Heart attack is the cessation of blood flow, even if only for a moment, that led to the heart, and causes some heart cells to die. Heart disease is the number one cause of death in adults in the United States. Each year, in the United States:
* 1.5 million people suffered heart attacks.
* 478,000 people die from coronary heart disease.
* 407,000 people experience the transition operation.
* 300,000 people undergo angioplasty.
Heart disease, stroke and peripheral arterial disease is a deadly disease. Worldwide, the number of people with this disease continues to grow. The three categories of disease is not out of an unhealthy lifestyle that a lot done in line with the changing pattern of life.
These factors trigger a heart attack is smoking, eating foods high berkolestrol, lack of movement, supine exercise, stress, and less rest.

Know Your Heart
The heart is a muscular organ, cone-shaped, hollow and with its base above and below the peak. Its apex (peak) tilted to the left. Heart weight of approximately 300 grams. For cardiac function as an efficient pumping, heart muscles, cavity top and bottom cavity must alternately contract. The rate of heartbeat or pulse-pumping work is controlled naturally by a "regulatory rhythm". It consists of a group in particular, called nodes sinotrialis, which is located inside the wall of the right atrium. An electrical impulse is transmitted from the node to a second porch sinotrialis make both of them to contract simultaneously.
Electric current is then forwarded on to the walls of the chamber, which in turn makes the chambers contract simultaneously. Period of contraction is called systole. Furthermore, this period followed by a short relaxation period - roughly 0.4 seconds - which is called diastole, before the next impulse came. Sinotrialus node produces between 60 to 72 impulses like this every minute when the heart is relaxed. Production of these impulses is also controlled by a part of the nervous system called the autonomic nervous system, which worked out what we want. Built-in electric systems is what produces the heart muscle contractions beirama called heartbeat.

Symptoms of Heart Attack
These symptoms are usually different for each person. A heart attack may begin with pain that is unclear, vague discomfort, or chest tightness in the middle. Sometimes, a heart attack caused only mild discomfort at all so it is often mistaken for indigestion, or even escape the attention at all. In this case, the only way that allows the detection of a heart attack is when should undergo ECG examination for other reasons that may not be related.
On the other hand, a heart attack may bring the worst pain ever experienced - extraordinary tightness or feeling pinched in the chest, throat or stomach. Can also heat or cold sweat, foot pain once and a sense of fear that the end is approaching. Also may feel more comfortable when sitting than when lying down and breathing is so crowded that may not be relaxed. Nausea and dizziness and even vomiting, and even more of that when it comes to collapse and faint.

There are some more specific symptoms, including:
* Pain. If the muscle does not get enough blood (a condition called ischemia), then the oxygen is inadequate and the result of excessive metabolic causes cramps or spasms. Angina is a feeling of tightness in the chest or a feeling of chest crumpled, which arises when the heart muscle not getting enough blood. The type and severity of pain or discomfort will vary in each person. Some people who experience lack of blood flow could not feel any pain at all (a condition called silent ischemia).
* Shortness of breath is a symptom commonly found in heart failure. Shortness is the result of the influx of fluid into the air cavities in the lungs (pulmonary congestion or pulmonary edema).
* Fatigue or tiredness. If the heart is not pumping effectively, the flow of blood to muscles during activity will decrease, causing the patient to feel weak and tired. These symptoms are often mild. To overcome this, patients typically reduce their activity gradually or think this phenomenon as part of aging.
* Palpitations (heart palpitations)
* Dizziness and fainting. Decrease in blood flow due to rate or heart rhythm is abnormal, or because of poor pumping ability, can cause dizziness and fainting.
