[|Human|] My brother had a heart attack 1 month ago still is suffering from severe shortness of breath had 4 stents put on his right side of the heart was just told on friday his heart is working at 35% I know this is very serious what are his chances for long term survival. Bypass surgery? He is 58 a smoker 250 lbs 59 hasnt seen a doctor in 10 years
[|AI|]  Hi35% is a critically lower section fraction but post PTC things are going to improve as blood supply is again maintained to heart, there are medicines like ace inhibitor, trimetazidine and spironolactone which prevent cardiac remodeling and hence helps to improve the ejection fraction, power if things worsen AID can be given. Chances of survival are from 10 years to 30 years depends on medication, lifestyle modification and patency of stents., by pass surgery at an EF of 30% has five year survival rate of 70%
