Triple vessel cornary disease with 3 blockages, what are his options other than triple bypass surgery?

Cardiac cripple: To understand the risk/benefit of recommended bypass, start with the risk of non-operative therapy. With medical therapy alone, the risk for ischemic damage to the heart muscle is real. This can lead to death or weak heart muscle, aka cardiac cripple. The surgical risk is real, but lower than non operative risk. Bypass preserves the heart muscle and you stay on medication. Ok to ask your surgeon.

Few: Why so much at 33? Smoker obese diabetic, family positive history? Depending on all the risk factors, coronary grafting is likely the best option along with best behavior and cardiac rehab. Some few stenting may be possible and delay.
