  5. angioplasty
    A procedure in which a small balloon is used to open a partially blocked coronary artery by flattening the plaque deposit and stretching the lumen.
  6. anticoagulant
    Medication administered to slow blood clotting and to prevent new clots from forming; also known as a thrombolytic agent.
  7. aplastic anemia
    A type of anemia that is marked by an absence of all formed blood elements.

  10. atheroma
    A deposit of plaque on or within the arterial wall.
  11. atherosclerosis
    Hardening and narrowing of the arteries due to a buildup of cholesterol plaque.
  12. atrial fibrillation
    occurs when the normal rhythmic contractions of the atria are replaced by rapid irregular twitching of the muscular heart wall
  13. automated external defibrillator
    device that samples the heart's electrical rhythms, and when necessary, externally shocks the heart to restore a normal cardiac rhythm
  14. beta-blocker
    A medication that reduces the workload of the heart by slowing the rate of the heart beat

    Any pathologic condition of the cellular elements of the blood.
  16. bradycardia
    An abnormally slow heartbeat.
  17. cardiac arrest
    An event in which the heart abruptly stops or develops a very abnormal arrhythmia that prevents it from pumping blood
  18. cardiac catheterization
    A procedure in which a catheter is passed into a vein or artery and is guided into the heart.
  19. cardiomyopathy
    The term used to describe all diseases of the heart muscle.
  20. carotid endarterectomy
    Surgical removal of the lining of a portion of a clogged carotid artery leading to the brain
  21. cholesterol
    A fatty substance that travels through the blood and is found in all parts of the body.
  22. chronic venous insufficiency
    A condition in which venous circulation is inadequate due to partial vein blockage or leakage of venous valves.
  23. coronary thrombosis
    Damage to the heart muscle caused by a thrombus blocking a coronary artery.
  24. defibrillation
    The use of electrical shock to restore the heart's normal rhythm.
  25. diuretic
    Medication administered to stimulate the kidneys to increase the secretion of urine to rid the body of excess sodium and water.
  26. electrocardiogram
    A record of the electrical activity of the myocardium.
  27. embolism
    Blockage of a vessel by an embolus.
  28. embolus
    A foreign object such as a blood clot, a quantity of air or gas, or a bit of tissue or tumor that is circulating in the blood.

  31. hemoglobin
    The iron-containing pigment of the erythrocytes that transports oxygen from the lungs to all of the body tissues.
  32. hemolytic anemia
    A condition of an inadequate number of circulating erythrocytes due to the premature destruction of these cells by the spleen.
  33. hemostasis
    To control bleeding.
  34. ischemic heart disease
    A group of cardiac disabilities resulting from an insufficient supply of oxygenated blood to the heart.

    A malignancy characterized by a progressive increase of abnormal leukocytes.
  36. leukocytes
    White blood cells.
  37. leukopenia
    Any situation in which the total number of leukocytes in the circulating blood is less than normal.
  38. megaloblastic anemia
    The bone marrow produces abnormal red blood cells known as megaloblasts, which have a reduced capacity to carry oxygen.
  39. myelodysplastic syndrome
    A group of bone marrow disorders that are characterized by the insufficient production of one or more types of blood cells due to dysfunction of the bone marrow.
