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

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

Detailed Description
-----------------
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.

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

Conditions
-----------------
Coronary Artery Disease

Intervention / Treatment

* Device: Cypher
* Device: Xience V


Participation Criteria
=================
Eligibility Criteria
-----------------
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).
