Which of the following hemodynamic changes is associated with cardiogenic shock?

Cardiogenic shock is characterized by the heart's inability to pump blood effectively, resulting in decreased cardiac output and inadequate tissue perfusion. In this state, one of the compensatory mechanisms that the body employs is to increase systemic vascular resistance. This occurs as the body tries to maintain blood pressure and ensure that vital organs receive an adequate blood supply, despite the compromised function of the heart.

When cardiac output is low, the body releases catecholamines, which lead to vasoconstriction. This vasoconstriction raises systemic vascular resistance, which can help to preserve mean arterial pressure and redirect blood flow to critical organs like the brain and heart. Hence, the increase in systemic vascular resistance is a hallmark of the compensatory response to cardiogenic shock.

The other options do not align with the typical physiological responses observed in cardiogenic shock. Stroke volume typically decreases due to the impaired function of the heart. Central venous pressure often increases because of fluid backing up into the venous system as heart function wanes. Cardiac output is, by definition, significantly decreased in cardiogenic shock due to the heart's diminished ability to pump effectively. Understanding these changes is crucial for diagnosing and managing the condition effectively.
