Angina pectoris (or simply angina) is recurring chest pain or discomfort that happens when some part of the heart does not receive enough blood.
Angina is a symptom of coronary heart disease (CHD), which occurs when arteries that carry blood to the heart become narrowed and blocked due to atherosclerosis.
Angina vs. heart attack
Angina may have similar symptoms as a heart attack, such as a crushing, squeezing pain in the chest; a feeling of pressure in the chest; or pain radiating in the arms, shoulders, jaw, neck, and/or back.
However, unlike the chest pain associated with a heart attack, the pain from angina usually goes away within a few minutes with rest or with the use of a cardiac prescription medication (i.e., nitroglycerin).
