cardio pathology terms
Show Answers:

  1. the resistance that the ventricle of the heart has to overcome to eject the blood from the ventricle chamber during systole.
  2. hemorrhage that happens immediately prior to death, as a result of tissue anoxia.
    agonal hemorrhage
  3. a sac formed by thte dilation of the wall of an artery, vein or the heart; it is filled with fluid or clotted blood, often forming a pulsing tumor.
  4. any of a group of diseases characterized by thickening and loss of elasticity of arterial walls.
  5. inflammation of an artery.
  6. a common form of arteriosclerosis with formation of deposits of yellowish plaques (atheromas) containing cholesterol, lipoid material, and lipophages in the intima and inner media of large and medium-sized arteries.
  7. slowness of a heart beat, as evidenced by slowing of pulse rate.
  8. acute compression of the heart caused by increased intrapericardial pressure due to the collection of blood or fluid in the pericardium from rupture of the heart, penetrating trauma, or progressive effusion (abnormal accumulation of fluid in the pericardial cavity).
    cardiac tamponade
  9. threadlike bands of fibrous tissue which attach on one end to the edges of the tricuspid and mitral valves of the heart and on the other end to the papillary muscles.
    chordae tendineae
  10. excessive or abnormal accumulation of fluid, as of blood in part.
  11. acute overload of the right ventricle due to pulmonary hypertension, usually resulting from acute pulmonary embolism.
    cor pulmonale, acute
  12. heart disease characterized by hypertrophy and sometimes dilation of the right ventricle secondary to disease affecting the structure or function of the lungs, but excluding those pulmonary disorders resulting from congenital heart disease or from diseases primarily affecting the left side of the heart.
    cor pulmonale, chronic
  13. a condition in which blood clots form throughout the body's small blood vessels.
    disseminated intravascular coagulation (DIC)
  14. congenital displacement of the heart outside the thoracic cavity because of maldevelopment of the pericardium and sternum.
    ectopia cordis
  15. inflammation of the tunica intima of an artery, intmitis.
  16. diffuse patchy thickening of the mural endocardium, particularly in the left ventricle due to proliferation of collagenous and elastic tissue. Usually in association with congenital cardiac malformations.
    endocardial fibroelastosis
  17. irregular uncoordinated contraction of cardiac myocytes, either individually or in small groups.
  18. the intrinsic (belonging naturally, essential) ability of cardiac muscles to produce greater active force in response to stretch, a phenomenon known as lenth-dependant activation.
    frank-starling phenomenon
  19. Atoms or groups of atoms with and odd (unpaired) number of electrons and can be formed when oxygen interacts with certain molecules. They react with important cellular components and cause cellular damage.
  20. localized areas of subendocardial fribrosis, usually in the atria, thought to be due to jets of blood caused by valvular lesions.
    jet lesion
  21. calcification seen in areas of necrotic tissue.
    dystrophic mineralization
  22. calcification that occurs usually when there is hypercalcemia in normal tissue. (usually a parathyroid problem)
    metastatic mineralization
  23. a thick bundle of muscle in the central part of the right ventricle of the heart.
    moderator band
  24. a small muscle within the heart that anchors the heart valves.
    papillary muscle
  25. inflammation of a vein.
  26. a serious blood vessel disease in which small and medium-sized arteries become swollen and damaged.
    polyarteritis nodosa
  27. initial stretching of the cardiac myocytes prior to contraction.
  28. refers to the pathological state of cardiac muscles in which it has to contract while experiencing and excessive afterload.
    pressure overload
  29. (noncancerous cardiac tumor) a benign tumor of striated muscle.
    rhabdomyoma (-tosis)
  30. a blood clot that breaks off from a larger blood clot in the heart, travels down the aorta and lodges at the saddle.
    saddle thrombus
  31. occurs when the heart is unable to pump as much blood as the body needs.
  32. the sudden and temporary loss of consciousness that is also described as fainting or passing out.
  33. a faster than normal heart beat (heart rate) at rest.
  34. swelling (inflammation) of a vein caused by a blood clot.
  35. irregular bundles and bands of muscle projecting from a great part of the interior walls of the ventricles of the heart.
    trabecular muscles
  36. inflammation of blood vessels.
  37. refers to the state of one of the chambers of the heart in which too large a volume of blood exists within it for it to function efficiently.
    volume overload
  38. 1. the innermost layer of an artery or vein.
    2. the middle layer of an artery or vein.
    3. the strong outer covering(layer) of an artery or vein.
    • 1. tunica intima
    • 2. tunica media
    • 3. tunica adventitia
  39. restriction of blood supply to tissues.
