When the heart muscle does not get enough blood flow, which carries oxygen to the heart muscle, it results in chest pain (angina pectoris or just angina). Chest pain can occur for several reasons, but it should always be taken seriously as it could be the first sign of a heart attack.
Chest pain as a symptom of a heart attack can be different for everyone and has even been found to be different in women than in men. The most classic chest pain is a sharp pain in the left chest with radiation to the left arm. More subtle signs of chest pain can be: pressure or tightness in the chest, difficulty breathing or shortness of breath, nausea or heart burn-like pain, pain in the jaw or throat, light headedness or weakness, and anxiety.
Chest pain should never be ignored, if you experience any of these symptoms you should consult your physician or go to an emergency room.
