Get a second opinion. Have someone else look at your catheterization. Make sure you bring the actual film to the visit. Depending on the location of the blockages, your age and the presence of other comorbid conditions such as diabetes or heart failure are taken into consideration when deciding on one modality versus the other. If you aren't diabetic or have heart failure, or are very young, I would say that stenting is the better option, not because of better long term outcome because those are equivalent between bypass and intervention, but because the procedure doesn't entail opening your chest and undergoing major cardiovascular surgery.
