tight proximal disease

[Kewen]

Hi

I’ve just had a letter detailing the results of my angiogram and confused with the terminology.

Can anyone explain the term ‘tight’ as in tight proximal disease. I have had two stents fitted 17 years ago and this appears to be following the area of one of the stent s in the LAD

Many thankyous in advance for help interpreting the medical terminology
