Ch 18 Exercise and CHD

  1. An accumulation of lipid deposits in large and medium sized arteries.
  2. In Arterosclerosis is it true that eventually blood flow is impeded?
  3. When in life does arterosclerosis start?
    early in life
  4. T/F
    Arterosclerosis may involve damage to endothelial cells and LDL particles are deposited at damages sites.
  5. Blockages in arteries

    Coronary artery blockage leads to __ ___ or __.
    Myocardial ischemia or infarct
  6. What is the temporary lack of bloodflow to the heart?
    Myocardial ischemia
  7. What does cerebral artery blockage lead to?
    Stroke and permanent brain damage
  8. What does blockage of peripheral leg vessels lead to?
    Claudication (intermittent pain with exercise)
  9. What is the leading cause of death in US?
    Cardiovascular disease
  10. Coronary heart disease, stroke, hypertensive disease, congestice heart failure.... these are all what ?
    Types of Cardiovascular disease
  11. In the US 1.1 MILLION heart attacks that occur each year, __% is the survival rate.
  12. What is chest pain or pain in other areas resulting from occlusion of coronary arteries?
    Angina Pectoris
  13. Angina pectoris occurs when oxygen demand exceeds oxygen supply and usually subsides WHEN?
    When O2 demands subside
  14. How is Myocardial O2 demand estimated?
    • The double product or Rate Pressure Product
    • RPP = SBP x HR
  15. What is myocardial infarction?
    heart damage (death of ventricular muscle fibers)
  16. MI is due to?
    prolonged ischemia
  17. The degree of ventricular dysfunction depends on?
    the mass of ventricular permanently damaged
  18. These are prescription to reduce work of the heart.
    Beta blockers
  19. What is the metal mesh inserted into coronary artery or balloon catheters?
    intracoronary stents
  20. this keeps the coronary artery open
    intracoronary stents
  21. With stents __ therapy is needed to reduce risk of blood clots.
    anticoagulation therapy
  22. Druge-eluting stents are often used to prevent ___.
  23. -Diagnositc test for presence of CHD.
    -Radioactive substance
    -Used to detect myocardial perfusion
    -Ischemic myocardium does not take up thallium, so cold spots occur.
  24. -Radioisotope that binds to Red Blood Cells
    -Used for blood Pool imaging
    -Allows ESV(end systolic volume) and EDV (end diastolic volume) to be determined
    -Ejected fraction =(EDV-ESV) / EDV
    technetium 99m
  25. -Catheter is inserted in femoral artery
    -Catheter is pushed into coronary artery
    -Contrast dye injected
    -Dye of occlusion (narrowing) determined
    Coronary Angiography
  26. Former cardiac rehab?
    complete bed rest
  27. Cardiac rehabilitation consits of?
    • education and exercise
    • it helps clients with heart disease return to normal function within the limits of their disease
  28. What are the benifits of CHD with patients?
    • increase in VO2max
    • higher work rates achieved without angina
    • modest rehabilitaton is %BF, BP, TC and triglicerols, LDL
  29. what is the % reduction in mortality after a myocardial incarction with rehab?
  30. What lifestyle modifications in CHD patients can reverse CHD? (results 1st shown by Dean Ornish)
    • strict vegeterian diet
    • yoga
    • meditation
    • smoking cesation
    • physical activity
  31. Organization of Cardiac Rehab

    Phase 1
    Begin within 1-3 days of MI or revasularization procedure, the patient has already began the rehab.
  32. Organization of Cardiac Rehab

    Phase 2
    12 weeks of outpatient exercise program conducted in hospital
  33. Organization of Cardiac Rehab

    Phase 3
    Unmonitored outpatient exercise program
  34. Exercise prescription phase 2 and 3

    3-4 days a week
  35. Exercise prescription phase 2 and 3

    40-75% of VO2 max or HRR
  36. Exercise prescription phase 2 and 3

    20-40 min presession
  37. Exercise prescription phase 2 and 3

    Warm up and cool down:
    5-10 min
