Which pharmacologic strategy is commonly used to support a patient in cardiogenic shock?

• A. Dopamine
• B. Norepinephrine plus dobutamine
• C. Vasopressin infusion only
• D. Positive inotropic support alone

Answer: (D)

In cardiogenic shock the goal is to restore perfusion by both boosting the heart’s output and maintaining adequate blood pressure. The most effective approach is a combination: a vasopressor to raise systemic vascular resistance and mean arterial pressure, and an inotrope to improve heart contractility and stroke volume. A common choice is norepinephrine to support pressure, with adding dobutamine if cardiac output remains low. This dual strategy addresses the low output and the hypotension that drive tissue hypoperfusion. Relying on inotropic support alone can improve contractility but won’t reliably raise blood pressure, leaving organs underperfused. Single-agent vasopressors or other options without addressing both components are less effective in this scenario.
