stent or cabg

my husband is 58 years old, type 2 diabetic. He is asymptomatic and underwent routine Exercise test which turned out to be positive. He blockage in left descending and circumflex. He has been given the option of all 3 - medication only, stent or cabg. I would be grateful if you could advise what is the best option for him.
Looking forward to your early reply.
Thank you.

Frequently in a patient with diabetes and coronary artery disease that involves more than one vessel CABG is a good option.  If the stress test is very positive then CABG should be considered.
