Percutaneous Treatment of LONG Native Coronary Lesions With Drug-Eluting Stent-III (LONG-DES-III)

Percutaneous Treatment of LONG Native Coronary Lesions With Drug-Eluting Stent-III: Sirolimus vs. Everolimus-eluting Stent

This randomized study is a multi-center, randomized, study to compare the efficacy of sirolimus versus everolimus-eluting stent implantation for long coronary lesions.

Following angiography, patients with significant diameter stenosis >50% and lesion length (> 25mm) requiring single or multiple long-stent placement (total stent length >28mm) by visual estimation and eligible for LONG-DES III trial inclusion and exclusion criteria will be randomized 1:1 to a) sirolimus-eluting and b) everolimus-eluting stent by the stratified randomization method.

Inclusion Criteria:

• The patient must be at least 18 years of age.
• Significant native coronary artery stenosis (>50% by visual estimate) with lesion length of more than 25mm, which requiring single or multiple long stent placement (>=28mm)
• Patients with silent ischemia, stable or unstable angina pectoris, ad Non-ST-elevation myocardial infarction
• The patient or guardian agrees to the study protocol and the schedule of clinical and angiographic follow-up, and provides informed, written consent, as approved by the appropriate Institutional Review Board/Ethical Committee of the respective clinical site.

Exclusion Criteria:

• Any contraindication to any of the following medications: aspirin, heparin, clopidogrel, stainless steel, contrast agents, sirolimus, or everolimus.
• An elective surgical procedure is planned that would necessitate interruption of antiplatelet drugs during the first 6 months post enrollment.
• Acute ST-segment-elevation MI or cardiogenic shock
• Terminal illness with life expectancy <1 year
• Patients who are actively participating in another drug or device investigational study, which have not completed the primary endpoint follow-up period.
• In-stent restenosis at target vessel (either bare metal stent or drug-eluting stent segment, non-target vessel ISR is permitted)
• Patients with EF<30%.
• Serum creatinine level >=3.0mg/dL or dependence on dialysis.
• Patients with left main stem stenosis (>50% by visual estimate).
