What is the definition of cardiogenic shock?

Cardiogenic shock is defined as a state of inadequate tissue perfusion that occurs due to the heart's inability to pump effectively, which is essentially considered pump failure. In cardiogenic shock, the heart is unable to maintain sufficient cardiac output, leading to a reduction in blood flow to the organs and tissues. This can result from various conditions that impair the heart’s ability to contract, such as myocardial infarction or severe heart failure.

The condition is characterized by clinical manifestations such as hypotension, tachycardia, altered mental status, and signs of peripheral hypoperfusion. Recognizing the central role of the heart's pumping function in this type of shock is crucial for appropriate diagnosis and management. Understanding this context helps healthcare providers appreciate the critical nature of the heart's role and the need for swift intervention to support cardiac function and improve perfusion.
