There are many symptoms which are associated with a heart attack.  Importantly, however, it is critical to recognize that 33% of the Americans who arrive at an Emergency Room with a heart attack, have NO chest pain.  The most common symptoms are listed below:

Ischemia:  This is a general term that indicates “insufficient blood flow.”  If an artery is severely narrowed, or blocked, ischemia is the result.  Ischemia can be the result of an infarction, or it may be a transient event brought on by physical stress (in the case of a stenosis).   An ischemic condition may, or may not, result in chest pain (angina).

Chest Pain:  The most obvious symptom, this pain can be manifest as anything from a “crushing” pain, to a “mild discomfort.”  In some cases, it can even be best described as “heartburn.”  This pain in the chest, when it is transient, is called angina. (an' gin uh)

Shortness of Breath:  Easily overlooked, since it often occurs while under exertion, this can be indicative of ischemia or heart attack.

Numbness or Tingling in Arm:  This is a symptom which is also sometimes associated with a heart attack.

Jaw Pain:  Like the arm numbness, this is occasionally reported by victims of heart attack.
