'''Angina''' is chest pain or discomfort you get when your [[heart]] muscle does not get enough [[blood]]. It may feel like pressure or a squeezing pain in your chest. It may feel like indigestion. You may also feel pain in your shoulders, arms, neck, jaw or back.
Angina is a symptom of [[coronary artery disease]] (CAD), the most common [[heart disease]]. CAD happens when a sticky substance called [[plaque]] builds up in the arteries that supply blood to the heart, reducing blood flow.
There are three types of angina: stable, unstable and variant. Unstable angina is the most dangerous. It does not follow a pattern and can happen without physical exertion. It is does not go away with rest or medicine. It is a sign that you could have a [[heart attack]] soon.
