6-month Intracoronary Optical Coherence Tomography (OCT) Evaluation of Three New Generation Drug Eluting Stent

6-month Intracoronary Optical Coherence Tomography (OCT) Evaluation of Endothelization and Malapposition of Three New Generation Drug Eluting Stent: CRE8, Biomatrix and Xience

Aim of this study is to compare at 6 months follow-up, endothelization and malapposition, evaluated by means of optical coherence tomography, in terms of number of struts not endothelized or malapposed, after the implantation of three new generation stent: Cre8, Biomatrix and Xience.

This is a randomized study aimed at evaluating in 60 patients with either acute coronary syndromes or stable coronary artery disease submitted with PCI and stenting, endothelization and malapposition at 6 months follow-up (primary endpoint), evaluated by means of optical coherence tomography in terms of number of struts not re-endothelized or malapposed, after the implantation of three new generation stent: Cre8, Biomatrix and Xience. Further clinical follow-up will be performed to evaluate MACE at 12 months follow-up.

Inclusion Criteria:

• Patients with stable angina or acute coronary syndromes submitted to coronary angioplasty on a coronary with a vessel diameter > 2,5 mm

Exclusion Criteria:

• Known allergy to antithrombotic drugs or to other components of the stent studied Planned surgery 6 months within angioplasty
