For the majority of Coronary Artery Disease (CAD), treatment with Percutaneous Transluminal Coronary Angioplasty (PTCA) provides high initial procedural success. However, the medium to long-term complications range from rather immediate elastic recoil or vessel contraction to longer processes like smooth muscle cell proliferation and excessive production of extra cellular matrix, thrombus formation and atherosclerotic changes like restenosis or angiographic re-narrowing. The reported incidence of restenosis after PTCA ranges from 30%-50%. Such rates of recurrence have serious economic consequences. Bare Metal Stents (BMS), designed to address the limitations of PTCA, reduced the angiographic and clinical restenosis rates in de novo lesions compared to PTCA alone and decreased the need for CABG. BMS substantially reduced the incidence of abrupt artery closure, but restenosis still occurred in about 20%-40% of cases, necessitating repeat procedures. The invention of Drug Eluting Stents (DES) significantly improved on the principle of BMS by adding an antiproliferative drug (directly immobilized on the stent surface or released from a polymer matrix), which inhibits neointimal hyperplasia. The introduction of DES greatly reduced the incidence of restenosis and resulted in a better safety profile as compared to BMS with systemic drug administration. These advantages and a lower cost compared to surgical interventions has made DES an attractive option to treat coronary artery disease.

An interesting group of analysis resulted to be diabetic patients. It has been concluded that the incidence of both nonocclusive and occlusive restenosis is higher in diabetic subjects after stenting as judged from comparison with historical control subjects. Results implicate accelerated restenosis as both a consequence of diabetes and a cause for increased mortality after PCI in diabetic patient.

Therefore this observational registry has been designed for the clinical evaluation of the Orsiro LESS in diabetic subjects (Diabetic patients type 1 or 2) requiring coronary revascularization with Drug Eluting Stents (DES). Results will contribute to the collection of clinical evidence for the clinical performance and safety of the Orsiro Drug Eluting Stent System in daily clinical practice.
