Active clinical trials for "Vascular Diseases"

It's a phase III, prospective, multicenter, randomized controlled trial to evaluate the safety and efficacy of the pulmonary artery denervation (PADN) for heart failure (HF) patients diagnosed with pulmonary hypertension associate with left heart disease (PH-LHD) by right heart catheterization.

The goal of this clinical trial is to determine whether an upfront invasive strategy of TEVAR plus medical therapy reduces the occurrence of a composite endpoint of all-cause death or major aortic complications compared to an upfront conservative strategy of medical therapy with surveillance for deterioration in patients with uncomplicated type B aortic dissection.

An observational cohort study of the frailty of vascular surgery patients undergoing intervention and their outcomes.

Background: Some genetic diseases put increase the risk of heart and blood diseases, which are the number one cause of death and disability in the U.S. Researchers want to study diseases of the heart and/or blood vessels. They want to collect data and specimens from affected people, their family members, and healthy people. Objective: To study diseases of the heart and/or blood vessels. Eligibility: People age 2 and older who may have genetic disease affecting the heart and/or blood vessels Their relatives Healthy volunteers Design: Participants will be screened with a medical history, physical exams, and imaging tests. Participants may have a few visits or visits for 2 weeks or more. This will depend on their age and disease status. Visits may include: Photographs of the face and body Heart tests Samples taken of blood, urine, saliva, skin, and/or tissue Scans. For some, a dye may be injected into a vein. A six-minute walk test Lung tests. For some, participants will blow into a tube. For others, they will breathe in a gas from a mask, have a small injection, then have a scan. Stress tests while walking on a treadmill or riding a stationary bike Ultrasound of veins and arteries Devices outside the body testing the stiffness and function of arteries Eye exam and eye tests. For some, a dye may be injected in a vein. Blood pressure tests Measurements of blood flow under the skin and in the arms and fingernail blood vessels Devices outside the body testing flexibility of the blood vessels and skin, and skin temperature

Spontaneous coronary artery dissection (SCAD) is a cause of acute coronary syndrome (ACS). Most patients are treated with beta-blockers (BB) and antiplatelet drugs (AP) on empiric basis. The Beta-Blockers and Antiplatelet Agents in Patients with Spontaneous Coronary Artery Dissection (BA-SCAD) randomized clinical trial is an academic, pragmatic, nation-wide, prospective study developed under the auspices of the Spanish Society of Cardiology (SEC) that aims to assess the efficacy of medical therapy in SCAD patients. Using a factorial 2x2 design, patients will be randomized (1:1/1:1) to: 1) BB (yes/no) and 2) short AP regimen (1 month) vs prolonged dual AP therapy (DAPT) (12 months).Only patients with preserved left ventricular ejection fraction (LVEF) will be randomized to BB (yes/no) because patients with LVEF <40% will receive BB according to current guidelines. Likewise, only medically managed patients will be randomized to short AP therapy vs 1-year DAPT. The study will have a pragmatic, open label, blind outcomes design (PROBE). A total of 600 SCAD patients will be randomized within 2 years (300 per arm in a factorial 2x2 design). The primary efficacy endpoint will include the composite of death, acute myocardial infarction (MI), stroke, coronary revascularization, recurrent SCAD, and unplanned hospitalization for ACS or heart failure at 1 year. The primary safety endpoint will be bleeding. All patients will be clinically followed yearly. The main study will be pragmatic but a comprehensive set of additional studies (clinical, imaging, biomarkers, inflammatory, immunologic, pharmacogenetic and genetic) will be organized to ensure an holistic view on this challenging condition.

The first Intestinal Vascular Emergency Unit (SURVI), with the institutional support of AP-HP, opened on 4 January 2016, within the Paris-Nord Val de Seine University Hospital Group. This intensive care is dedicated to the management of mesenteric ischemias (acute mesenteric ischemias, chronic mesenteric ischemias) and Intestinal Vascular Diseases Without Ischemia. The organisation of this type of dedicated centre, combining advances in resuscitation, interventional radiology and knowledge of intestinal vascular diseases, has led to a radical change in the prognosis for acute mesenteric ischaemia with a survival rate of over 80% and an intestinal resection rate of less than 40%. Acute mesenteric ischaemia (AMI) is characterised by the combination of digestive distress and vascular insufficiency: occlusive (thrombosis, embolism, arterial, venous) or non-occlusive (low flow or vasospasm). The vital prognosis is catastrophic in the absence of treatment (the mortality rate of an intestinal infarction is almost 100% without treatment), and the functional and anatomical after-effects are major for the survivors. Many intestinal vascular diseases have been identified as providing acute and chronic mesenteric ischaemia. The nosological framework of these diseases is broad, ranging from constitutional diseases of the vessels (collagenosis, arcuate ligament syndrome) to acquired diseases of a thrombophilic, cardiac, degenerative, autoimmune, iatrogenic, traumatic nature... The rarity of these diseases (with the exception of atherosclerotic disease, the incidence of which is increasing with the ageing of the population) makes their level of knowledge insufficient. The natural history of vascular diseases without ischaemia (rate of acute and chronic mesenteric ischaemia, mortality rate, resection rate...) is currently not described. The construction of a longitudinal observational cohort is necessary for the prevalence of ischaemic complications and predictive factors.

Voed je Beter is a randomized, multicenter, controlled trial to examine whether personalized guidance to increase adherence to the Dutch dietary guidelines, compared to usual care, improves health of cardiovascular patients who receive regular medical treatment.

Spontaneous coronary artery dissection (SCAD), is an underdiagnosed pathology, affecting predominantly young women without traditional cardiovascular risk factors and is associated with major adverse outcomes including myocardial infarction, cardiac arrest, or death. Timely diagnosis of SCAD as well as clinical follow-up are of the essence in this pathology associated with major cardiac adverse outcomes. Despite recent improvements in diagnosis and recognition of the importance of SCAD, it remains poorly studied and understood. In this context, we designed the SwissSCAD registry, a large, observational, prospective, cohort study, to describe the natural history of SCAD, its outcomes and its treatments.

The ability to have a visual aid to depict areas of vascular disease that are affecting the patient's health can help in patient comprehension of the problem. This comprehension can lead to better understanding of the issue and increase patient compliance to treatment. The hand drawn sketch produced by the ultrasound technologist provides an inadequate visualization of the vascular insufficiency that is causing the patient's symptoms. PIUR imaging has developed PIUR Infinity tUS, a 3D freehand tomographic ultrasound system capable of rapid, safe and accurate reconstructive 3D quantifiable vascular imaging. This system will provide a low cost and reproducible imaging solution that will be an effective educational tool for people with vascular disease.

DCB can maximize the patency rate of blood vessels on the basis of intraluminal DA. DA+DCB treatment is effective and safe [8], and the advantages of DA and DCB in the treatment of severe calcification and occlusive disease across joints and lower extremities have been confirmed. The combined application of DA and DCB in the treatment of peripheral arterial disease has a good early and mid-term effect. Konstantinos et al. reported that DARRT has a higher first-phase patency rate compared with DCB. A retrospective study by Sebastian et al. showed that compared with PTA after DA, the combination of DA and DCB has a better event-free survival rate after 12 months of follow-up. Therefore, DA combined with DCB therapy may be one of the best and most promising methods for the treatment of lower extremity ASO.
