What is the most likely reason that atherosclerotic plaque would be responsible for producing a myocardial infarction?
1. Atherosclerotic plaque builds up on the endocardium, preventing blood from leaving the atriums.
2. Atherosclerotic plaque results in a narrowing of 50% of the coronary arteries.
3. Atherosclerotic plaque impairs the ability of coronary arteries to constrict and dilate.
4. Atherosclerotic plaque causes a blockage that prevents blood from reaching the myocardium.

Rationale 1: Atherosclerotic plaque builds up in blood vessels, not in heart chambers.
Rationale 2: Atherosclerotic plaque can result in a myocardial infarction when blocked by 50%, but more likely it will not.
Rationale 3: Atherosclerotic plaque does damage the elasticity of blood vessels, but this is less likely to produce a myocardial infarction.
Rationale 4: Atherosclerotic plaque builds up inside of blood vessels that supply heart tissue oxygen-rich blood. When the blood flow is blocked, the myocardium is damaged.
Global Rationale: Atherosclerotic plaque builds up inside blood vessels that supply heart tissue oxygen-rich blood. When the blood flow is blocked, the myocardium is damaged.
