Detailed explanation-1: -Myocardial infarction (MI) refers to tissue death (infarction) of the heart muscle (myocardium) caused by ischaemia, the lack of oxygen delivery to myocardial tissue. It is a type of acute coronary syndrome, which describes a sudden or short-term change in symptoms related to blood flow to the heart.

Detailed explanation-2: -When this happens, part of the heart “dies.” The medical term for the area of dead muscle is called the “infarct.” The remaining, healthy tissue must take over the job of pumping blood, an extra burden that may weaken the heart’s pumping ability.

Detailed explanation-3: -If too much muscle dies, the heart is not able to pump enough blood to the rest of the body. Damage to the heart cells that regulate the heartbeat may cause fatal heart rhythm problems. Sometimes, the heart muscle weakens and can tear as a result of the damage. This causes a fatal hemorrhage (bleeding).

Detailed explanation-4: -A heart attack (myocardial infarction) 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 blocked.
