Filter by:The goal of this initial proof of principle single arm cohort trial is to determine if contemporary endovascular venous intervention, compared with a 1:1 propensity-matched medical therapy arm of the ATTRACT trial, significantly reduces the 2-year occurrence of Post Thrombotic Syndrome (PTS) in subjects with symptomatic proximal Deep Vein Thrombosis (DVT).
The objective of the "anticoagchoice" study is to analyze the preferences of people suffering from phlebitis, in terms of anticoagulant, to improve adherence to these treatments, to adapt the medical prescriptions.
Ongoing registration of patients with venous thromboembolism treated by means of antithrombotic therapy, thrombolisys, open surgery, endovenous desobstruction and stenting.
The objective of this research study is to test the accuracy of preexisting criteria versus expert interpretation for the diagnosis of acute coronary occlusion (major heart attack due to a completely blocked blood vessel). If our hypothesis proves to be true, this would provide a significant improvement in the care for patients who present to the hospital with possible symptoms of coronary ischemia (symptoms due to lack of blood flow to the heart). The primary analysis will be designed as a multi-center, retrospective case-control study.
Epidemiological, observational, non-interventional, multicentric study on patients diagnosed with cancer who develop a venous or arterial thromboembolic episode, symptomatic or incidental, within a month prior to cancer diagnosis or at anytime after such diagnosis
A prospective, multicentric cohort study including 166 patients with symptomatic aortic stenosis treated with transcatheter aortic valve implantation (TAVI). - The main objective is to determine whether the high residual platelet reactivity rates in patients undergoing TAVI is associated with the occurrence of clinical and / or subclinical prosthetic valve thrombosis measured by echocardiography and multi-slice computerized tomography
Non-valvular (NV) atrial fibrillation (AF) increases the risk of stroke by approximately fivefold. The atrial thrombi associated with AF are seen within the left atrial appendage (LAA) in most cases (> 90%). Anticoagulation with a vitamin-K antagonist (VKA) is recommended to prevent thromboembolic complications and to resolve thrombi. Non-VKA oral anticoagulants (NOACs) have replaced the VKA for the thromboprophylaxis in patients with NVAF since 2010. Therefore, NOAC can be the excellent alternative to VKA concerning resolving preexisting LAA thrombi because of its rapid onset of action and no need of bridging with heparin. However, there is still lack of data regarding the optimal treatment for patients with AF and thrombi in LAA with NOAC. There are only several case reports of the efficacy of NOACs in resolving LAA thrombi available. Edoxaban, which has data showing efficacy and safety in thromboprophylaxis, can be the new option for treatment of patients with AF and LAA thrombi. The purpose of this study is to evaluate the efficacy of Edoxaban in resolving the LAA thrombi, which is related with nonvalvular AF.
As of today, no suitable multiparametric predictive method is available to properly estimate stroke risk in patients with carotid artery stenosis. Carotid artery stenosis is one of the proven risk factors of stroke incidence, but the indication of its intervention is merely the grade of stenosis itself. The current international guidelines suggest intervention for asymptomatic patients only with potentially high risk plaques but pharmacological treatment is advised to low risk patients. Unfortunately there is no proven and widely accepted system to distinguish these two categories of patients with carotid artery stenosis. In this project the following parameters will be assessed both in asymptomatic and symptomatic patients: 1, preoperative stroke risk prediction based on comparative analysis of CT angiography (CTA) results of plaque morphology and ultrasound (US) based plaque elastography analysis, 2) intracranial bloodflow will be measured by transcranial Doppler sonography(TCD), 3) presence recent of silent brain ischemia on diffusion weighted imaging (DWI) MR (magnetic resonance), 4) retinal perfusion measurement by optical coherence tomography angiography (OCT). The investigators aim to establish a clinically meaningful and more accurate (than stenosis grade) stroke risk prediction algorithm for asymptomatic carotid stenosis patients based on these parameters.
The purpose of the study is to evaluate a new radiotracer called 64Cu-FBP8 for PET-MR imaging of thrombosis. The tracer has the potential of detecting thrombosis anywhere in the body, for instance in the left atrial appendage of patients with atrial fibrillation, and thereby may provide a non-invasive alternative to the current standard-of-care methods.
Granulomatosis with polyangiitis (GPA) is one of antineutrophil cytoplasmic autoantibody (ANCA) - associated vasculitis. Inflammation-induced thrombosis is considered to be a feature of systemic autoimmune diseases. GPA usually involves the upper and lower respiratory tract and renal systems, where necrotizing glomerulonephritis and pulmonary capillaritis are often detected. However, it may also affect other organ systems. Cardiac involvement in GPA occurs in approximately 6% to 44% of cases and is secondary to necrotizing vasculitis with granulomatous infiltrates. Cardiac involvement is an independent predictor of mortality in GPA patients. In this prospective cohort study, consecutive GPA patients who were hospitalized in the Department of Family Medicine, Internal and Metabolic Diseases at the Medical University of Warsaw in Poland are included. In all patients echocardiography and laboratory tests are perform.
