5 Multiple choice questions

  1. - chronic infectious disease
    - uncontrolled metabolic disease
    - hypertrophic cardiomyopathy
  2. - greatest when pre-test likelihood is intermediate to high probability of CAD
    - Little value in testing individuals who are asymptomatic
  3. - Diagnosis - do they have CVD (most used)
    - Disease severity and prognosis in patients w/ CAD
    - Evaluation of medical therapy
    - Stratify patients for further medical intervention (e.g. determine if person is good patient for heart transplant)
    - Functional capacity for activity counseling and exe program
  4. 1) Determine # of ppl in population w/ disease
    2) Determine # w/ disease that will have '+' testing (# w/ disease x 0.7)
    3) Determine # w/ disease that will have '-' test (Total diseased # - # w/ '+' test)
    4) Do the same for those w/o disease
  5. - treadmill
    - leg ergometer
    - arm ergometer

5 True/False questions

  1. Describe the sensitivity, specificity of exercise testing diagnostics with ECG. What is a better method?1) Sensitivity - % of persons test who have CAD and show positive test
    2) Specificity - % of persons test that don't have CAD and show negative test
    3) Predictive Value - how accurately a test result correctly identifies a presence or absence of CAD
    4) Positive predication value - % of subjects w/ a positive test that have CAD
    5) Negative predicted value - % subjects w/ negative who don't have CAD

          

  2. What is pretest likelihood?- likelihood that diagnostic test will lead to a positive CAD diagnosis

          

  3. List some indicators for stopping an ETT.- treadmill
    - leg ergometer
    - arm ergometer

          

  4. What is the formula used to determine positive predictive value and negative predictive value1) Determine # of ppl in population w/ disease
    2) Determine # w/ disease that will have '+' testing (# w/ disease x 0.7)
    3) Determine # w/ disease that will have '-' test (Total diseased # - # w/ '+' test)
    4) Do the same for those w/o disease

          

  5. List some exercise test and describe who they're appropriate forBruce or Ellestad:
    - good for young ppl b/c the between-stage graduations of grade and speed are more aggresive
    USAFSAM or Naughton
    - Food for older ppl b/c more gradual between-stage progressions of grade and speed
