Filter by:Psoriasis is an inflammatory disease involving the skin, the joints and the vascular compartment. The mechanisms linking inflammation in the skin and joints and in the vascular walls are poorly understood. One hypothesis for the increase in vascular inflammation observed in patients with psoriasis involves circulating pro-inflammatory cytokines. Patients with psoriasis have an increase in serum levels of tumor necrosis factor alpha (TNF-alpha), Interleukin-17 (IL-17), IL-22, IL-6 as well as a the chemokine S100A913. It is possible that one of those cytokines/chemokine induces vascular inflammation in the vascular compartment. The purpose of this cross sectional retrospective study is to highlight the correlation between vascular wall inflammation using 18F-2-fluoro-2-deoxy-D-glucose - Positron Emission Tomography (FDG-PET) fluorodeoxyglucose technology and pro-inflammatory cytokines/chemokine.
The NeoVas Bioresorbable Coronary Scaffold Randomized Controlled Trial is a prospective, multi-center, randomized trial. The study compares NeoVas sirolimus-eluting bioresorbable coronary scaffold with XIENCE PRIME Everolimus Eluting Coronary Stent System (EECSS) to evaluate the safety and efficacy of NeoVas in the treatment of patients with de novo coronary lesion.
The NeoVas Bioresorbable Coronary Scaffold Registry Trial is a prospective, multi-center, single arm registry trial based on the NeoVas FIM study which verified the safety and effectiveness of NeoVas initially. This study is to evaluate the safety and effectiveness of NeoVas sirolimus-eluting bioresorbable coronary scaffold in the treatment of patients with de novo coronary lesion.
UCORBIO enrolls patients who undergo coronary angiography (for any indication). The investigators draw blood at the moment of insertion of the procedural arterial catheter. At the moment of inclusion indication, procedural details, risk factor status, medication use and quality of life (RAND-36 and EuroQoL) is assessed. Patients are then followed-up for the occurrence of major adverse cardiovascular events for 5 years. During the follow-up period patients receive a questionnaire every year to check for hospital admissions. The questionnaires at two and five years of follow-up are enriched with quality of life questionnaires (RAND-36 and EuroQoL).
A prospective, randomized, multicenter study in patients with an indication for coronary artery revascularisation who have been accepted for percutaneous coronary intervention (PCI) of the left main coronary artery. Patients will undergo standard PCI of the left main coronary artery and will be randomized in a 1:1 fashion to the Synergy stent or to the XIENCE stent. Dual antiplatelet therapy (DAPT) will be stopped at t=4 months in the Synergy arm whereas in the control arm DAPT will be continued for 12 months. A subgroup of 100 patients will have control angiography with Optical Coherence Tomography (OCT) at t=3 months after treatment.
Background: - This study is designed for people who need a standard, non-research invasive coronary angiogram to find out if they have heart disease. Researchers want to take a computed tomography (CT) scan of people s hearts before their procedure to see if this less invasive test can also diagnose coronary artery disease. Objectives: - To learn if a new way to view CT pictures is able to accurately diagnose coronary artery disease. Eligibility: - People age 55 and older who need a coronary angiogram. Design: - Participants will be screened with their medical records. - Participants may give a blood sample. - Participants may have a CT scan of the heart with and without contrast. The CT scan will not interfere with their medical care. - Participants blood pressure and heart rhythm will be monitored before, during, and after the CT scan. They may have an electrocardiogram. - Before the scan, participants will have an intravenous catheter put into their arm. It will be used to inject contrast. - Participants may take a beta blocker to slow their heart rate. - Participants may take nitroglycerin under their tongue. It will enlarge their heart blood vessels and improve picture quality. It may cause a flushing sensation or headache. - Participants will lie on their back on a padded table. The table slides into a large, donut-shaped machine. An x-ray tube will move around their body, taking pictures. They will be asked to hold their breath for 5 seconds at a time. - Participants will be called 30 days after their angiogram. They will answer questions about their health, hospital visits, or medical treatments.
Microvascular coronary dysfunction (MCD) (abnormities in small blood vessels/arteries in heart) with symptoms of persistent chest pain, primarily impacts women. There are an estimated 2-3 million women in the US with MCD and about 100,000 new cases annually. Recent data from our research group suggests that coronary microvascular disease impairs the way the heart relaxes. This pilot study will attempt to exacerbate this phenotype in an effort to better understand the pathophysiology of the disease. The investigators will recruit 30 volunteers total (10 healthy calibration subjects, 10 women with microvascular disease, and 10 age-match women for the group with microvascular disease). Subjects will undergo a series of "stress" maneuvers in conjunction with advanced cardiac magnetic resonance imaging.
The primary objective of the BIODEGRADE study is to evaluate clinical efficacy of the Orsiro drug-eluting stent compared with Biomatrix drug-eluting stent, both of which have biodegradable polymer for the treatment of all-comers' coronary artery diseases.
The investigators aim at evaluating the long-term (5-year) clinical outcome following Absorb BVS implantation in a real world, all-comers population of consecutive patients, as treated according to the indications, techniques and protocols used in the participating institutions.
The aim of this study is to prove that using a CytoSorb(TM) filter in the cardiopulmonary circuit attenuates the inflammatory response to extracorporeal circulation in patients undergoing cardiac surgery. The hypothesis is that removing cytokines from patients' blood by the CytoSorb device significantly improves circulation and outcome in patients undergoing on-pump cardiac surgery.
