Filter by:This is a multi-center, single-blind, randomized, active-controlled, clinical trial in Percutaneous Coronary Intervention (PCI) subjects. Subjects will be randomized to receive the Combo stent as the investigational treatment arm or an Everolimus Eluting Stent (EES) as the active-control arm.
Prasugrel and ticagrelor were both associated with a significant reduction in the risk of MACE in patients undergoing PCI for an ACS, mostly through a reduced stent thrombosis. The 1-year relative risk reduction (RRR) of definite of probable stent thrombosis in patients receiving a DES were fairly different in TRITON-TIMI 38 and PLATO trials. The incidence of "biologically active" stent (DES or BVS) thrombosis is largely variable according to different lesion settings. We aim to verify the translation of the postulated different reduction in thrombosis rate among various P2Y12 inhibitors (clopidogrel, prasugrel and ticagrelor) in a high-risk setting such as the PCI with DES or BVS in CTO and bifurcating lesions.
To demonstrate the incremental utility of SSF for individuals undergoing CCTA, with expected improvements in image quality and diagnostic accuracy.
Background: - Magnetic resonance imaging (MRI) is type of imaging study that uses magnetic fields and radio waves to take pictures of the body. To help the images show up more clearly, a contrast agent is injected into a vein. Researchers are interested in finding contrast agents that can help show problems with the blood vessels around the heart. They want to test an agent called Gadofosveset Trisodium to see how it works in MRI scans. Objectives: - To test the effectiveness of Gadofosveset Trisodium as a contrast agent in heart MRI scans. Eligibility: - Healthy volunteers between 18 and 45 years of age. Design: - Participants will be screened with a physical exam and medical history. They will provide blood samples before the scanning sessions. - Participants will have an MRI scan after the screening visit. They will have a dose of the contrast scan before the study. - Participants will return for one additional MRI scan within 1 to 2 months of each scan. Different doses of the contrast agent will be used for each scan. - An additional blood sample will be collected within 1 week of the second MRI scan.
The purpose of this study is to investigate the effect of omega 3 on biomarkers of cardiac necrosis(CKMB and troponin I) and inflammation marker CRP.
This is a prospective, randomized study conducted in patients undergoing coronary revascularization procedures (PCI) through angioplasty. All patients who meet the eligibility criteria will be randomized to receive, before the procedure, an oral aspirin reload (325 mg) and to be re-evaluated at 60 minutes, 120 minutes, 6 hours, 48 hours, 5 and 30 day, 3 and 6 months.
The purpose of this Clinical Evaluation is the continued assessment of the XIENCE Everolimus Eluting Coronary Stent System (XIENCE V® and XIENCE PRIME™ EECSS) with the primary focus on clinical outcomes in the treatment of female patients with de novo coronary artery lesions, and the characterization of the female population undergoing stent implantation with a XIENCE stent.
The purpose of the study is to evaluate diagnostic performance of high iodine (iopamidol 370 mg/dl) content versus low iodine (iodixanol 300 mg/dl) content for diagnostic accuracy by contrast-enhanced Coronary Cardiac Computed Tomography (CCTA) using a 64-detector-row CT scanner for detection of presence or absence of coronary artery obstruction when compared against invasive coronary angiography, the standard of truth.
The purpose of this study is: To evaluate the safety and performance of the Presillion stent in routine clinical practice.
The specific objectives of this thesis are in a cohort of patients with an acute ischemic stroke, 1. To establish the degree of coronary arteriosclerosis. 2. To describe left ventricular systolic and diastolic function in relation to changes of NT-proBNP.
