How long does bypass surgery last?

My dad had a quadruple bypass operation in 1994 when he was 44 years old

He's currently fit and well other than angina which is getting worse

My parents historically keep their medical problems to themselves as they don't like people to needlessly worry so they waited until the day of cancer surgery to mention that my mum had cancer for example

At the weekend I had to take him to minors as he'd managed to put the spade through his boot and into his foot whilst in the garden, scar on his leg was noticed and he was asked when his surgery was

When he told them the response was 'oooo you've done well!'
This reaction, coupled with the increase in angina means i'm worrying -should I be?

No idea, it's under control according to him

I know he has regular GP appointments and takes statins but other than that he keeps things to himself

20 years is quite a long time after bypass surgery with no further problems, so he has done pretty well, but if he is having more angina he needs to be seen by a cardiologist again. The grafts don't have an "expiry date" on them but as with any blood vessels, they are prone to getting more diseased as you get older.
