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.
