The word heart attack (originating in Latin infartus) is part of the medical vocabulary and refers to the necrosis of a certain organ (or on behalf of him) caused by the blood supply interruption generated following a blockage in any artery . The term also names the increase in proportions of the affected organ.
The obstruction of arteries leading to a case of heart attack can occur due to the vessel's own elements (such as atheroma plaques ) or by external elements (a tumor that compresses the artery, a hernia , a wound ).
Although a heart attack can take place in all the organs of the human body, the term is usually used in general terms to describe the acute myocardial infarction (also know as heart attack or heart attack ). This infarction (classified as acute for its sudden condition) is characterized by an insufficient flow of blood arrival in part of the heart due to an obstruction in any of the coronary arteries.
The obstruction, experts say, produces a ischemia (a cellular damage due to the decrease in blood flow and the consequent decrease in the capacity of oxygenation ) that, if not treated in time, results in the death of cardiac tissue and subsequent necrosis.
Men over 40 years and women over 50 years of age are the population groups that are most affected by this type of infarction that has chest pain as its main symptoms, which can spread to the arms and at neck, and a respiratory difficulty of some forcefulness.
However, although these make up the most common clinical picture there are also others such as loss of consciousness, weakness or drowsiness. These last three symptoms are more frequent in the case of women than in men.
And all this without forgetting that it is estimated that approximately one quarter of heart attacks the affected person does not experience any of these symptoms. In this case, those who suffer from it are mostly the elderly and patients suffering from diabetes.
In addition to all of the above, it is important to highlight the fact that those who suffer a myocardial infarction, and once they are in the corresponding hospital, it is common for them to undergo what is known as catheterization. This is a diagnostic and therapeutic type test, at the same time, which seeks not only to verify the damage caused by said ailment but also to carry out, for example, the placement of stents to avoid a new collapse.
With local anesthesia, this intervention is carried out, which involves the insertion of a catheter through the vascular system.
The diseases of coronary arteries, atherosclerosis, heart rhythm disorders and some modifiable habits (such as obesity , he smoking , excessive consumption of alcohol or the high level of stress ) increase the risk of having a heart attack.
He heart attack , meanwhile, is the stroke (ACV ) ischemic or brain Atack . It occurs when blood flow is interrupted by brain , affecting different functions and causing the death of part of the brain mass.
