Signs and tests

An examination will reveal:

  • Low blood pressure (less than 90 systolic)
  • Blood pressure drop of more than 10 points when you stand up after lying down (orthostatic hypotension)
  • Weak (thready) pulse

To diagnose cardiogenic shock, a catheter (tube) may be placed in the pulmonary artery (right heart catheterization). Measurements often indicate that blood is backing up into the lungs and the heart is not pumping properly.

Tests include:

  • Cardiac catheterization
  • Chest x-ray
  • Coronary angiography
  • Echocardiogram
  • Electrocardiogram
  • Nuclear scans

Other studies may be recommended to determine why the heart is not functioning properly.

Laboratory tests include:

  • Arterial blood gas
  • Blood chemistry ( chem-7 , chem-20 , electrolytes )
  • Cardiac enzymes (troponin, CKMB)
  • Complete blood count (CBC)
