Whether arterial repair following implantation of drug-eluting stents (DES) of the second generation differs among stent types remains unknown. We examined 41 DES placed in 28 @entity1 (age 72      7  years, male 89%) presenting with stable @entity951 due to de novo lesions in native coronary arteries. Coronary angioscopy was performed 4      1  months after stent implantation. @entity1 were divided into two groups based on the DES types: 22 @entity1953 -chrome @entity2239 -eluting stents (CoCr-EES) in 13 @entity1 and 19 slow-release @entity17650 -eluting stents (R-ZES) in 15 @entity1 . Neointimal coverage (NIC) was graded as: grade 0, stent struts exposed; grade 1, struts bulging into the lumen, although covered; grade 2, struts embedded in the @entity8233 , but translucent; grade 3, struts fully embedded and invisible. NIC was defined as heterogeneous when the NIC grade variation was >= 1. Presence of @entity715 was also investigated. Distribution of dominant NIC grade (CoCr-EES: grade 0, 9%; grade 1, 77%; grade 2, 9%; grade 3, 5%; R-ZES: grade 0, 16%; grade 1: 47%; grade 2, 37%; grade 3, 0%, P  =  0.38) and heterogeneity of NIC (P  =  0.43) were similar between CoCr-EES and R-ZES groups. Existence of @entity715 was not significantly different in CoCr-EES and R-ZES (18 versus 42%, P  =  0.17). Arterial repair occurred without significant differences between CoCr-EES and R-ZES 4  months after implantation.

Comparison of early-phase arterial repair following @entity1953 -chrome @entity2239 -eluting stent and slow-release XXXX -eluting stent: an angioscopic study.
