Filter by: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.
The purpose of this study is to analyze the clinical manifestations, imaging features, and prognosis-related factors of pulmonary embolism, and to explore the prognosis risk assessment model for Chinese patients
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.
The purpose of this study is to investigate the prevalence of venous thromboembolism in a regional health care system (Region Östergötland, Sweden) before and during the SARS-COV-2 pandemic. In a retrospective observational study, we will review patient data, diagnostic data and treatment data over a three-month period since the onset of the SARS-COV-2 pandemic. This data will be compared with data from the corresponding time frame during the years 2015 to 2019.
The OVID study will show whether prophylactic-dose enoxaparin improves survival and reduces unplanned hospitalizations in ambulatory patients aged 50 or older diagnosed with COVID-19, a novel viral disease characterized by severe systemic, pulmonary, and vessel inflammation and coagulation activation.
To improve the safety of diagnosis and therapy for a set of conditions and undifferentiated symptoms for hospitalized patients, the investigators will employ a set of methods and tools from the disciplines of systems engineering, human factors, quality improvement,and data analytics to thoroughly analyze the problem, design and develop potential solutions that leverage existing current technological infrastructure, and implement and evaluate the final interventions. The investigators will engage the interdisciplinary care team and patient (or their caregivers) to ensure treatment trajectories match the anticipated course for working diagnoses (or symptoms), and whether they are in line with patient and clinician expectations. The investigators will use an Interrupted time series (ITS) design to assess impact on diagnostic errors that lead to patient harm. The investigators will perform quantitative and qualitative evaluations using implementation science principles to understand if the interventions worked, and why or why not.
