This multicenter, prospective, observational registry will assess efficacy and safety outcomes associated with percutaneous coronary intervention (PCI) with implantation of the CYPHER Select™+ Sirolimus-eluting Coronary Stents in Chinese diabetic patients with coronary artery disease in routine clinical practice.

The study objective is to assess the incidences of major adverse cardiovascular events (MACE; defined as a composite of clinically driven target-lesion revascularization, cardiac death, any myocardial infarction, and stent thrombosis) at 12-month follow-up, and of stent thrombosis at 1-day, and 1- and 12-month follow-up. Pre-specified analyses will be performed among patient subpopulations according to level of glycemic control (HbA1c level < 6.5% or > 6.5%); reference vessel diameter by quantitative coronary angiography (< 2.5 mm and > 2.5 mm); and stented length (8-18 mm; 23-33 mm; and >33 mm). Quantitative coronary angiographic (QCA) analysis will be performed at the core lab of the China Cardiovascular Research Foundation for all pre- and post-index procedure angiograms and during the 12-month follow-up period for the pre- and post-reintervention procedures in those cases of clinically-driven PCI revascularization. Also, multivariable analyses will be conducted to investigate potential predictors of 12-month MACE rate in routine clinical practice.

The registry will be conducted at about 45 centers in China, where the CYPHER Select™+ Sirolimus-eluting Coronary Stent is commercially available. Data will be collected on 2,500 diabetic patients treated with the CYPHER Select™ + Sirolimus-eluting Coronary Stent only.

Primary outcome: MACE (clinically driven TLR, cardiac death, MI, ST) at 12 months Secondary outcome: ARC (probable + definite) ST at 1-day, and 1 and 12 months

Inclusion Criteria:

• Patients between the ages of 18 and 80 (inclusive) receiving CYPHER SELECT™+ Sirolimus-eluting Coronary Stent according to standard clinical practice when financially feasible
• The patient or guardian agrees to the study protocol and the schedule of clinical follow-up, and provides informed, written consent, as approved by the appropriate Institutional Review Board/Ethics Committee of the respective clinical site.
• Patient has diagnosis of diabetes or is diagnosed with it before or during the index procedure hospitalization based on disease diagnosis criteria

Exclusion Criteria:

• Any contraindication to any of the following medications: aspirin, heparin, thienopyridines (clopidogrel/ticlopidine), stainless steel, contrast agents, or sirolimus
• An elective surgical procedure is planned that would necessitate interruption of antiplatelet drugs during the first 6 months post enrollment
• Cardiogenic shock
• Terminal illness with life expectancy <1 year
• ST-segment elevation myocardial infarction within 7 days prior to the index procedure
• Any patient who received coronary stent(s) within 1 year

The registry will be conducted at approximately 45 centers in China where the CYPHER SelectTM+ Sirolimus-eluting Coronary Stent is commercially available. Data will be collected on 2,500 diabetic patients treated only with the CYPHER Select™+ Sirolimus-eluting Coronary Stent during the index procedure. Enrolled diabetic patients are confirmed and diagnosed with Diabetes before or during the index procedure hospitalization, i.e., those receiving active treatment with an oral hypoglycemic agent or insulin, patients with diagnosis of diabetes who were on dietary therapy alone or patients with an abnormal blood glucose level after an overnight fast as defined by local standards.
