Hi, I'm 57 yr old, male, I have bypass surgery scheduled for the next Friday. As it was shown in catheterization results, I have one artery fully blocked and the other one is 30-40% blocked, The heart is fed through three vessels from that other artery. My doctor told me that stent is impractical in my case and advised me for bypass surgery. He also told me that it's not "a question of life and death", but rather "of quality of life", that I will be able to lift weights, etc. But now, I'm pretty satisfied with my current QOL, I breath freely, can walk, even do light to medium-hard exercise. After the pre-admission debriefing I had this Friday, I'm starting to have second thoughts. If it's not a life/death question and with possibility of all those post surgery side effects, incl. liver failure (20%) or stroke (20%), do I really need to have this surgery right now? Aren't the risks too much in comparison with the results (higher QOL)?
