I had two 90% blocked LAD branches stented two years ago. They were recently checked and found to be still patent.
The main LAD segment however has remained 30% blocked, ie it is 70% open.
 I understand that any blockage 50%< will not be stented by any cardiologist, as a coronary artery that is blocked 50% or less is "not viewed as being physiologically significant".
My question is: if in theory that 30% LAD blockage was suddenly unblocked, would I notice any difference at all in eg running up stairs or playing tennis ie is there really no perceptible difference under normal loads for the average person between an LAD that is 100% open and one that is 70% open?

Good Morning, great question but beyond my scope of knowledge for sure. Your best resource would be your caridologist.

Perhaps another member will have an answer for you.

Take care,
