Heart attack is also known as myocardial infarction (MI) as per medical terminology. It causes permanent harm to the heart muscle. The muscles of the heart need a supply of blood which is rich in oxygen. The coronary artery aids the heart in this process with blood supply. During a heart attack, the blood ceases to flow because the arteries tend to narrow down. The outer shell cracks and blood starts to clot, this in turn blocks the artery and the muscle starts ‘starving’ for oxygen. The heart muscle suddenly dies and causes irreversible damage resulting to a heart attack.
Heart attack can occur without a coronary artery disease or even at rest. The heart muscles start healing 8 weeks after the heart attack. However, the blood pumping ability of the heart is reduced to a great extent after a heart attack. It is important to get proper treatment as soon as you get a heart attack or it might damage you heart tissues greatly and the chances of survival can be reduced.
How can heart attack be diagnosed?
It is vital to get immediate medical help if you develop a heart attack. Certain drugs are used to prevent and break up blood clots inside the heart. These medications should be given as soon as possible to reduce the amount of damage to the heart.
