The most common symptom is chest pain. Angina can also cause shortness of breath, sweating, and nausea. If you have any of these symptoms, call your doctor or emergency services right away.
Angina is caused by a lack of blood flow to the heart muscle. This can be due to a blockage in one of the coronary arteries (the blood vessels that supply blood to the heart muscle), or it can be due to spasm of the coronary arteries. When the heart doesn't get enough oxygen-rich blood, it hurts. This pain is called angina pectoris.
