Well the answer to your questions would depend on lot more factors but from the information you have given he does need the following drugs for Post MI - Asprin, Clopidogrel
. for his diabetes
it depends on his control, get done a HbA1c
(if not done already) and let me know. If he is well controlled on oral drugs, i would go with that but if not i would advice a switch to insulin
. An echocardiography
is recommended, since he is diabetic i would advice a coronary angio and further mx could be planned after that.
