Hello , This question is about my father. He is 55 yrs old and not hypertensive or Diabetic. He underwent a CABG in Feb 2010 (3.5 months ago) for multiple blockages. From the time of the surgery, he kept complaining about some pain around his chest incision. The Cardiac Surgeon who met him twice after the surgery (once after a month and then again after 2 months) said that the wound takes time to heal and hence there was nothing to worry. Just a week ago, he went to the cardiologist and got an Echo and ECG done. They turned out to be normal. However, since he again mentioned the pain which he feels around the incision (he says it pains when he shakes that part of the body, like some stiffness or tightness), the doctor asked for a TMT to be done. The TMT was done today and it says "Significant ST depression during recovery. Positive for Inducible Ischemia". What could this indicate? Should he under go an angiogram again? Any inputs will be greatly appreciated.
