What do you recommend if i had a heart angiogram with 70% blockage in my left main coronary artery.no stint.dr afraid he would block.why?

Bypass surgery: everything is a balance between risk/benefit. often with a > 50% left main blockage, a bypass surgery is the safest choice. medical therapy alone carries a high risk of sudden death due to the severity of the blockage. a stent placement there, though relatively simple - might have a catastrophic outcome if any slight thing went wrong. a stent is indicated if surgery is higher than usual risk.
