Myocardial infarction (MI) means that part of the heart muscle suddenly loses its blood supply. Without having immediate treatment, this can lead to harm to the affected part of the heart. An MI is usually called a heart attack or a coronary thrombosis.
The heart pumps blood into arteries (blood vessels) which take the blood to each and every part of the body. The heart muscle, like all muscles, always requirements an excellent blood supply. The coronary arteries take blood to the heart muscle. The principal coronary arteries branch off from the aorta. (The aorta. is the significant artery that takes oxygen-rich blood from the heart chambers to the body.) The major coronary arteries divide into smaller branches then take blood to all parts of the heart muscle.
If a person has an MI, a coronary artery, or one of its smaller branches is suddenly blocked. The portion of the heart muscle supplied by this artery loses its oxygen and blood supply. This portion of the heart muscle is at risk of dying, unless the blockage is promptly undone. The word 'infarction' means death of some tissue due to a blocked artery which stops blood from obtaining past.
If among the most important coronary arteries is blocked, a large part of the heart muscle is affected. If a smaller branch artery is blocked, a smaller amount of heart muscle is affected. In people today who survive an MI, the part of the heart muscle that dies ('infarcts') is replaced by scar tissue over the next few weeks.
A smaller MI occasionally happens without causing discomfort (a 'silent MI'). It might be pain-free, or often the discomfort is mild and you might feel it really is only heartburn or 'wind'. Collapse and sudden death might occur with a big or severe MI.
MI's are simpler to diagnose nowadays as a result of the boost in technologies advances. They may turn out to be avoidable through higher education and healthier selections in lifestyle
