The heart is probably one of the most basic of human organs: a blood-filled hollow muscle, which together draw blood in the arteries can squeeze. Valves prevent the blood flows back when the muscle wall relaxes. The function of the heart is pumping blood around the body, mainly on the way in which oxygen and nutrients are carried on the back and waste. It made the heart muscle itself is so much work and a good blood supply to the heart itself of the greatest importance. The coronary arteries take care of this.

Remember that everyone experiences the same symptoms of heart attack with the same degree of intensity, so some older people and women may have less obvious symptoms. Some attacks occur suddenly, but most of them start slowly with mild pain and discomfort. Number of victims, uncertain whether or not a heart attack, think sometimes suffer from heartburn or indigestion. It may result in delays in medical care provided to patients.
Therefore, it is crucial to become familiar with the symptoms of heart attack, being able to recognize them and take them seriously. Here are the warning signs of heart attack :

The heart is one of the largest muscles of the body. The wall of the heart, called the myocardium, is actually the muscle that circulates the blood by making the pumping. During a heart attack, blockage of an artery Deprive the muscle of oxygenated blood. When the oxygen deficiency becomes severe enough to cause the death of many cells, it is a heart attack. In the medical context, a heart attack is designated acute myocardial infarction (MI).
Heart attack is directly responsible for approximately 11% of all deaths occurring in Canada every year. This figure represents 50% of all deaths attributable to coronary heart disease. Although heart attack is a very serious condition, the chances of survival increase dramatically if you can go to a hospital immediately.
The most typical symptom of a heart attack is an oppressive, crushing pain behind the breastbone. This pain often radiates to the jaw and left arm. The pain may also radiate to the back and shoulders. Also include nausea and sweating to the symptoms. Furthermore, sometimes heart palpitations, skipping the heart, dizziness, heart pounding and the observed tendency to fainting. Swoon is also possible, especially in the heavier strokes.
Sometimes the victims suffer from shortness of breath, vomiting and sweating. A pain in the chest that lasts more than 20 minutes or repeated short attacks of pain (more than 1 time per hour) are very suspicious for a heart attack. These alarms also need urgent medical attention. A person affected by a cardiac arrest is unconscious. The victim stopped breathing and unresponsive when he or she is drawn on the shoulders and gently agitated. The normal color disappears. You can check by breathing the head slightly backwards and push the chin up. You feel your cheek and listen to the mouth. With cardiac arrest stops the heart with pumping, so no blood and no oxygen circulating through the body. The result is that a person becomes unconscious within a few seconds and the risk of brain damage and death is significant.
Definition of heart attack
A heart attack is damage to one part of the heart, one or more blood vessels that supply blood to part of the heart are blocked, when this happens, blood does not circulate and the cells begin to die. Then the heart can not pump blood completely, resulting in cardiac arrest.
A victim of cardiac arrest whose heart still beats, has a better chance of saving that one found in cardiac arrest, if you provide first aid quickly.
While heart attacks occur suddenly seem to conditions that often cause can escalate silently for many years. Most heart attacks are the result of cardiovascular disease when fatty substances and other substances accumulate in the blood and begin to adhere to the walls of blood vessels.
