Question

Mr. Smith had a myocardial infarction (MI) about 5 weeks ago. While he survived, he did not get to the hospital early enough to prevent tissue damage and scar tissue has begun forming. What zone of tissue damage is this?

A. Ischemic zone
B. Area of hypoxia
C. Area of injury
D. Area of necrosis

Answer 1

The zone of tissue damage where scar tissue has begun to form 5 weeks after Mr. Smith's myocardial infarction (MI) is the area of necrosis.

Step-by-step explanation:

Mr. Smith had a myocardial infarction (MI), commonly known as a heart attack, which typically causes damage to heart muscle from the death of myocardial cells due to a blockage in blood flow to part of the heart. Given that scar tissue has begun forming approximately 5 weeks post-MI, the zone of tissue damage Mr. Smith is experiencing is known as the area of necrosis. This necrotic area is where the myocardial cells have died and been replaced by scar tissue, a process that is a part of the body's natural healing mechanism following the MI.
