Filter by:The aim of the study is to assess continued safety and efficacy of the SeQuent® SCB. The product under investigation will be used in routine clinical practice according to the latest European Society of Cardiology (ESC) guidelines and according to the Instructions for Use (IFU). Those data that are obtained in routine clinical use will be documented in the Case Report Form (CRF).
This is a prospective registry to enroll complex high-risk coronary heart disease patients. The purpose of this study is to compare intracoronary physiology and imaging-guided intervention strategy and angiography-guided intervention strategy for clinical outcomes and health economics.
The optimal antithrombotic management in patients with coronary artery disease (CAD) and concomitant atrial fibrillation (AF) is unknown. AF patients are treated with oral anticoagulation (OAC) to prevent ischemic stroke and systemic embolism and patients undergoing percutaneous coronary intervention (PCI) are treated with dual antiplatelet therapy (DAPT), i.e. aspirin plus P2Y12 inhibitor, to prevent stent thrombosis (ST) and myocardial infarction (MI). Patients with AF undergoing PCI were traditionally treated with triple antithrombotic therapy (TAT, i.e. OAC plus aspirin and P2Y12 inhibitor) to prevent ischemic complications. However, TAT doubles or even triples the risk of major bleeding complications. More recently, several clinical studies demonstrated that omitting aspirin, a strategy known as dual antithrombotic therapy (DAT) is safer compared to TAT with comparable efficacy. However, pooled evidence from recent meta-analyses suggests that patients treated with DAT are at increased risk of MI and ST. Insights from the AUGUSTUS trial showed that aspirin added to OAC and clopidogrel for 30 days, but not thereafter, resulted in fewer severe ischemic events. This finding emphasizes the relevance of early aspirin administration on ischemic benefit, also reflected in the current ESC guideline. However, because we consider the bleeding risk of TAT unacceptably high, we propose to use a short course of DAPT (omitting OAC for 1 month). There is evidence from the BRIDGE study that a short period of omitting OAC is safe in patients with AF. In this study, these patients are treated with DAPT, which also prevents stroke, albeit not as effective as OAC. This temporary interruption of OAC will allow aspirin treatment in the first month post-PCI where the risk of both bleeding and stent thrombosis is greatest. The WOEST 3 trial is a multicentre, open-label, randomised controlled trial investigating the safety and efficacy of one month DAPT compared to guideline-directed therapy consisting of OAC and P2Y12 inhibitor combined with aspirin up to 30 days. We hypothesise that the use of short course DAPT is superior in bleeding and non-inferior in preventing ischemic events. The primary safety endpoint is major or clinically relevant non-major bleeding as defined by the ISTH at 6 weeks after PCI. The primary efficacy endpoint is a composite of all-cause death, myocardial infarction, stroke, systemic embolism, or stent thrombosis at 6 weeks after PCI.
The primary aim of this study is to establish how frequently patients with coronary artery disease present or develop two anxiety disorders (panic disorder and generalized anxiety disorder) in the two years following a medical intervention for their heart. A second objective is to assess the impact of these anxiety disorders on the health of these patients.
Prospective clinical study with two parts: PART A: a prospective biomarker-based risk screening study in coronary heart disease (CHD) subjects PART B: a nested randomized clinical trial (RCT) in an enriched subpopulation of high-risk stable CHD subjects PART A: 12 000 subjects with stable CHD PART B: 2000 subjects with high risk of CV events will be randomized to usual care (UC) or personalised prevention program (PPP) i.e. 1000 subjects per arm. Study purpose is to assess the clinical value and cost-effectiveness of a personalised prevention program (PPP) in high-risk, stable coronary heart disease (CHD) subjects and to prospectively validate risk screening biomarkers
The aim of this study is to record hemodynamic pullback information using continuous resting full-cycle flow ratio (RFR) and fractional flow reserve (FFR) in patients with diffuse coronary artery disease. The capacity of the two indexes to predict the hemodynamic outcome after stenting will be compared. Goals of the study are: - To study the accuracy of RFR/FFR gradients in predicting the change in whole-vessel RFR/FFR after PCI. - To identify a threshold in the RFR/FFR gradient that is predictive of pathological RFR/FFR also after the PCI of the first lesion.
Multivessel TALENT is a prospective, randomized, multi-center study comparing clinical outcomes between SUPRAFLEX Cruz and SYNERGY in approximately 1550 patients with de-novo three vessel disease undergoing percutaneous coronary intervention (PCI). Patients will be treated according to "state of art PCI"; not only treatment strategies based on the latest ESC guideline, such as SYNTAX Score II recommendation, Heart Team discussion, post-procedure intravascular imaging optimization, cholesterol reduction by statin or PCSK-9 inhibitor, but also exploratory treatment strategies based on the latest evidence, such as physiological assessment using quantitative flow ratio and prasugrel monotherapy following 1-month dual antiplatelet therapy after PCI.
Percutaneous cardiovascular intervention procedures (e.g. coronary angioplasty, peripheral artery angioplasty) must be performed in person, requiring the physical presence of one or more medical, nursing and technical professionals. The control of catheters and interventional materials is performed manually, with the operator positioned next to the patient. This context results in potential for reciprocal exposure to exhaled air, both for the professionals involved and for the patient, with an inherent risk of aerial contamination. It is important to note that interventional procedures are often performed on an urgent or emergency basis (e.g. myocardial infarction), without the possibility of postponement or postponement. The recent robot-assisted cardiovascular intervention makes it possible to modify this scenario by allowing the procedure to be performed effectively and safely in a position far from the patient. In an environment with high potential for contamination, mainly related to the current pandemic caused by the COVID-19 virus, may prove to be a tactic to expand hospital security. It is in this sense that the present pilot proposal is inserted, which, ultimately, aims to evaluate the potential of robotic intervention as a strategy to reduce exposure to exhaled air of patients and professionals during the intervention procedure.
To assess the rates of ischemic and hemorrhagic complications of long-term antithrombotic therapy in patients with chronic coronary syndromes
This study is being conducted to provide access to and collect test data for an established nuclear medicine diagnostic imaging test called Positron Emission Tomography (PET), using a specific radioactive drug called Ammonia N-13 (Ammonia), referred to simply as an Ammonia PET scan, which is used to visualize the blood flow through the blood vessels and into the heart muscle in order to identify areas of restricted blood flow within the heart. The scanner used in this study may be a stand-alone PET scanner or a PET/CT scanner, which combines the PET scanner and a Computed Tomography (CT) scanner into a single device. Unless otherwise stated in this consent form, the term PET will be used to refer to both stand-alone PET and PET/CT scanners. While physicians have used the Ammonia PET test for many years to visualize (image) the blood flow into the heart muscle (perfusion), it is now possible to also measure the flow of blood into the heart muscle. Research studies have demonstrated clinical value in reviewing the measured blood flow values in addition to reviewing the perfusion images of blood flow into the heart muscle. Therefore, this study will establish a database of a large number of Ammonia PET measured blood flow values to serve as a future reference.
