Characterize the complex biological mechanisms and sequential cellular phases underlying arterial restenosis following percutaneous transluminal coronary angioplasty.
Pathophysiological review evaluating vascular reparative responses to balloon angioplasty injury.
Synthesis of cellular interactions, local tissue substrates, and growth factor cascades driving luminal narrowing.
Restenosis follows a tripartite sequence comprising elastic recoil, local thrombosis, and smooth muscle cell activation paired with extracellular matrix synthesis.
Vessel renarrowing is driven by pre-existing tissue substrates alongside growth factors derived from thrombus, arterial walls, and circulating cells.
