Filter by:The Investigator postulate that the use of PESI in addition to routine clinical practice, as opposed to routine clinical practice based on clinical judgment alone, will help physicians to correctly identify PE patients at low-risk of adverse outcomes. Considered that low-risk patients could benefit from a short hospital stay, aim of this study is to demonstrate that the use of PESI will lead physicians to discharge these patients earlier, thus reducing the duration of hospital stay of PE patients (primary outcome). Outpatients diagnosed with PE at the emergency department (ED) and admitted to participating units represent the target population As the availability of DOACs may influence the duration of hospital stay, the secondary objectives of the present study are: 1. to demonstrate that a shorter hospital stay for low-risk PE patients (independently on the method used to identify them) will reduce the incidence of hospital-associated complications and improve patients satisfaction and quality of life, without increasing the incidence of PE-related complications 2. to demonstrate that the use of PESI, as opposed to clinical judgment alone, will be associated with a greater proportion of patients discharged early (< 72 hours from ED admission) or treated entirely at home (< 24 hours from ED admission). 3. to demonstrate that the use of DOACs will reduce the duration of hospital stay of PE patients 4. to demonstrate that the use of DOACs, as opposed to standard treatment, will be associated with a greater proportion of patients discharged early (< 72 hours from ED admission) or treated entirely at home (< 24 hours from ED admission).
A risk stratification in hemodynamically stable patients with acute pulmonary embolism (PE) is deemed necessary to guide patient management. With the aim to improve the positive predictive value (PPV) for PE-related adverse events in in normotensive patients, a number of scores combining multiple risk-factors have been published. In addition, an algorithm for the risk-stratification of patients with PE has been proposed by the European society of cardiology. None but one of these scores underwent external and prospective validation. The aim of this study is to externally and prospectively validate the PPV for PE-related adverse events of the Bova score and modified FAST score in a large multicenter cohort.
The LDS may contain information of significant diagnostic and physiological value regarding the pulmonary parenchyma and vasculature, as well as the cardio- vascular system in general. In pilot clinical studies of patients with acute decompensated heart failure (ADHF) as well as patients with Pulmonary Hypertension, LDS signals patterns unique to these conditions were identified. We believe that these newly discovered ultrasound signals might provide a non-invasive radiation-free means to diagnose and monitor patients with Pulmonary Embolism. The purpose of this study is to assess the utility of noninvasive assessment of lung Doppler signals performed via transthoracic parametric Doppler. The objective of the study is to evaluate the lung Doppler signals (LDS) in patients diagnosed with acute PE, in order to determine the potential assessment value of this non-invasive method in this potentially life threatening condition.
To investigate the incidence of pre- and early postoperative deep venous thrombosis in patients undergoing hepatobiliopancreatic surgery, as well as potential corresponding risk factors with special attention to circulating tumor cells.
The primary objective of this study is to investigate the impact of continuous renal replacement therapy and intermittent renal replacement therapy on microbubble / cerebral microemboli generation in a cohort of critically ill patients with dialysis-dependent acute kidney injury.
This study aims at evaluating clincal practice regarding prevention of arterial and venous thrombosis following ovarian stimulation. Secondary outcomes are : 1) to describe the incidence and risk factors of arterial and venous thrombosis in women undergoing assisted reproductive technology and 2)to identify the incidence and risk factors for ovarian hyperstimulation syndrome in these women
This prospective, multicenter, multinational, phase IV, interventional single-armed (management) trial will focus on the safety, efficacy and cost-effectiveness of a new oral anticoagulant in the treatment of patients with acute intermediate-risk PE based on validated imaging (echocardiographic or CT angiographic) and laboratory biomarker (circulating levels of cardiac troponins and natriuretic peptides) parameters and their combinations.
The trial is an open-label, randomized, trial examining novel biomarkers of thrombosis in patients managed with rivaroxaban vs. standard care following treatment of pulmonary embolism (PE) with catheter-guided alteplase. Patients >18 years old who present with PE and are managed with catheter-guided alteplase will be screened for study inclusion. Patient's meeting inclusion/exclusion criteria will undergo informed consent. Immediately following completion of alteplase infusion, patients will be randomized to receipt of rivaroxaban 15 mg oral bid for 21 days followed by 20mg oral daily or continuation on unfractioned heparin or low-molecular weight heparin with initiation of warfarin adjusted to INR of 2-3. Blood samples will be taken within 2 hours of CDT completion prior to receipt of study treatment (study day 1), at 8h-12h, 24h, 48h, 5d (or prior to hospital discharge), and at 30 day follow-up. Clinical endpoints, including bleeding, evidence of thrombosis progression, and death will be tracked during index hospitalization and at follow-up 30 days post-discharge.
The aim of this study is to clarify the efficacy of the endovascular treatment for acute ischemic stroke patients with large vessel occlusion and are not respond to intravenous recombinant tissue plasminogen activator (rt-PA) therapy.
The purpose of this study is to evaluate the safety and effectiveness of the LUMIFI with Crux VCF System for deployment of the Crux VCF. The study will compare the method of Crux VCF deployment using the LUMIFI with Crux VCF System (IVUS guidance) with the historical results of the Crux VCF System (fluoroscopic guidance). The study will include enrollment into a roll in phase consisting of 2 study subjects per site prior to enrollment into the primary treatment phase for primary analyses. The purpose of the roll in phase is to assure compliance with site training on the use of the investigational device and protocol workflow.
