A heart
attack is a sudden serious medical condition in which someone’s
heart stops working, causing them great pain. It is the most common
of the heart diseases and occurs when blood flow to the heart and
part of it is blocked, often by a blood clot, which is a thick almost
solid mass formed when blood dries.This situation is usually caused
by arteriosclerosis a disease in which arteries become hard, stopping
the blood from flowing through them smoothly. Sometimes, the clot
is called coronary thrombosis or coronary occlusion, since is often
caused by rupturing or tearing of plaque in an artery.
Muscle cells damaged and die, if blood supply is cut off for a long
time, leading to disability or death depending on the extent of
the damage to the muscle. A heart attack it is also known as myocardial
infarction, which can also occur when a coronary artery temporarily
contracts or goes into spasm, decreasing or cutting the blood flowing
to the heart. A heart attack represents on or about half of all
coronary heart disease deaths and can be caused by nearly all types
of heart illness. There exist three main symptoms to know when a
heart attack occurs. One is the pressure or pain in the centre of
the chest, lasting more than a few minutes or going away and coming
back. A second symptom is when pain spreads to the shoulders, neck
or arms. A third symptom consists in a chest discomfort combined
with light-headedness, fainting, sweating, nausea or shortness of
breath.
