Coronary Artery Stenosis
Conditions
Keywords
significant stenosis (>70% of lumen stenosis), epicardial coronary arteries.
Brief summary
Sirolimus-eluting stent (SES) has been world-widely used in clinical practice in treating patients with coronary artery disease (CAD). The efficacy and safety of Cypher SES (Cordis, MA) has been proved by several randomized clinical trials. Here the investigators design a prospective, multicenter, randomized clinical study in purpose of identifying the non-inferiority in the efficacy and safety in treating CAD patients by Firebird 2 SES (Microport, Shanghai), comparing with Cypher SES.
Interventions
DEVICEFirebird 2 SES
The FIREBIRD2™ Rapamycin-Eluting CoCr Coronary Stent is the second generation DES of MicroPort, which based on the new cobalt chromium alloy stent platform. It uses polyolefin polymer, which makes the coating property very remarkable.
DEVICECypher SES
The Cypher SES is based on the 316L platform with Controlled-release, nonresorbable, elastomeric polymer coating.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| in-stent late lumen loss at 9 months' angiographic follow-up | 9 months | Late luminal loss was defined as the difference between the minimal luminal diameter immediately after the placement of the stent and the minimal luminal diameter at 9 months |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| target vessel failure | 1, and 2 years after index procedure | defined as the occurrence of any of the following within 1 and 2 years after the index procedure: death from cardiac causes, Q-wave or non-Q-wave myocardial infarction, or revascularizationof the target vessel (emergency or elective coronaryartery bypass grafting \[CABG\] or repeated percutaneous transluminal coronary angioplasty \[PTCA\]). |
