire.

  3. Quality of Life [ Time Frame: 3 months ]
    Quality of Life will be assessed using the SF-36v2 questionnaire.

  4. Quality of Life [ Time Frame: 6 months ]
    Quality of Life will be assessed using the SF-36v2 questionnaire.

  5. Quality of Life [ Time Frame: 12 months ]
    Quality of Life will be assessed using the SF-36v2 questionnaire.

  6. Respiratory Disease-Specific Measures [ Time Frame: Baseline ]
    Respiratory Disease-Specific measures will be assessed using the Pulmonary Embolism Quality of Life Questionnaire (PEmb-QOL) and the San Diego Shortness of Breath Questionnaire (SOBQ).

  7. Respiratory Disease-Specific Measures [ Time Frame: 1 month ]
    Respiratory Disease-Specific measures will be assessed using the Pulmonary Embolism Quality of Life Questionnaire (PEmb-QOL) and the San Diego Shortness of Breath Questionnaire (SOBQ).

  8. Respiratory Disease-Specific Measures [ Time Frame: 3 months ]
    Respiratory Disease-Specific measures will be assessed using the Pulmonary Embolism Quality of Life Questionnaire (PEmb-QOL) and the San Diego Shortness of Breath Questionnaire (SOBQ).

  9. Respiratory Disease-Specific Measures [ Time Frame: 6 months ]
    Respiratory Disease-Specific measures will be assessed using the Pulmonary Embolism Quality of Life Questionnaire (PEmb-QOL) and the San Diego Shortness of Breath Questionnaire (SOBQ).

  10. Respiratory Disease-Specific Measures [ Time Frame: 12 months ]
    Respiratory Disease-Specific measures will be assessed using the Pulmonary Embolism Quality of Life Questionnaire (PEmb-QOL) and the San Diego Shortness of Breath Questionnaire (SOBQ).

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
Patients seen in the Emergency Department, in-patient wards, out-patient clinics or anticoagulation clinics.
Criteria

Inclusion Criteria:

  1. First episode of acute symptomatic PE that was objectively diagnosed* within last 10 days
  2. Treated with anticoagulants

  3. ≥ 18 years old

    • PE will be diagnosed if there is a high probability V/Q scan (as per PIOPED Study criteria 66), an intraluminal filling defect in segmental or larger vessels on CTPA or a constant intraluminal filling defect or abrupt cut-off of vessels greater than 2.5 mm diameter on pulmonary angiography 8,10. Patients with non-definitive test results (e.g. low or intermediate probability V/Q scan, subsegmental PE on CTPA (~5% of PE patients 12) will not be included in order to have a strictly defined population of patients with definite PE.

Exclusion Criteria:

  1. Contraindication or unable to perform CPET or 6MWT (amputated or paralyzed limb(s), severe lower extremity arthritis, preexisting cardiopulmonary condition precluding exercise including unstable angina or myocardial infarction in last 6 weeks, uncontrolled hypertension, serious cardiac dysrhythmia on resting EKG [severe bradycardia or tachycardia, sick sinus syndrome or multifocal premature ventricular contractions] and syncope)
  2. Contraindication to CTPA (allergy to iodinated contrast, CrCl or eGFR < 30 ml/min)
  3. Severe comorbidity (congestive heart failure [LVEF < 35%], severe COPD or restrictive lung disease [FEV1<50%, chronic need for oxygen therapy])
  4. Previous DVT (as ~40% of patients with proximal DVT have asymptomatic PE on lung imaging 67)
  5. Life expectancy < 1 year (e.g. active or terminal cancer, end-stage cardiac or respiratory disease).
  6. Pregnancy or lactation
  7. Unable to read questionnaire in English or French
  8. Unable to return to study centre for required follow-up visits
  9. Unable or unwilling to provide written informed consent
