Brief Summary

Stents are used at centers around the world to unblock the arteries of the heart. These stents are usually made of metal and remain permanently within the blood vessel wall. Newer developments in the stent technology has led to stent scaffolds that can be reabsorbed over time. Patients with diabetes are prone to more complex blockages in the heart arteries which can be more difficult to treat. The purpose of this study is to compare the difference of how arteries heal early when metal stents or resorbable stents are used in patients with diabetes.

Secondary Outcomes (6)

  • Late lumen loss

    4 to 6 weeks

  • Neointimal area:artery area

    4 to 6 weeks

  • Strut malapposition

    4 to 6 weeks

  • In-stent restenosis

    4 to 6 weeks

  • Target lesion revascularization

    4 to 6 weeks

  • +1 more secondary outcomes

Other Outcomes (1)

  • Subgroup analysis between 4 and 6 weeks

    4 to 6 weeks

Study Arms (2)

Xience Drug Eluting Stent

ACTIVE COMPARATOR

Patients with diabetes mellitus will be randomized to receive either a Xience drug eluting stent or an ABSORB bioresorbable vascular scaffold for treatment of obstructive coronary artery disease
