[|Human|] hi, Its been a year since my dad had an angioplasty .Sometimes he would walk even half a kilometre without getting tired but most of the times he gets completely exhausted within 100 metres and can walk no further.There seems no reason why he is tired on some days and not on other days.He was a heavy smoker before heart attack.He is on medicines and diabetic.His all other levels are normal except HDL it is 35.I suspect he has developed more blockages....is it possible
[|AI|]  HIF stents are not successful, they may decorate cardiac functions, I would advise you to have a 2d echo as early as possible to rule out the cardiac function s, severe fatigue and in ability to do even normal work can indicate a problem with heart pumping 2d echo is must diagnose the functioning of heartier angioplasty echo should be compared by angiogram now to rule pout the decoration of his cardiac function or possibility of new blockages
