A member asked:
When cto of lad is opened does collateral flow to cells fed from rca shrink and do those cells suffer from less capillary flow? sure they're reached?
A doctor has provided 1 answer
Better: When coronary flow is established by opening an occluded artery,collaterals to the region disappears.Blood flow through collaterals is only a fraction of the normal but enough to maintain viability of some heart cells but barely.These cells are "hibernating" and when normal flow is restored they can return to functioning normally again
