简要总结
Fractional flow reserve (FFR) is a physiologic index for the determination of ischemia-causing coronary stenosis as well as drug eluting stent (DES) optimization, even multiple anatomic imaging parameters have been widely used in clinical practice for the assessment of optimal stent procedure. Prognostic value of post-stent FFR (FFRpost) have been rarely evaluated in patient treated with 2nd generation DES. This multicentre, prospective registry was aimed to evaluate the influence of physiologic parameters on the clinical outcome after 2nd generation DES implantation.
详细描述
Patients who diagnosed obstructive coronary artery disease and treated by DES with FFR examination would be enrolled, consecutively. FFR measurement would be required at the baseline and at the end of index PCI procedure. PCI procedure would be performed upon local routine. Any available 2nd generation DES could be used. Informed consent should be obtained and protocol should be approved by each collaborator's institutional review board (IRB). Web-based electronic-case record form (CRF) system will be used for collecting data. All data will be handled and analyzed by blind fashion at independent core lab. Patient will be followed-up at each collaborator's hospital at least 2 year after index procedure. Any adverse event will be reported and addressed immediately by appropriate medical treatment to protect patient.

结局指标
主要结局
Target-vessel failure
时间窗: 2 years after index procedure
During two-year follow-up period, target-vessel failure (composite of cardiac death, target-vessel related myocardial infarction, and clinically-driven target vessel revascularization) will be evaluated. Target vessel will be defined as the treated vessel with DES which assessed by post-stent FFR. All clinical outcome will be reported according to the location of target vessel (LAD vs. non-LAD).
次要结局
- clinical, angiographic and physiologic predictors for target-vessel failure(2 years after index procedure)
