In cardiogenic shock the systolic BP is lower than 90 mmHg and the urine production is low.

  • Acute myocardial infarction
    • When more than 40% of myocardium is affected
  • Obstructive hypertrophic cardiomyopathy
  • Pericardial tamponade
  • End-stage of heart failure
  • Arrhythmias

End-diastolic volume and end-diastolic pressure will increase as the heart can’t pump out blood. The central venous pressure will also increase.
