Medically known as myocardial infarction, in which a section of the heart dies because of lack of blood supply.
Damage (tissue death) of the heart muscle due to blockage of a coronary artery by either an embolus or thrombus.
Obstruction of the coronary arteries depriving the heart of blood and oxygen.
A condition in which the heart has a reduced blood supply because one of the arteries becomes blocked by a blood clot, causing myocardial ischaemia and myocardial infarction (informal).
Popular term for a disruption of the normal circulation of the heart.
A total or near-total blockage of one of the coronary arteries that supply the heart with oxygen; known medically as myocardial infarction. In most cases, the blockage is caused by a blood clot that forms at a point in the artery narrowed by fatty deposits. A spasm in an artery can also trigger a heart attack, although this is less common. Since the coronary arteries provide the heart muscle with its oxygen supply, tissue downstream from the blockage can die. The severity of the attack depends on the amount and location of affected heart tissue. Heart attack is one of the leading causes of sudden death and disability in the United States.
The damage and loss of function of an area of the heart muscle.
The condition that results when some of the tissue in the heart is prevented from receiving its normal blood supply and dies.
A cardiac emergency known as a heart attack transpires when a clot obstructs the blood flow in one or more of the heart’s arteries. This impedes the delivery of oxygen to the heart muscle, leading to the demise of cardiac tissue in the affected region.
There are several types of heart attack. Angina of effort. This type of heart attack is caused by a spasm of the artery to the heart, not by a blood clot. The sufferer usually knows that exercise brings on chest pain, has usually consulted a doctor about it, and carries with him either trinitrin tablets to chew or amyl nitrite capsules to break and sniff when the pain occurs. He will not be unconscious but will be sitting or standing clutching his chest and complaining of pain. If he has his tablets or capsules they should be administered; he should be kept quiet and still and the doctor sent for. Coronary thrombosis. This is due to a clot of blood in an artery suppplying the heart muscle. The victim is seized with a sudden, fierce, severe constricting pain around the center of the chest. This pain is often thought to be indigestion; it may radiate down either arm or up into the neck. It makes people terrified, and they are usually shocked and look ill. Imperative treatment is not to allow the casualty to move. He should be kept as still as possible, not allowed to help himself, and be laid down just where he is. A doctor should then be summoned. Stokes-Adams attacks. This is the rarest form of heart attack. It is caused by the heart beating so slowly (it may be only ten beats to the minute) that insufficient blood is reaching the brain and the person literally faints. First-aid treatment is similar to any ordinary faint; lay the patient down and send for the doctor.
