What is a heart attack?

Myocardial infarction. Definition

Acute myocardial infarction is popularly called him and his cause is myocardial necrosis or cell death by lack of blood supply caused by an obstruction or stenosis of the artery


How a heart attack occurs?

Acute myocardial infarction occurs when these four factors described below occur:

  • - The coronary arteries narrow
  • - The myocardium does not get oxygen
  • - The myocardium is unable to produce energy to move why not get oxygen
  • - The tissues negrosa because their cells do not receive blood

Why a heart attack occurs?

A myocardial infarction occurs when the coronary arteries are narrowed for various reasons. Among the most common causes are the blood clot and atherosclerosis consisting of the formation of fatty deposits in artery walls. These deposits are formed because of the factors noted below.

Risk factors for stroke

The factors listed below can clog the coronary arteries causing acute myocardial infarction: hypertension, high cholesterol, snuff, obesity, sedentary lifestyle, age.

Warning symptoms of stroke

Symptoms that will list below and are common as to cause myocardial infarction, not all of them have to be submitted. The most common is that when a situation of myocardial infarction occurs a variable combination of some of these factors will be discussed below.

  • - Pain in the area of ​​the sternum does not vary with movement or breathing. It's a pretty intense pain that may radiate to other parts of the body like the back, left arm or neck. It is unusual but can also radiate pain to his right arm.
  • - Cold sweat and dizziness associated with any of the above symptoms.
  • - Like vomiting, unconsciousness, abdominal pain or trouble breathing.

Consequences after suffering a heart attack

Acute myocardial infarction can be very extensive or simply cover a small area.
If acute myocardial infarction has been very extensive, heart failure you may be suffering for life, even sometimes with pulmonary congestion.
If acute myocardial infarction has covered a small area of ​​the body it will be possible to develop a normal life but it should prevent care of controlling the risk factors that can cause a heart attack.

The defibrillator or pacemaker are instruments that treat some people after suffering an acute myocardial infarction with ventricular arrhythmias or heart blockages.
If the patient has an unstable angina should be treated especially because at high risk of acute myocardial infarction sudden death. The way both angina and heart attacks are triggered are virtually identical, but in one case the first one fails to give complete occlusion of the coronary artery by thrombus and a cardiac cell death occurs. Known as angina start not to make the patient has any pain or tightness in the middle of the chest may reach extended to the arms, jaw, back and neck. Although in principle it is not as dangerous angina and acute myocardial infarction, also it must be treated as an emergency by the high risk that relates to this with the possibility of suffering myocardial infarction, sudden death or serious arrhythmia.
