Active clinical trials for "Pulmonary Embolism"

In this study the investigators will evaluate whether more careful reading (than the current standard) of routine computerised tomography pulmonary angiography (CTPA) performed in the clinical work-up of suspected (pulmonary embolism (PE) will differentiate patients with acute PE from those with more chronic or acute on chronic PE, which could be indicative of the presence of chronic thromboembolic pulmonary hypertension (CTEPH)"

The aim of this work is to emphasize the role of non-contrast MR imaging in diagnosis of acute pulmonary embolism in comparison to CTA and contrast enhanced MRA as gold standard techniques.

Little is known about the current management status of venous thromboembolism (VTE) in Southwestern China. We aimed to investigate the status of anticoagulant administration in VTE in Southwestern China and assess the potential predictors of deep vein thrombosis (DVT) complicated pulmonary embolism (PE). We extracted data from YiduCloud database from December 2006 to November 2018 and performed a cross-sectional survey of VTE. The demographics, laboratory tests, and anticoagulants were collected and analyzed in the logistic regression model, classification tree and Random Forest model.

The scope of this study is the external validation of an explainable deep learning-based classifier for the diagnosis and detection of pulmonary embolism in computed tomography pulmonary angiography (CTPA) and contrast enhanced CT scans.

To explore the pathogenesis, therapy and outcome of pulmonary embolism (PE) and chronic thromboembolic pulmonary hypertension (CTEPH).

Retrospectively analyze the risk factors of VTE in 5774 patients with thoracic trauma from 33 hospitals in China, and established a risk prediction model

The primary objective of this study is to evaluate the practice patterns of rivaroxaban usage invenous-thromboembolism (VTE) and non-valvular atrial fibrillation (NVAF) in cancer patients. The secondary objectives are to evaluate outcomes such as recurrent VTE, stroke and bleeding for cancer patients on rivaroxaban.

The purpose of the study is to evaluate the performances of Soluble Fibrin assay for exclusion of Pulmonary Embolism and Deep Venous Thrombosis. Secondary objectives are to determine the threshold value from the ROC curves, the possible interest in the positive diagnosis of Venous Thromboembolism (VTE), and to verify the absence of influence of age on the SF results.

Computed tomographic pulmonary angiography (CTPA) is considered the gold standard for the diagnosis of pulmonary embolism (PE). PE is a potentially fatal disease in which a thrombus is lodged into a pulmonary artery blocking blood flow and potentially leading to respiratory distress, acute right cardiac failure or death. Therefore early and correct diagnosis is crucial. The diagnostic and clinical value of CTPA has already been firmly substantiated. Unfortunately up to 7.3% of PE scans are still deemed to be non-diagnostic, for example due to insufficient contrast enhancement in the target arteries. Therefore future research should focus on two important aspects of CT imaging. On the one hand optimal enhancement for the individual patient, on the other hand preventing additional risk of CT imaging - namely contrast induced nephropathy (CIN) and radiation risk. Thus the purpose of our study will be to optimize radiation dose settings (e.g. tube voltage, tube current) and CM application for the individual patient in CTPA.

The purpose of the study is to evaluate the performances of Soluble Fibrin for diagnosing Pulmonary Embolism. Secondary objective is to compare the diagnostic performances of the Soluble Fibrin Assay and the D-Dimer test.
