Pathological evaluation of predictors for delayed endothelial coverage after currently available drug-eluting stent implantation in coronary arteries: Impact of lesions with acute and chronic coronary syndromes.

Endothelial coverage was limited at 90 days after currently available DES implantation, and the ACS culprit site and circumferentially durable polymer-coated DES were identified as independent predictors of delayed endothelial coverage. Our findings suggest the importance of underlying plaque morphology and stent technology for vessel healing after such implantation.
