My father has got severe heart attack last month. After angiography, it was found that he has multi vessel heart blockage and hence have been asked for bypass surgery. He is 70 yrs old with No sugar or diabetes. Currently he is not ready for the surgery. We wanted your opinion Dr if he can still continue without having bypass surgery taking all the medications. What is his life expectancy with and without surgery. Also let us know precautions which we should take. He has been prescribed with aspirin tab, bp tab and cholesterol tab. Kindly advise.
