Active clinical trials for "Coronary Artery Disease"

TruePhysio pressure microcatheter is a novel device for evaluating the functional significance of coronary stenosis, and its safety and efficacy on the measurement of hyperemic index have been validated in the previous SUPREME study (NCT03541577). This study will further evaluate the safety and efficacy of the physiological indices measured by the TruePhysio pressure microcatheter, including resting and hyperemic indices, with respect to the physiological indices measured by the Pressure Wire.

The purpose of the current study is to demonstrate non-inferiority of everolimus-eluting bioresorbable vascular scaffold to everolimus-eluting stents in patients with chronic total occlusion regarding the antirestenotic efficacy at 8 to 10-month angiographic follow-up.

This prospective randomized clinical trial aims to compare two different "metal-free" strategies for elective percutaneous coronary revascularization: the FFR-guided DCB-only PCI (drug-coated balloon: SeQuent Please™, B Braun Melsungen GmBH) vs. OCT-guided BRS implantation (bioresorbable scaffold: Absorb™, Abbott Vascular).

The purpose of this study is to evaluate the relative effectiveness and safety of Bioresorbable Vascular Scaffold compared to other (drug eluting stents) DES.

Most previous trials support the absolute increase in bleeding risk with perioperative administration of antiplatelet. Furthermore, recent studies demonstrated that perioperative major bleeding may be related to increase cardiovascular risk. The investigators will compare the efficacy and safety of continuing versus stopping antiplatelet therapy during perioperative period in patients underwent PCI(Percutaneous Coronary Intervention) with next generation DES(Drug Eluting Stent).

The purpose of the study is to investigate the extent of ischemia and left ventricular function in cardiovascular magnetic resonance (CMR), as well as patency of coronary arteries and grafts in coronary computed tomography angiography at 12 months follow up in patients with advanced coronary artery disease treated with percutaneous coronary intervention with the implantation of bioresorbable scaffolds or coronary artery bypass graft surgery. Additionally, the clinical results of the two methods of revascularization will be carried out annually up to 5 years.

The DuraGraft® Registry is a European registry of patients who have undergone CABG and whose vascular grafts have been treated with DuraGraft. All participating sites will be from countries in Europe. The DuraGraft Registry will collect pre-CABG, intraoperative and post-operative data, major post-CABG cardiovascular adverse events, health economic outcomes and patient reported quality of life over a period of 5 years.

Clopidogrel is a prescription medicine used to minimize blood clot formation in patients with cardiovascular disease, particularly those undergoing heart catheterization and stroke. A substantial amount of medical evidence has proven that patients with stroke or heart diseases can benefit from this medicine. However, significant variability in such expected benefits has been found among individuals receiving clopidogrel, with some patients not having the benefit of reduced complications and adverse cardiovascular events. Prior studies have demonstrated a significant association between certain variants on patient's genes (e.g., CYP2C19) and poor response to clopidogrel and, therefore, major adverse cardiovascular events. Variation in other genes and other factors such as platelet activation, weight, diabetes mellitus (a medical condition that produces high blood sugar), concomitant use of other drugs, and smoking status have also been proposed to be related to the same adverse outcomes. In this study, the investigators would like to determine a possible association between these genes and the response to the medication among Caribbean Hispanic cardiovascular patients on clopidogrel. In other populations, it is known that patients with certain genetic variants have lower or magnified responses to this medication when compared to those individuals taking the same dose and not carrying the genetic variations. However, a fundamental gap remains in understanding whether the genomic diversity of Caribbean Hispanics accounts for the observed high inter-individual variability of clinical outcomes to preventive dual antiplatelet therapy (DAPT) with clopidogrel.

The purpose of the study is to see whether the antibiotic combination of 100mg doxycycline, 500mg azithromycin and 300mg rifabutin is a safe and effective treatment for coronary artery disease which has not responded to 'standard treatment'. Coronary artery disease is the process of plaque build up within the walls of the arteries responsible for supplying the heart with oxygen and nutrients. plaque is usually made up of fatty deposits, minerals and various amounts of tissue and white cells which eventually narrows the artery, reducing blood flow to the heart. The resulting damage and build up of fat leads to inflammation of the arterial wall and eventually the arteries narrow. The researchers involved in this study consider that a pathogen called Chlamydophila pneumoniae, which can live inside cells may cause this inflammation of the arterial wall. The purpose of this study is to see if treatment with this antibiotic combination in patients with CHD is safe and effective in reducing disease severity measured at coronary angiography and improving quality of life. Approximately 60 patients will be involved in this trial. the treatment period is 90 days with a further 90 day follow up period.

The aim of the study is to assess the safety and efficacy of the device to treat coronary de novo and restenotic lesions.
