dear dr my father has bypass surgery last year at baroda heart institute at baroda. but he has no relief at all . he has experience  pain in heart which is gradually increasing . now dr suggest him angiography . my queries is that if in angiography there is a blockage and drs said that go through angioplasty then what is the guaranty that he got relief
Angioplasty results after bypass surgery varies from patient to patient. But in general several studies revealed that there is 65-80% success rate of angioplasty in post-CABG (Bypass) patients. When these patients were followed over a period of next 30 months then about 70% of them were pain-free and had an improvement in angina. However, around 27% required repeat angioplasty with about 80% success rate while 15-20% were complicated by re-infarction and only 4-6% with cardiac death. In my opinion proceed with angiography to help determine the extent of blockage and to decide about the options available. Make sure the medications' compliance post-procedure as this is crucial. Stay blessed.
