How is variant angina related to a heart attack?

The cause of variant angina is a coronary artery spasm. This causes blood flow to the heart to slow or stop. Even though the spasm is temporary, the longer the spasm lasts, the longer the heart goes without enough blood flow. If the spasm lasts long enough, it can cause a heart attack.

In addition, both variant angina and heart attacks cause sudden chest pain. Since it is hard to tell the difference, the best ting to do is go to the emergency room.
