Active clinical trials for "Pulmonary Embolism"

Background. Management of patients with suspected Pulmonary Embolism (PE) is problematic if diagnostic imaging is not available. Pretest Clinical Probability (PCP) and D-dimer (D-d) assessment were shown to be useful to identify those high risk patients for whom empirical, protective anticoagulation is indicated. To evaluate whether PCP and D-d assessment, together with the use of low molecular weight heparins (LMWHs), allow objective appraisal of PE to be deferred for up to 72 hours, we planned to prospectively evaluate consecutive patients with suspected PE. Methods. In case of deferment of diagnostic imaging for PE, patients identified at high-risk (those with high PCP or moderate PCP and positive D-d), receive a protective full-dose treatment of LMWH; the remaining patients will be discharged without anticoagulant. All patients will be scheduled to undergo objective tests for PE within 72 hours. Standard antithrombotic therapy will be then administered when diagnostic tests confirmed Venous ThromboEmbolism (VTE).

The investigators' aim in this study is to assess the sensitivity and accuracy of YEARS algorithm in the diagnosis of PE.

The patients presenting with acute pulmonary embolism and right ventricular dysfunction are at high risk for life-threatening events and must be identified in the emergency department for adequate care and hospital admission. Echocardiography can identify right ventricular dysfunction, but this test is not always available, and echocardiographic criteria of right ventricular dysfunction vary among published studies. The primary purpose of this protocol is to study the prognostic value of a cardiac biomarker, h-FABP (heart-type Fatty Acid-Binding Protein) , to identify in the emergency department the patients presenting with high risk pulmonary embolism. As secondary outcomes, H-FABP results will be compared to other cardiac biomarkers (BNP, troponin) and clinical score performances that have been previously studied to stratify the prognosis of patients with pulmonary embolism in the emergency department.

The SENTRY Bioconvertible Inferior Vena Cava (IVC) Filter has been developed to provide temporary protection against pulmonary embolism (PE).

The purpose of this study is to determine whether systematically performing computed tomography (CT) venography (i.e a CT acquisition of the pelvis and of the lower limbs, during the venous phase of opacification) in addition to thoracic CT angiography in women with suspected postpartum pulmonary embolism (PE) results in a gain in venous thromboembolism detection rate.

In a randomized controlled design the study aims to investigate whether an intervention of 8 weeks supervised bicycle training program in addition to usual care can positively influence the physical capacity and quality of life in patients medically treated for pulmonary embolism.

A blood sample was taken before starting the patients on any thrombolytic treatment. The positivity threshold for D-Dimer was above 250 ng/ml. CTPA was performed after performing blood sampling. Patients with confirmed pulmonary embolisms were admitted to ICU for continued monitoring of vitals, consciousness level, and signs of tissue perfusion. Signs of shock or hemodynamic instability should be observed regularly. Patients were managed in the ICU with anticoagulants by parenteral use. The most commonly used items were Heparin, either Unfractionated (UFH) or low-molecular-weight heparin (LMWH).D-dimer levels can leverage to detect PE. D-dimer levels can help in guiding the option of CTPA and the initiation of treatment for patients with suspected PE.

Objective: To evaluate whether trimester specific d-dimer levels and brain natriuretic protein (BNP), along with the modified Wells score (MWS), is a useful risk stratification tool to exclude pregnant women at low-risk of pulmonary embolism (PE) from diagnostic imaging with radiation exposure.

Caribbean Hispanics are a population with a disproportionately high prevalence of cardio-metabolic disorders but with a limited expectation of benefits from current pharmacogenetic algorithms derived mainly in subjects of relatively pure ancestry. The investigators focus on warfarin responses to develop urgently-needed DNA-driven prescription guidelines for this population, who have arisen from European, West African and Amerindian genomic origins to produce a highly heterogeneous population. Our project combines admixture analysis and DNA-sequencing with development of more accurate rules for better predictability of warfarin dosing to immediately serve this medically underserved population.

PRESERVE is a multi-center, prospective, open-label, non-randomized investigation of commercially available IVC filters from 6 manufacturers placed in subjects for the prevention of pulmonary embolism (PE). This study will enroll up to 1,800 IVC filter subjects (with a maximum of 300 subjects per IVC filter brand) at up to 60 sites in the US. The primary objective of this investigational device exemption (IDE) clinical investigation is to evaluate the safety and effectiveness of the commercially available IVC filters (retrievable and permanent) in subjects with clinical need for mechanical prophylaxis of PE with an IVC filter.
