Additional Info

Angina pectoris is chest pain due to cardiac ischemia. It can take on many patterns, and those patterns may not always be the same.
What makes angina stable is that: (a) it comes on only with exertion that increases body oxygen demand -- typically exercise, and (b) it comes on predictably and reproducibly with the same amount of exertion, and (c) it goes away with rest or treatment (e.g. sublingual nitroglycerine).
If it comes on with rest, or over time has been coming on with LESS exertion, than it is not stable, but unstable angina.
