PRESTIGE: PREvention of Stent Thrombosis by an Interdisciplinary Global European Effort

Study Overview
=================
Brief Summary
-----------------
The PRESTIGE-registry is a joint effort at 9 European heart centers to collect data regarding patients presenting with stent thrombosis in a dedicated database. There will be extensive clinical and procedural characterization, furthermore blood platelet function testing, intracoronary imaging, DNA-sampling and analysis of thrombus aspiration will be performed.

Detailed Description
-----------------
Rationale: Stent Thrombosis (ST) is a serious complication of percutaneous coronary intervention (PCI) with stent implantation. Previous studies have been hampered by small sample size, in particular regarding the number of patients with late and very late ST and patients with DES thrombosis, and by incomplete patient characterisation, particularly concerning intracoronary imaging and blood platelet function data. Objective: to identify novel predictors and to observe clinical outcome after an episode of ST, with the use of state-of-the-art new techniques such as OCT/IVUS, platelet function testing, genetic analysis. Study design: multicenter matched case control study Study population: Cases: all patients presenting with definite ST. Expected number of patients to be included: 2000 Controls: patients undergoing PCI will be matched based on the following criteria: Expected number of patients to be matched: 2000 who underwent a PCI for the same indication who underwent a PCI on the same date (±5 days) who underwent a PCI in the same interventional centre Main study parameters/endpoints: clinical, ECG, biochemical, angiographic, procedural, haematological, histopathological, genetic, OCT/IVUS-imaging, and follow-up characteristics Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Prior to PCI, 50 ml of whole blood will be drawn from all patients. Primary PCI for ST will be performed according to institutional best practise. During PCI, performance of Optical Coherence Tomography and/or Intravascular Ultrasound is encouraged. Thrombus aspiration is performed when indicated. During hospitalisation, all patients will be asked to fulfil a questionnaire regarding possible triggering mechanisms that might have provoked the ST. Patients will be asked to visit the patient clinic for platelet function 30 days after the acute phase of the ST. Finally, patients will be contacted for follow-up details.
