text: A<unk>  <unk>  is an area of a hospital specialized in the care of patients who are critically ill with heart disease.  The<unk>  is a subset or subtype of intensive care unit (ICU) care. The role of the<unk>  <unk>  varies tremendously between hospital centers. In small rural centers, any patient who is being “ruled out” for a myocardial infarction (MI) may be placed in a<unk> .  In contrast, in large urban teaching hospitals, only those patients requiring invasive hemodynamic monitoring with a pulmonary artery catheter, mechanical ventilation, and intraaortic balloon pump (IABP) counterpulsation may be placed in the<unk> .  Many hospitals contain both a<unk>  for critically ill patients and units called either an "intermediate care unit", "progressive care unit", "telemetry floor" or "step down unit" for patients who are not as crtically ill. These units provide a level of care that is intermediate to that of the intensive care unit and that of the general medical floor. These units typically serve patients who require cardiac telemetry such as those with unstable angina. In those hopsitals who provide cardiothoracic surgery services, there is often a<unk>  dedicated to the management of patients following<unk>  artery bypss grafting (CABG), aortic valve surgery or other thoracic surgery.
