Show Answers:

  1. features of cardiac pain
    • visceral in nature (V for Vague!!)
    • hard to localize
    • hard to describe
  2. features of pericardial pain/pericarditis
    • easier to localize
    • NOT made worse by palpation
    • made worse by lying supine
    • made better by sitting up/leaning forward
  3. issue with unprovoked MFTPs
    can imitate chest wall pain
  4. non-modifiable cardiovascular risk factors
    • 1. age (men 45+, women 55+)
    • 2. gender (more in men)
    • 3. premature CHD
    • 4. family history (male relative <55, female relative <65)
  5. most people with a strong family history of heart disease also have other risk factors
  6. normal laminar flow through a normal artery leads to:
    HIGH arterial wall stress
  7. Problem: decreased arterial stress
    from risk factors causing endothelial activation
  8. endothelial activation
    increase in endothelial permeability
  9. problem: sustained endothelial activation
    sustained risks lead to decreased arterial stress causing the endothelium to favor vasoconstrictina nd platelet aggregation
  10. most suseptible place for dysfunction???

  12. significance and residual risk of: hypertension
    sig: the relationship is continuous and graded. no clear cut-off. can be partially reversed.

    residual: damage to the arterial endothemium. left ventrical hypertrophy.
  13. significance and residual risk of: tabacco smoking/environmental smoke
    sig: the risk is proportional to the # of cigs smoked and how deeply they're inhaled
  14. significance and residual risk of: diabetes mellitus
    sig: at risk even when blood glucose levels are under control

    residual: increased vascular permeability
  15. significance and residual risk of: left ventricular hypertrophy
    sig: effect of hypertension

    residual: change to ventricular myocardium

  29. CFR in normal arteries
    -> increase in demand-> increase blood flow-> no problems
  30. CFR with plaque < 50%
    -> increase demand-> significant reduction in flow-> typical angina and Levines sign
  31. CFR with plaque >90%
    -> no increase in demand-> no CFR to increase flow-> angina at rest
  32. most common type of angina??
  33. typical angina due to?
    coronary artery plaque fron decreased CFR
  34. featurs of typical angina
    • reproducable pattern (same level of exercise to reproduce)
    • attacks start abruptly and seize the patient
    • retrosternal pain (poorly localized, visceral in nature, strangling)
    • attacks last 1-5 minutes
    • pain relieve by rest!
  35. other triggers of typical angina?
    • emotion
    • exposure to cold
    • heavy metals
    • (these triggers decrease the amount of exertion needed to cause the angina)
  36. is typical angina pain graded?
    no, it is always the same, severity does not change
  37. levines sign
    the patient holds a clenched fist of the sternum when describing/experiencing the discomfort.
  38. pattern of typical angina
    • pain radiates to the left shoulder/arm (typically!)
    • location can vary greatly for each individual but a persons angina is always in the same place/predictable
  39. when to suspect typical angina?
    pain anywhere from umbilicus to eyebrows that is provoked by exercise and relieved by rest
  40. atypical angina due to problems with?
    coronary or intramyocardial arteries (they have very low flow reserve since surrounded by heart muscle)
  41. coronary artery near normal....smoking cigs:
    Prinzmetal angina/coronary vasospasm-> angina at rest
  42. normal intramyocardial arteries
    normal coronary As--> good blood flow--> no problems
  43. dysfunctinal intramyocardial arteries:
    increased resistance-> less exertion needed-> angina at rest
  44. common symptons of atypical angina
