What Is Angina Pectoris?

Angina pectoris is the medical term for chest pain or discomfort usually due to coronary artery disease. It occurs when the heart muscle doesn’t get as much blood, and therefore as much oxygen, as it needs. This usually happens because one or more of the heart’s arteries has narrowed or blocked. During a typical angina attack, a person feels uncomfortable pressure, fullness, squeezing, or pain in the center of the chest. This discomfort may also be felt in the neck, jaw, shoulder, back, or arm.
