PATHOLOGY

Detailed explanation-1: -A heart attack happens when one or more areas of the heart muscle don’t get enough oxygen. This happens when blood flow to the heart muscle is narrowed or blocked. This causes areas of the heart muscle to become damaged or die (infarct). A blood clot is the usual cause of a heart attack.

Detailed explanation-2: -A heart attack, also called a myocardial infarction, happens when a part of the heart muscle doesn’t get enough blood. The more time that passes without treatment to restore blood flow, the greater the damage to the heart muscle. Coronary artery disease (CAD) is the main cause of heart attack.

Detailed explanation-3: -People often use these terms interchangeably, but they’re not the same. A heart attack is when blood flow to the heart is blocked. Sudden cardiac arrest is when the heart malfunctions and suddenly stops beating. A heart attack is a “circulation” problem and sudden cardiac arrest is an “electrical” problem.
