OP, best of luck. I had a quintuple bypass in February and unfortunately it did not go well, but my case was very rare. These days this procedure is almost routine and you should get many more years of good quality life. But 'be your own physician". If you don't understand anything insist they explain it. Do some research and know what is being done to you and why. Having my wife and daughter around in the hospital helped me a lot as there were things I didn't have the strength to ask about or didn't remember after the surgery.
Keep riding!
