Filter by:PEDIS Study is an observational, cross-sectional, multicenter Italian study conducted in a consecutive series of patients who refer to the Emergency Departments (either spontaneously or sent by their attending physicians) for the recent (less than one months) development of exertional dyspnea. The general aim of the study is to assess the prevalence of PE in the overall population referring to the Emergency Departments without potential explanations for dyspnea
Hospital-acquired venous thromboembolism (HA-VTE) is one of the leading preventable causes of in-hospital mortality, but prevention of VTE in hospitalized medical patients remains challenging, as preventive measures such as pharmacological thromboprophylaxis (TPX) need to be tailored to individual thrombotic risk. The broad objective of this project is to improve VTE prevention strategies in hospitalized medical patients by prospectively examining VTE risk factors (including mobility) and comparing existing risk assessment models.
Transcatheter aortic valve implantation (TAVI) is a rapidly growing treatment option for patients with aortic valve stenosis. Stroke is a feared complication of TAVI, with an incidence of around 4-5% in the first 30 days. Up to 50% of patients undergoing TAVI have an indication for oral anticoagulants (OAC) mostly for atrial fibrillation. OAC use during TAVI could increase bleeding complications, but interruption during TAVI may increase the risk for thromboembolic events (i.e. stroke, systemic embolism, myocardial infarction). Recent observational data suggest that periprocedural continuation of OAC is safe and might decrease the risk of stroke. Beside the potential reduction of thromboembolic events, continuation of OAC is associated with an evident clinical ancillary benefit for patients and staff. Since periprocedural OAC interruption not infrequently leads to misunderstanding and potentially dangerous situations, when patients are not properly informed before hospital admission or may experience difficulties with the interruption regimen. Hypothesis: Periprocedural continuation of oral anticoagulants is safe and might decrease thromboembolic complications without an increase in bleeding complications at 30 days
Multicentric case-control study that is aims at: - evaluating the prevalence of pulmonary embolism among a large population of consecutive patients admitted for COVID-19 pneumonia into two large university hospitals in Paris, France: Groupe Hospitalier Paris Saint-Joseph (GHPSJ) and Hôpital Européen Georges Pompidou (HEGP) - and identifying the characteristics associated with pulmonary embolism by using a nested case control study design within the patients who underwent either unenhanced computed tomograpghy (CT) or CT pulmonary angiogram (CTPA) evaluation.
To estimate the risks of daily hospital admissions for pulmonary embolism associated with short term exposure to climatic factors (temperature, precipitation, air pressure, sunshine duration, relative humidity, wind speed, and ambient fine particulate matter [aerodynamic diameter ≤2.5 μm; PM2.5]) in China.
Venous thromboembolic disease is a significant cause of morbidity and mortality. The purpose of the RAPID registry is to collect information on the Angiovac procedure and Angiovac device used in the treatment of deep venous thrombosis (DVT), right heart pathology and 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.
To evaluate by intravascular OCT study the presence of microvascular pulmonary thrombosis in patients with COVID-19, high D-dimer levels and contrast CT scan negative for pulmonary thrombosis. We'll also evaluate the extension of microvascular pulmonary thrombosis in patients with contrast CT scan positive for pulmonary embolism in areas where contrast CT scan was negative.
The purpose of this prospective randomized controlled study is to evaluate the risk of asymptomatic cerebral embolism during catheter ablation of atrial fibrillation (AF) with AI-HPSD strategy versus standard radiofrequency ablation settings, with the diagnosis of asymptomatic cerebral embolism is determined by brain high-resolution diffusion-weighted magnetic resonance imaging technique.
Patients with renal carcinoma was reported at high incidence of perioperative pulmonary embolism from current study. The investigators aimed to determine the incidence and outcome of this group of patient in the tertiary-care, university hospital and the rate of intraoperative transesophageal echocardiography utility and outcome.
