Question

Quizplus · Accepted Answer

Myocardial infarction, also known as a heart attack, occurs when there is a blockage of blood vessels that prevent adequate blood flow to the heart. This can lead to damage or death of the heart muscle. Arteries hardening or losing elasticity (A) and elevated heart rate (B) can increase the risk of a heart attack, but they are not the direct cause. The heart stopping (C) is a result of a heart attack, not the cause.
