Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the study is to compare strut coverage and neointimal thickness between everolimus eluting (XIENCE-V® or PROMUS® stent) and biolimus A9 eluting NOBORI Stent 14 months after stent implantation and to determine the coronary endothelial function after everolimus eluting (XIENCE-V® or PROMUS® stent) and biolimus A9 eluting NOBORI Stent 14 months after stent implantation by using supine bicycle exercise testing to assess coronary vasomotor response to exercise.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

DESIGN:

Imaging and vasomotion Substudy:

50 consecutive patients enrolled in the COMPARE II trial at the University of Fribourg Medical Center will undergo follow-up re-angiography 14 months after index procedure with assessment of Optical coherence tomography (OCT) and vasomotion testing.

ENDPOINT SUBSTUDY (all at 14 months):

Primary endpoint imaging: percentage of uncovered stent struts per lesion and mean neointimal thickness assessed by OCT.

vasomotion: coronary vasomotion assessed with quantitative coronary angiography at rest and during supine bicycle exercise.
