About this trial
This is an interventional diagnostic trial for Coronary Artery Disease focused on measuring drug-eluting stent, coronary endothelial function, coronary imaging
Eligibility Criteria
Inclusion Criteria:
- Patient enrolled in the COMPARE II trial with successful stent implantation and absence of binary restenosis or severe progression of coronary artery disease at 14 months follow-up.
- Patient consent to undergo a non-scheduled follow- up angiography with imaging study and bicycle exercise testing
Exclusion Criteria:
- Inability to provide informed consent
- Inability to perform a supine bicycle exercise stress test
- Binary in stent restenosis of the target vessel
- Acute Coronary Syndrome, Acute Myocardial Infarction
- Patients with stent thrombosis following the index procedure
- Female of childbearing potential ( age ≤ 50 years and last menstruation within the last 12 months ), who did not undergo tubal ligation, ovariectomy or hysterectomy
- Known intolerance to heparin, contrast material
- History of bleeding diathesis or known coagulopathy
- Age ≥ 80 years
- Hemodynamic instability
- Renal failure (creatinine clearance ≤ 40 ml/min)

5. Study Description
Brief Summary
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
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.
