My boyfriend had quintuple bypass surgery 2 yrs ago.He seemed to recover just fine and has had routine check ups which all seemed normal.ekg,cardiolite,several blood test.He has been noticeing some pain here and there but all test came back fine.He did have unusaul sudden pain on Sat. and ekg, blood test fine,so he had ct scan yesterday,it showed 2 of the arteries blocked. now they want to do angioplasty tuesday. he said that this is uncommon for this to happen, so soon after a bypass.Is this uncommon? and how could this happen so soon after bypass.
