The COMBINE (OCT–FFR) trial is a prospective, multi-centre trial investigating the natural history of DM patients with ≥1 angiographically intermediate target lesion in three subgroups of patients; patients with FFR negative lesions without TCFA (group A) and patients with FFR negative lesions with TCFA (group B) as detected by OCT and to compare these two groups with each other, as well as to a third group with FFR-positive, PCI-treated intermediate lesions (group C).
The trial is designed to enrol 500 patients in The Netherlands, Luxembourg, Germany, Spain, Italy, Ireland, Switzerland, United Arab Emirates and Belgium.
