Cardiogenic shock in pregnancy is a life‐threatening condition due to failure of the ventricles to produce an adequate cardiac output. Ischaemic heart disease, valvular heart disease, arrhythmia, cardiomyopathy and pulmonary and amniotic fluid embolism are the main causes of cardiogenic shock in pregnancy.

In trauma, patients can develop cardiogenic shock due to penetrating injury, cardiac tamponade, tension pneumothorax and myocardial contusion.

There is a significant overlap in the signs and symptoms between these forms of shock and hypovolaemic shock. One distinguishing feature is the extreme air hunger and orthopnoea seen in patients suffering cardiogenic shock. Listening to the chest may give clues of congestion due to increased pressure in the pulmonary circulation causing pulmonary oedema.

Cardiogenic shock has a high mortality and mandates multidisciplinary consultant management with involvement from cardiology, cardiac surgery and critical care. Transfer to a centre able to offer complex invasive cardiac support may be required.
