  1. atherogenesis
    Developmental process of the atherosclerotic lesion.
  2. atheroma

  3. atherosclerosis
    Atherosclerosis begins as fatty streaks of the arterial wall in adolescence, progressing to hard fatty plaques that narrow and �harden� the arteries lumen in adulthood
  4. cardiogenic shock
    Shock that occurs when inadequate oxygen and nutrients are supplied to the tissues because of severe left ventricular failure
  5. coronary artery bypass grafting (CABG)

  13. pericarditis
    An inflammation of the pericardium
