History of Cardiogenic Shock
Definition 1
An event in the personal medical history of sustained, inadequate tissue perfusion secondary to cardiac dysfunction, generally defined as systolic blood pressure of less than 90 mm Hg of more than 1 hour and not responsive to fluid resuscitation alone. Associated signs of peripheral hypoperfusion (e.g. cool extremities, oliguria, altered sensorium) or a cardiac index of less than 2.2L/min/m^(2) are present. This clinical entity includes instances in which the systolic blood pressure is raised to 90 mmHg or more using inotropic agents, within the first hour. (from NIH Roadmap Cardiovascular Data Standards Working Group) (NCI Thesaurus)
Definition 2
An event with systolic BP < 90 mmHg for greater than 1 hour, not responsive to fluid resuscitation alone, and felt to be secondary to cardiac dysfunction. Associated signs of hypoperfusion (cool and clammy skin, oliguria, or altered sensorium) or a cardiac index of less than 2.2 L/min/m^(2) are present. This includes when the systolic BP increases to > 90 mmHg in response to inotropic agents in less than 1 hour. (NCI Thesaurus)
