[|Human|] My husband is a 57 year old, who is not over weight, is very active, and works out at least 4 times a week.  He underwent triple bypass surgery 10 months ago and recovered quickly with no damage to his heart, but now is experiencing episodes where he feels tightness in his chest (so tight it is almost painful), and his arms get extremely weak.  This only lasts a couple of minutes, but the episodes leave him feeling drained.  They are random, and are always following exertion.  He had these symptoms before the bypass, and we thought they may have been caused by his condition, but he is having them again?  Another odd symptom he just recently had was extreme fatigue after walking around in the mall for just a few hours (had to set down, felt like his legs were going to give out on him).  Could they have missed a blockage, or could there be another one so soon?
[|AI|]  Howell come to ChatDoctorI really appreciate your concern, it is the 10 months gone since the bypass done so the chances of developing the ischemia (Coronary artery) would be very likely, and it needs to be ruled out and for that may need step by step investigation like EKG, ECHO, STRESS test SOS, and important is coronary angiography test else missing the block is not possible hope this information helps.
