Which is better stent or byepass in a diabetic patient?

In diabetes: The narrowing a can be more diffuse, presenting challenges for both. Has to be taken on a case by case basis.

Depends: Hi. It depends on the anatomy: which coronary artery/arteries, distal targets, etc. Assuming the cardiologist and CT surgeon are experienced, they will explain options and make a recommendation based on experience. No simple answer unless it's left main disease.
