Early Systolic Notching in Pulmonary Embolism

Pulmonary Embolism

Venous thromboembolism (VTE), clinically seen as deep vein thrombosis (DVT) or pulmonary embolism (PE), is the third most common acute cardiovascular syndrome after myocardial infarction and stroke. In a study conducted by critical care and emergency physicians, lung ultrasonography (US) for pleural infarction areas, lower extremity venous US in terms of DVT, and focused cardiac US in terms of right ventricular strain were demonstrated with different diagnostic values for PE. However, no ultrasonographic method alone has a high diagnostic value for PE alone in the literature. In a recent study, it is stated that a new cardiac finding (early systolic notch- ESN) has high sensitivity (92%) and specificity (99%) in massive and submassive emboli. However, the limited patient population and the exclusion of many patient groups limits the applicability of the study and its use in other patient groups. With this study, it was aimed to determine the diagnostic value of ESN finding within the emergency department conditions by keeping the patient population wider.

Venous Thromboembolism; Deep Vein Thrombosis; Pulmonary Embolism; Anticoagulants

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.

Optimizing Protocols for the Individual Patient in CT Pulmonary Angiography.

Pulmonary Embolism

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.

Pharmacoepidemiology Treatment of Symptomatic Pulmonary Embolism in Hospitalized Patients Aged 75...

ElderlyPulmonary Embolism1 more

The treatment of the venous thromboembolic disease, including pulmonary embolism (PE), is based on anticoagulants. During the last decade, all the randomized clinical trials evaluating these anticoagulants have included PE patients with an average age below 60 years. But in clinical pratice, approximately 50% of PE patients are older than 75 years. So the investigators want to perform a french multicentre prospective cohort of consecutive patients receiving an anticoagulant treatment for a symptomatic and confirmed PE. All the validated and available anticoagulant treatments are authorized in this cohort (unfractionnated and low molecular weight heparins, fondaparinux, vitamin K antagonists and direct oral anticoagulants). This cohort will provide data regarding the bleeding risk and the risk of PE recurrences and regarding the pharmacokinetic (PK) and pharmacodynamic (PD) properties of these anticoagulants in this older population. Using population approach modelling , the investigators will pay particular attention to the sources of PK/PD variability PK / PD such as genetic polymorphisms of P-glycoprotein and cytochrome P450. Using all these data , the investigators will try to identify significant risk factors for bleeding and venous thromboembolic events.
