Tissues damaged by myocardial infarction are replaced by fibrous connective tissue.

Question

Quizplus · Accepted Answer

Myocardial infarction, also known as a heart attack, occurs when the blood flow to a part of the heart is blocked, causing damage to the heart muscle. This damage is replaced by scar tissue made up of fibrous connective tissue. This scar tissue cannot contract or conduct electrical impulses like normal heart tissue, which can lead to complications such as arrhythmias and heart failure.
