Unstable angina is a change in your usual pattern of stable
angina. Your symptoms do not happen at a predictable time. For example, you may feel
angina when you are resting. Your symptoms may be more frequent, severe, or longer-lasting
than your usual pattern of stable angina. Your symptoms may not go away when you try
your typical ways of relieving them, such as rest or nitroglycerin.
angina is an emergency. It may mean that you are having a heart attack.
angina happens when blood flow to the heart is suddenly slowed by narrowed vessels
or small blood clots that form in the coronary arteries.
