What is the treatment for hypotension in a left-sided myocardial infarction?

• A. Use inotropes and pressors, and avoid fluids
• B. Give fluids aggressively
• C. Use nitrates only
• D. Maintain bed rest without intervention

Answer: (A)

When hypotension occurs with a left‑sided myocardial infarction, the priority is to restore perfusion by supporting the heart’s pumping ability and increasing vascular tone. Inotropes help the heart contract more effectively, while vasopressors raise systemic vascular resistance to push blood back to vital organs and improve coronary perfusion. Fluids are not the default here because the primary issue is pump failure, not volume depletion; adding fluids can push blood into the failing left ventricle and worsen pulmonary edema and pulmonary congestion. Nitrates, which lower preload and afterload, can further drop blood pressure and reduce coronary perfusion in a hypotensive patient, so they’re avoided until stability is achieved. Bed rest or delaying active intervention doesn’t address the underlying hemodynamic instability. In practice, this approach translates to using inotropes and pressors to stabilize the patient while avoiding unnecessary fluids and vasodilators.
