I have a male friend who had a massive heart attack 2 yrs ago, and underwent triple bypass. He was told his heart is only functioning at 25-30%. He is 60 y/o now. His father and uncle both died from massive heart attacks. Can he live a normal life expectancy?
Thanks for your question on Chat Doctor. I can understand your concern. At the age of 60 years with triple vessel bypass in the past, 25-30% heart function is acceptable. Usual life expectancy of bypass surgery is 10-15 years. So your friend will have normal life for at least 10 years if he is following optimal cardiac Care, dieting and cardiac supportive Chat Doctor.  After 10 years, he may need revision surgery or stenting if he develops blockage in coronary arteries. So at present, you can expect 10 years of life expectancy for your friend with optimal cardiac Care. Hope I have solved your query. I will be happy to help you further. Wishing good health to your friend. Thanks.
