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.

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.

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.

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 purpose of this study is to analyze the data of patients who underwent FFR evaluation at CAVHS to evaluate the impact of PCI on coronary hemodynamics in patients with baseline ischemic FFR, the potential etiologies of suboptimal FFR post PCI, determine potential measures taken to correct persistently suboptimal FFR and PCI, and determine rate of clinical events, utility of routine Post PCI FFR strategy compared to pre PCI FFR strategy only, and evaluate the "Warranty Period" of non-ischemic FFR in different sub groups.

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.

EVOLVE 4.5/5.0 is a prospective, single-arm, multi-center observational (standard of care) trial intended to confirm the safety and effectiveness of the SYNERGY 4.50 mm and 5.00 mm Coronary Stent System for the treatment of patients with coronary artery disease in large vessels (≤ 28 mm in length, by visual estimate, in native coronary arteries > 4.00 mm to ≤5.00 mm in diameter, by visual estimate). This Post Approval study is a cohort associated with the SYNERGY MEGATRON Post Approval Study, which is registered under ClinicalTrials.gov ID: NCT04807439.
