Question

Which best explains why a patient who had a myocardial infarction will never fully recover, in spite of all the drugs prescribed to him? The drugs are only effective for extremely active, healthy individuals. The drugs cannot rebuild the cells that died, but they can limit the death of more. The drugs restore blood flow to some of the arteries, but not arteries in the legs. The drugs prevent another heart attack, but other damage has already occurred.

Answer 1

Answer:

A patient with a myocardial infarction cannot fully recover, despite the drugs he takes because the drugs prevent another heart attack, but other damage has already occurred.

Explanation:

Myocardial infarction is due to a blockage of the coronary arteries, with an absence of blood supply to areas of the heart muscle that end up dying.

A person with a myocardial infarction will not be able to recover the damaged areas of his heart —since the damage has occurred— but drugs are useful to decrease cardiac risk factors, improve coronary circulation and prevent a new attack.

The other options are not correct because:

• Myocardial infarction drugs are used in people with cardiovascular disease, not in very active healthy people.
• If a drug restores blood flow, it does so throughout the body.
• The drugs cannot rebuild the cells that died, but they can limit the death of more, does not explain why the patient with a heart attack does not fully recover.
