  27. abnormal thickening or hardening of vessel walls
  28. form of arteriosclerosis. thickening caused by hardening of soft deposits of intraarterial fat and fibrin that reduce lumen size. inflammatory disease
  29. begins with injury to endothelial cells of arteries
  30. Atherosclerosis development
    • Endotheial cell injury:
    • decreased antithrombolytics and vasodilators
    • growth factors stimulate smooth muscle proliferation
    • macrophages recruited to site and oxidize LDL with enzymes to produce foam cells
    •             foam cells form fatty streak continued               inflammation
    •                    Fibrous plaque overlays foam cells

    HTN develops if systemic vascular resistance elevates
  31. CAD
    diminishes bloodflow to myocardium

    persistent ischemia or complete occlusion= infarction or death of deprived mycardial cells/tissue


    Adipokines: hormones released from adipose cells

    Adiponectin: antiatherogenic hormone

    Decreased in obesity

    Anti-inflammatory effect, protects vascular endothelium

    Decrease of hormone increases CV risk
  32. Myocardial ischemia
    • atherosclerois is most common cause
    • Angina
    • Stable
    • Temporary ishcemia
    • exertion, vessels cant dilate in response to dmand
    • NTG and rest effective
    • Normal EKG, negative enzyme levels
  33. MI
    • unstable
    • advanced, reversible occurs at rest, NTG inffective

    normal transient, ST depression and T wave inversion, negative enzymes
  34. what happens in mi
    coronayr arteries cannot compensate for lack of o2: pronounced Q waves, ST elevation later, CPK-MB, LDH, SGOT, Troponins i and T indicate severity
  35. Subendocardial mi
    usually non-ST segment elevation (non-STEMI)

    ST depression, T wave inversion w/o Q waves
  36. Transmural MI
    marked elevation in ST segments on EKG (STEMI)
