Filter by:Venous thromboembolism (VTE), clinically presenting as deep vein thrombosis or pulmonary embolism (PE) is the third most common cardiovascular disease and is associated with substantial short- and long-term morbidity and mortality and high costs of care. In addition negative physical and mental complications following VTE are common. However in terms of PE, there are no structured follow-up programs in Denmark and there is considerable variation in practice patterns of post-PE management both within and between countries. The Attend-PE project aims to develop, test and implement a structured follow-up model in a hospital setting for patients with pulmonary embolism. The Attend-PE is a pre-post intervention study and will estimate the effectiveness of implementing the structured care model on a national level.
This multicenter international prospective cohort study will include patients with AIS with a known or newly diagnosed anticoagulant-naïve AF. All centers will use the same transcranial Doppler machine for one-hour monitoring with bilateral 2-MHz probes within 24 hours of symptom onset. Recordings will be analyzed for MES by a blinded central reader. The primary aim is to determine the proportion of patients with MES and the association of MES with functional outcomes assessed by a modified Rankin scale (mRS) score at 90 days.
The occurrence and progression of lung cancer is related to visceral adipose tissue (VAT). Epicardial adipose tissue (EAT) is a kind of VAT, producing a variety of inflammatory cytokines and adipokines, participating in the formation of local inflammation, promoting the formation of pre-thrombotic state, and leading to the occurrence of thromboembolism. Patients with lung cancer have increased inflammatory response and are more prone to suffer thrombosis. However, in lung cancer patients, the clinical correlation between EAT and pulmonary embolism has not been reported. Objective: To analyze the risk factors of poor prognosis in lung cancer patients with PE, and to explore the predictive value of EAT in pulmonary embolism events and death in lung cancer patients. Methods: EAT volume and density, as well as anthropometric and blood biomarkers, were evaluated in a sample of lung cancer patients, half with pulmonary embolism and half without. The incidence of adverse prognosis and related factors were followed up by telephone.
The increased use of diagnostic imaging and especially computed tomography pulmonary angiography in patients suspected of pulmonary embolism (PE) is an important point of concerns. The goal of this pragmatic cluster-randomized trial is to compare the diagnostic strategy based on the four-level pulmonary embolism probability score (4PEPS) and current practices. The main questions it aims to answer is: "Does the diagnostic strategy based on 4PEPS significantly reduce the use of thoracic imaging without increasing the risk of serious adverse events as compared to current diagnostic practices?" Patients suspected of having PE in the participating emergency departments will be included and followed for 90 days. In ten centers, the emergency physicians will apply the 4PEPS strategy and in ten other centers, the emergency physicians will be free to do as they see fit. Researchers will compare the two groups of patients to see if the rate of diagnostic thoracic imaging tests and the rate of adverse events related to diagnostic strategies will differ.
To evaluate treatment outcomes of patients diagnosed with pulmonary embolism.
LAAOS-4 aims to determine if catheter-based endovascular left atrial appendage occlusion prevents ischemic stroke or systemic embolism in participants with atrial fibrillation, who remain at high risk of stroke, despite receiving ongoing treatment with oral anticoagulation.
About half of patients who suffer of a pulmonary embolism (blood clots in the lungs), do not clear completely the clots overtime, increasing the risk of having a new blood clot in the lungs and elevated blood pressure in the pulmonary artery; therefore, developing fatigue, shortness of breath, and heart failure. The objective of this clinical trial is to compare 3 months of daily Macitentan (a medicine to increase the diameter of the pulmonary artery) in addition to blood thinners vs. blood thinners alone in patients with acute blood clots in the pulmonary artery: Question 1: Whether the use of Macitentan in addition to blood thinners enhances the process of cleaning the blood clot in the pulmonary artery compared to blood thinners alone. Question 2: Whether the use of Macitentan in addition to blood thinners is associated to improve the fatigue and shortness of breath in patients after a pulmonary embolism compared to blood thinners alone. Participants will be asked to take a capsule for 3 months in addition to blood thinners. The capsule could contain either Macitentan (medicine) or a placebo (not medicine). In 3 months, participants will have a new image of the pulmonary artery to document the cleaning of the clots. Also, blood and urine samples will be collected, as well as a questionnaire will be filled out. In 6 months, patients will have repeated images of the heart as well as repeated questionnaires.
Evaluate the safety and efficacy of the Aventus Thrombectomy System for aspiration thrombectomy in subjects with acute pulmonary embolism.
A study of how supplemental oxygen helps patients with acute pulmonary embolism (PE). Hypothesis: Oxygen affects right ventricular dysfunction (RVD) in patients with acute pulmonary embolism (PE) primarily by relieving hypoxic pulmonary vasoconstriction and reducing pulmonary pressure (PA) pressure, and that this process is metabolically driven.
This prospective, observational, post-market study will be performed to collect patient-level data on the Celect Platinum Vena Cava Filter Sets and the Günther Tulip Vena Cava Filter Retrieval Set to confirm continued safety and performance of the devices throughout their expected lifetime and continued acceptability of the benefit:risk ratio. Additionally, the study intends to evaluate longer-term (i.e., up to 5 years) outcome data while the filter is indwelling.
