Active clinical trials for "Pulmonary Embolism"

It is known that patients who fracture their legs sometimes develop blood clots (known as deep vein thrombosis) in their legs. These clots may cause pain and swelling in the leg or they may detach and travel to the lungs producing shortness of breath, chest pain, and sometimes death. Unfortunately, it is not known how frequently these complications occur after leg fractures, or if the use of a blood thinner medication can effectively and safely prevent these clots. Doctors at hospitals across Canada are conducting a study in which patients who have surgery for leg fractures receive either a once-daily injection of a blood thinner, known as low molecular weight heparin, or a placebo injection for up to 14 days after their fractures. Neither the patients nor the doctors know which patient is on the medication and which patient is on placebo. All patients receive an ultrasound examination of their legs at 2 weeks after surgery to monitor for deep vein thrombosis. In addition, all patients are checked for symptoms of leg or lung clots and any side effects of the medication for 3 months. If the blood thinner is shown to be effective at reducing this complication and documented to be safe and cost-effective in this setting it will be recommended for use in such patients. If, on the other hand, the frequency of deep vein thrombosis is too low to justify the cost or inconvenience of taking this medication, this will also be an important finding.

Patients with newly diagnosed pulmonary embolism and high thromboembolic risk will be randomized to screening for atrial fibrillation or standard of care using intermittent ECG registration for at least two weeks.

Fibrinolysis is the body's process that prevents blood clots. The investigators hypothesize that patients presenting with acute pulmonary embolism (PE) or blood clots in the lungs differ in their fibrinolytic deficit phenotype. The investigators aim to use biomarkers directly involved in endogenous fibrinolytic cascade including PAI-1, Alpha-2-Antiplasmin (A2A), TAFI, D-dimer, and Fibrinogen to phenotypically characterize patients presenting with acute PE and to correlate these biomarkers with clinical, echocardiographic, computed tomography (CT), and functional status outcomes.

Acute Pulmonary Embolism (PE) is the most serious clinical presentation of venous thromboembolism (VTE), a leading cause of cardiovascular mortality, exceeded only by stroke and myocardial infarction. Chronic thromboembolic pulmonary hypertension (CTEPH) is the most severe chronic form of CTED and it occurs in 2-4% of patients after acute PE. In Portugal little is known about PE epidemiology and its outcomes, including complications like CTED. The main goal of this study is, therefore, to understand PE epidemiology and complications in the northern region of Portugal. This information can enable the organization of a structured health care network that can potentially benefit all PE patients.

Forward-looking troop established(constituted) by the patients having been included in the study " PADIS EP ", PHRC on 2006 and 2009, randomized checked(controlled), double-blind, comparing an anticoagulating treatment(processing) extended by coumadine versus placebo during 18 months at patients having had a first episode of EP idiopathique treated(handled) initially 6 months by anti-vitamin K.

The LDS may contain information of significant diagnostic and physiological value regarding the pulmonary parenchyma and vasculature, as well as the cardio- vascular system in general. In pilot clinical studies of patients with acute decompensated heart failure (ADHF) as well as patients with Pulmonary Hypertension, LDS signals patterns unique to these conditions were identified. We believe that these newly discovered ultrasound signals might provide a non-invasive radiation-free means to diagnose and monitor patients with Pulmonary Embolism. The purpose of this study is to assess the utility of noninvasive assessment of lung Doppler signals performed via transthoracic parametric Doppler. The objective of the study is to evaluate the lung Doppler signals (LDS) in patients diagnosed with acute PE, in order to determine the potential assessment value of this non-invasive method in this potentially life threatening condition.

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.

This study evaluates whether treatment with rosuvastatin on top of standard anti-coagulant treatment will decrease the risk of recurrent venous thromboembolism and arterial thromboembolic events in patients with previous deep vein thrombosis or pulmonary embolism.

To evaluate the clinical characteristics, risk factors, management and outcome of patients admitted e acute pulmonary embolism in chest diseases department and Respiratory Icu in Assiut University hospital

To simplify and improve the diagnostic approach to patients with clinically suspected recurrent DVT by determining whether the results of the combination of IPG and d-dimer testing, using a whole blood agglutination assay, can be used in the management of such patients.
