What is acute coronary syndrome? syndrome happens when the heart
is not getting enough blood. It is an emergency. It includes
unstable angina and coronary arteries supply oxygen-rich blood
to the heart muscle. If these arteries are narrowed or blocked,
the heart does not get enough oxygen. This can cause angina or a
heart attack. - Unstable angina is chest pain or discomfort from
lack of blood flow, but there is no damage to the heart muscle.
It often happens when you are at rest. You may have had stable
angina before. You knew when to expect your symptoms, such as
when you exercised. Stable angina usually goes away when you
rest or take your angina medicine. But the symptoms of unstable
angina may not go away with rest or medicine. It may get worse
or happen at times that it didn't before. Unstable angina is not
a heart attack. But it is a warning that a heart attack could
happen soon, so it needs to be treated right - A heart attack
means a coronary artery has been blocked and the heart has been
damaged. Wi
