Practice Question

 Which explanation by the nurse best describes why heart failure may develop after a myocardial infarction?

Answer Choices:

Correct Answer:

"After a heart attack, some heart muscle cells die and scar tissue forms, causing changes in heart structure and hormone levels that weaken the heart's pumping ability."

Rationale:

🟣Myocardial infarction (MI) causes irreversible necrosis of cardiac muscle tissue due to interrupted blood flow and oxygen supply.

🟣The affected area becomes fibrotic scar tissue, which cannot contract or conduct electrical impulses, reducing the overall cardiac output.

🟣This loss of functional myocardium triggers ventricular remodeling, where the remaining myocardium dilates and thickens in an attempt to compensate.

🟣Over time, these compensatory changes and neurohormonal activation (especially RAAS and sympathetic stimulation) lead to chronic heart failure.

🟣Heart failure post-MI thus develops primarily because the heart’s contractility and ejection fraction are diminished due to structural damage.
