A heart attack occurs when blood flow loaded with oxygen no longer reaches the portion of the heart muscle. If blood flow is not restored immediately, that section will be affected muscle repair.
Signs and symptoms that precede a heart attack are not the same in all people. The first sign of heart attack can be a mild pain or minimal discomfort. In some people, symptoms do not appear. Heart attacks that do not have any specific event or intense are called silent myocardial stroke.
– Pain or discomfort in the chest. The most common symptom is pain precedes heart attack or chest discomfort. This event includes the occurrence of new or changes in pain intensity of pain already. Most heart attacks involve discomfort in the center or left side of the chest, which persists for several minutes or intermittently. The discomfort can feel like pressure, fullness or pain in the chest.
Persistent chest pain that occur even when you rest, may be signs of a heart attack. Any person suffering from such pain must be the doctor for inspection as soon as possible.
Angina. The symptoms of angina can be similar to those of a heart attack. Angina is chest pain that occurs in people with coronary artery disease. These pains often occur when persons are most active and persist only a few minutes and then disappear completely.
Shortness of breath. Often, people who have a heart attack shows this event. Most times may be the only sign that the person has a heart attack without other symptoms are present.
Anxiety. Individuals can have anxiety for no apparent reason, which can occur several hours before the onset of myocardial infarction.
Sweat. Suddenly, people who suffer a heart attack start to sweat and his skin felt clammy.

Although most people who experience a heart attack report chest pain during myocardial present, women may have different symptoms from those of men. These include:

- unusual fatigue lasting several days.
In a large study, involving 1,500 women who have had a myocardial infarction, the most commonly reported symptoms were unusual fatigue, sleep disturbance, difficulty breathing, indigestion and anxiety. Most women surveyed reported at least one of these symptoms more than one month before the heart attack.
