Hello Welcome to Chat Doctor You have not mentioned here why is he on warfarin. Warfarin is a blood thinner which is prescribed if a person has propensity to develop or has developed clots in the legs, in patients with irregular heart rate (AF) and in patients post valve replacement. I would be in a better position to help you had you provided the details. Coronary Angiogram is done to evaluate presence of blockages in the heart. On BAII of the findings of angiogram you may be suggested either medical management, or angioplasty or bypass surgery. Angioplasty can be done if there are short blockages on the arteries. It is a 1-3 HR procedure that can be done in the same sitting and the patient usually gets back on his legs on the next day. Bypass surgery is advice when there are multiple widespread blockages involving the major arteries of the heart. Bypass surgery requires planning, patient preparation etc. Again it takes about 4 days to patient to be back on his legs and some 20 days to recover totally. But the long term results of bypass are very good. Since he is diabetic he has a tendency to develop heart blockages so be prepared for an angioplasty if suggested. I suppose I have answered your queries satisfactorily. Wishing him good health. Regards
