After a myocardial infarction, which complication is commonly monitored?

• A. Hypoglycemia
• B. Heart failure
• C. Liver failure
• D. Renal cancer

Answer: (B)

After a myocardial infarction, the heart’s pumping ability is often reduced because the damaged muscle cannot contract effectively. This makes heart failure a common and important complication to monitor, as fluid can back up and the patient may develop shortness of breath, pulmonary congestion, edema, and signs of low cardiac output. Early detection allows timely management with therapies that support circulation and reduce fluid overload.

Hypoglycemia, while important in other contexts, is not a typical direct post-MI complication. Liver failure and renal cancer are not common or immediate issues to monitor after a heart attack.
