• Your heart is a muscle. It pumps oxygen-rich blood to your whole body. Your heart also needs oxygen to work. Blood vessels called coronary arteries carry blood with oxygen to your heart.

• In healthy coronary arteries, blood flows freely to bring oxygen to the heart. In coronary heart disease, these arteries become stiff and narrow. This lowers blood flow and the amount of oxygen that gets to the heart

• With exercise or emotional stress, the heart works harder

This can lead to chest pain known as unstable angina. It often occurs at rest. Unstable angina is a medical emergency and requires medical help right away1,2

If you have unstable angina, you could be at risk of a heart attack. If you have pain that is getting worse or does not go away with rest or nitroglycerin, you could be having a heart attack. You should get emergency medical help right away. In this type of angina, you cannot tell what will trigger an attack. Unstable angina is more severe and usually lasts as long as 30 minutes.
No common triggers: can occur with little or no physical activity; at rest or while sleeping
Relieved by: nothing reliably relieves unstable angina. You should get emergency medical help right away

3 Variant angina
Variant angina is a rare type of angina. It happens without warning. The pain is caused by sudden tightening or spasm of a coronary artery. It most often happens at rest, between midnight and early morning. The pain can be severe.
Common triggers: emotional stress; extreme cold; smoking; use of cocaine or of medicines that narrow blood vessels; usually occurs while at rest or while sleeping
Relieved by: medicine; seek medical attention immediately
