Filter by:Researchers are looking for a better way to treat people with atrial fibrillation and prevent stroke or systemic embolism (blood clots travelling through the blood stream to plug another vessel). Atrial fibrillation is a condition of having irregular and often rapid heartbeat. It can lead to the formation of blood clots in the heart which can travel through the blood stream to plug another vessel, and like this lead to serious and life-threatening conditions, such as a stroke. A stroke occurs because the brain tissue beyond the blockage no longer receives nutrients and oxygen so that brain cells die. As strokes arising from atrial fibrillation can involve extensive areas of the brain, it is important to prevent them. Blood clots are formed in a process known as coagulation. Medications are already available to prevent the formation of blood clots. When taken by mouth (orally), they are known as oral anticoagulants (OACs) including apixaban. OACs decrease the risk of the above-mentioned serious and life-threatening conditions. The main side effect of OACs is an increase of the risk of bleeding. The study treatment asundexian is a new type of anticoagulant currently under development to provide further treatment options. Asundexian aims to further improve the standard of care with regard to the risk of bleeding. The main purpose of this study is to collect more data about how well asundexian works to prevent stroke and systemic embolism and how safe it is compared to apixaban in people with atrial fibrillation and at high risk for stroke. To see how well the study treatment asundexian works researchers compare: - how long asundexian works well and - how long apixaban works well after the start of the treatment. Working well means that the treatments can prevent the following from happening: - stroke and/or - systemic embolism. The study will keep collecting data until a certain number of strokes or embolisms happen in the study. To see how safe asundexian is, the researchers will compare how often major bleedings occur after taking the study treatments asundexian and apixaban, respectively. Major bleedings are bleedings that have a serious or even life-threatening impact on a person's health. The study participants will be randomly (by chance) assigned to 1 of 2 treatment groups, A and B. Dependent on the treatment group, the participants will either take the study treatment asundexian by mouth once a day or apixaban by mouth twice a day for approximately 9 - 33 months. Each participant will be in the study for approximately 9 - 34 months. There will be visits to the study site every 3 to 6 months and up to 7 phone calls. Those participants who do not want or are unable to have visits to the study site may join the study remotely in selected locations. The location name contains the abbreviation - DCT in such cases. During the study, the study team will: - take blood samples - do physical examinations - examine heart health using an electrocardiogram (ECG) - check vital signs such as blood pressure and heart rate - do pregnancy tests - ask the participants questions about their quality of life - ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments.
In an open-label parallel groups blinded-endpoint randomized clinical trial, the investigators aim to assess the safety and efficacy of conventional catheter-directed thrombolysis (CDT) vs anticoagulation monotherapy on outcomes of patients with acute intermediate-high risk pulmonary embolism. The investigators hypothesize that CDT will have a superior efficacy and safety compared with anticoagulation-only therapy regarding the proportion of patients with a right ventricle to left ventricle (RV/LV) ratio > 0.9 at a 3-month follow-up by an imaging core laboratory, major bleeding, severe thrombocytopenia, or vascular access complication.
- There is a knowledge gap associated with the management of patients with COVID-19 lung injury and a laboratory picture compatible with disseminated intravascular coagulation (DIC). Clinical data to date support that COVID-19 is associated with a prothrombotic state that is not simply explained by an influx of more critically ill individuals. - These patients suffer from severe respiratory failure; hypoxemia and ventilator dependence are the primary concerns; ARDS with respiratory failure is frequently the cause of death. Macroscopic and probable microvascular thromboembolic events are a major concern in this population. - When DIC is associated with COVID-19, it predicts a very poor prognosis. - This study will evaluate the clinical efficacy and safety of low-dose IV bolus tenecteplase (TNK) together with anticoagulation compared with control patients on therapeutic anticoagulation alone in hospitalized adults diagnosed with COVID-19 and acute intermediate-risk PE. - Prospective, multicenter, randomized two-arm trial enrolling consecutive patients who meet enrollment criteria. - The study will generate evidence that low-dose TNK together with anticoagulation is beneficial in these patients
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.
The purpose of this study is to examine the degree to which pulmonary embolism (clot) can be dissolved when treated with a very low dose of a systemic thrombolytic drug (clot buster) along with standard anticoagulant therapy as compared to the standard of care anticoagulant therapy alone.
The primary purpose of this study is to evaluate the diagnostic performance of three methods for measuring right ventricular size and function including the Philips Novel RV quantification technologies (RV Heart Model volumetric analysis and Philips 2D strain) and the Upper Valley Right Ventricle Algorithm (UVRV) algorithm as compared to the gold standard of volumetric analysis via cardiac magnetic resonance imaging (CMR) in a broad patient population.
The purpose of this study is to evaluate the prevalence rate of pulmonary embolism among not anticoagulated patient older than 75 years old admitted with syncope and hospitalised in the Toulon Hospital
Patients with newly diagnosed pulmonary embolism and high thromboembolic risk will be randomized to screening for atrial fibrillation or standard of care using intermittent ECG registration for at least two weeks.
The PREVENTER Trial aims to compare the use of perioperative pharmacologic prophylaxis (subcutaneous heparin) with intermittent pneumatic compression devices (IPCs) to the use of IPCs alone for the prevention of venous thromboembolism (VTE) after radical prostatectomy (RP).
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).
