Physiologic profiles in circulatory support.

Measurements of hemodynamic, oxygen transport, and tissue utilization functions were incorporated into a physiologic profile assessment system in order to evaluate patients who are candidates for mechanical support of the failing heart. Circulatory function was assessed in patients with acute myocardial infarction associated with diminished peripheral perfusion and compared to an age-matched, normal patient group. Serial studies performed prior to and during intra-aortic balloon counterpulsation provide a means to assess circulatory status accurately and document the efficacy of therapeutic interventions.
