My angina has begun during exercise to reoccur approximately six years after having stents. It is very predictable and goes away after about a minute of rest.
After a 30 to 45 minute period of brisk walking with several occurrences of mild predictable angina and required rests, I experience no more angina. This is true even when walking briskly up steep hills.
What might be happening to cause the angina pain go away after this initial warm-up period?
