is a signal that your heart is not receiving sufficient oxygen
heart is supplied with oxygen through blood. blood is distributed to the entire heart muscle by 4 arteries (pipes :) ), called coronary arteries.
if one of this artery
gets narrowed or thicked, than the heart muscle (myocardium) is starved from oxygen and suffers a loss of function.
Untreated, the process may lead to heart attack
The main cause which may lead to such unwanted events, accompanied by chest pain are:
* CHD (Coronary Heart Disease
* Blood Pressure
If you want more answes, I use to write more on chest pain and heart attacks on my site at www.allheartattack.com
If the chest pains are persistent, I suggest you to contact your doctor immediately and ask for a heart investigation. It may start with a ECG (ElectroCardioGram) and USG (echo) - both unpainfull. So, don't delay because this might be serious.
hope this helped you,
