if you think about coronary arteries, I know there are only few anastomoses which are not enough so coronary arteries are always treated as terminal blood vessels (all organs have terminal blood vessels: the brain,the heart, the kidney...)

Yes,but sometimes,even the progresive coronary AS does not result in an ictus cordis or even in an infarction-because anastomoses develop and they bridge the proximity of the occluded coronary arteries to the distal,unocluded ones.I have seen clinical cases with 95% of occlusion but survived thanks to the anastomozes.
They are developing in a long time course-as the AS progresses(not overnight) and another very important point:It is very individual.I suppose some people have better angiogenesis potential than the others(more growth factors,specific molecular targets etc).
In animals,you can actually stain the tissue with laminin and see only the newly formed vessels,expressing this type of a molecul.
My two cents...
