Answer

Coronary care units have reduced early mortality rates from acute MI by approximately 50% by providing immediate defibrillation and by facilitating the implementation of beneficial interventions. These interventions include the administration of intravenous (IV) medications and therapy designed to do the following:

  • Limit the extent of MI

  • Salvage jeopardized ischemic myocardium

  • Recanalize infarct-related arteries

See Treatment and Medication for more detail.
