What is a cause of cardiogenic shock other than myocardial infarction?
Show Hint
Each mechanical and right-sided cause can produce shock.
Updated On: Jun 24, 2026
- Acute mitral regurgitation
- Ventricular septal rupture
- Isolated right ventricular shock
- All of the above
Show Solution
The Correct Option is D
Solution and Explanation
Step 1: Beyond pump failure from infarction, cardiogenic shock can stem from mechanical and right-heart problems, so we evaluate each option.
Step 2: Sudden severe mitral regurgitation collapses forward cardiac output, a classic cause of acute cardiogenic shock.
Step 3: A ruptured ventricular septum creates a large left-to-right shunt that starves the systemic circulation, and isolated right ventricular failure cannot fill the left ventricle, both leading to shock.
Step 4: Since every listed entity independently produces cardiogenic shock, together with tamponade and cardiac rupture, the inclusive option is correct.
\[\boxed{\text{All of the above}}\]
