Coronary artery disease is a degenerative disease that means even if you had a healthy lifestyle, it has other contributing factors like being male, age, family history of CAD, and gene mutation which can cause CAD, which are non modifiable risk factors and as age gets older, Disease also gets progressively worse

Based on that which is more beneficial for the patient doctor will advise for that option, although CABG IS BEST TREATMENT FOR CAD, we still need to look for other factors as patient is feasible for surgery or not, you take the CTVS Opinion they will help you out.
