Diagnostic Evaluation

In clinical trials, cardiogenic shock has been defined as follows by the SHOCK investigators:[1]

1- Persistent hypotension:

AND

2- Severe decrease in the cardiac index (CI):

  • CI <1.8 L/min/m2 without support, or
  • CI <2.0 to 2.2 L/min/m2 with support

AND

3- Adequate or elevated filling pressure:

  • Left ventricular end-diastolic pressure >18 mm Hg, or
  • Right ventricular end-diastolic pressure >10 to 15 mm Hg
