What you wrote in your Medpedia "My Profile" is probably more informative ("I had my first bypass in 1996, at least 3 angioplasties since. I now get chest pain quite badly when I travel - on flight and walking."). If the current chest pain is familiar but a recent recurrence, your cardiologist should be promptly notified. Yes, diminished oxygen levels and increased oxygen consumption can precipitate the angina (coronary insufficiency) symptom. ..Maurice.
