Thanks for writing in.
If you do not have any symptoms right now, this procedure (catheterization) can wait. However, if you have symptoms like chest pain
and breathlessness with exertion, I would suggest you get it done as soon as possible.
Since you are at increased risk of a heart attack
, the sooner it is done , the better it is. A heart attack can lead to an irreversible loss of heart muscle and can lead to serious complications later on.
Please get it done as soon as possible.
Hope this helps
