Angina is chest discomfort caused by lack of oxygen to the heart muscle. It is a warning sign that there is a blood flow problem to your heart. Angina is referred to as either stable or unstable. Stable angina often happens with the same kind of activity, lasts a few minutes, and feels the same each time. Unstable angina has no pattern, no warning, lasts longer, and is more serious. Unstable angina might predict a heart attack.
