Active clinical trials for "Embolism"

Research in acute care faces many challenges, including enrollment challenges, legal limitations in data sharing, limited funding, and lack of singular ownership of the domain of acute care. To overcome some of these challenges, the Center of Acute Care of the University Medical Center Groningen in the Netherlands, has established a de novo data-, image- and biobank named "Acutelines". Acutelines is initiated to improve recognition and treatment of acute diseases and obtain insight in the consequences of acute diseases, including factors predicting its outcome. Thereby, Acutelines contributes to development of personalized treatment and improves prediction of patient outcomes after an acute admission.

This survey will allow to identify PE prognostic, but also long-term complications, i.e. recurrence rate, on-treatment bleedings, deep-vein thrombosis sequella, pulmonary hypertension rate, and chronic pulmonary disease rate without PH. This database should help us identify risk-factors for each event.

This multi-center retrospective study collected clinical, laboratory, and CT pulmonary angiography parameters with acute pulmonary embolism patients from admission to predict adverse outcomes within 30 days after admission into hospital.

Considering observational studies that suggested a relationship between acutely ill medical patients and venous thromboembolism (VTE), interventional studies with anticoagulant medications indicated a marked decline in VTE during and after hospitalization. Despite the therapeutic value of lowering this result, there is a low inclination to utilize anticoagulants in patients hospitalized for acute medical diseases. This observational research aims to assess the appropriateness of venous thromboprophylaxis offered to patients admitted to internal medicine wards.

All calls that end up on the out-of-hours general practitioners' service (OHGPS), which contain a demand for an urgent home visit, are passed on to the on-call general practitioner (GP). These calls are randomized into two arms: after the patient's informed consent, they are assigned either to one arm where the monitoring device, PICO, is applied together with the GP's general care or to the other arm where only the usual care is provided. All data such as suspected diagnosis, treatment or referral, influence of the parameters, ECG and/or alarms on the management and the user-friendliness are recorded. After 30 days, the diagnosis and evolution is requested from the patient's own GP or, if referred to a hospital, in the hospital in order to be able to compare the effect of the approach by the GP between both arms. The aim is to investigate if 1/ the use of the PICO monitoring device could improve GPs' decisions to refer to hospital or not in urgent cases; 2/ there is a difference between the diagnosis with and without the use of the monitoring device using the final diagnosis by the electronic health record of the own GP of the patient; 3/ the call to send a GP for an emergency contained sufficient information for the OHGPS phone operator to take an appropriate decision; 4/ the build-in alarms help the GP during his intervention; 5/ the PICO is easy to use during an emergency; 6/ the use of the device makes them feel more confident in transmitting the information to the Medical Emergency Team.

This study is planned to collect prospective data and evaluate the safety and effectiveness of rivaroxaban for the prevention of stroke and systemic embolism in Indian patients with NVAF when used in clinical practice under real-life conditions. The study will be conducted in routine clinical practice settings. Approximately 1000 patients from India will be enrolled in this study. Patients will be observed for maximum period of 12 months after the start of Xarelto treatment or until it is no longer possible (e.g. lost to follow-up, death, withdrawal) before the end of the observation period. The decision by the investigator to start with of Xarelto must be independent of the inclusion of a patient to the study.

The purpose of this European Post Market Follow-up Plan is designed to evaluate the safety, efficacy, adverse events and any new information that may surface regarding the use of the AngioJet Ultra PE Thrombectomy Catheter System in patients with thrombus in the main pulmonary and lobar arteries ≥ 6mm in diameter.

This is a multi center, prospective study designed to demonstrate the safety and performance of the GARDEX Embolic Protection System when used as an adjunctive device during saphenous vein graft (SVG) interventions.

Background Patients with cancer and a first deep venous thrombosis of the leg or pulmonary embolism (venous thromboembolism, VTE) are generally treated with low molecular weight heparin (LMWH)injections for 6 months, since this treatment is associated with a reduced incidence of recurrent VTE compared to vitamin K antagonists (VKA). It is recommended that patients with active malignancy (metastatic cancer and/or ongoing cancer treatment)continue anticoagulant treatment. However, it is unknown whether LMWH is still superior compared to VKA for the long-term anticoagulant treatment. Aim The aim of this study is to evaluate whether low-molecular-weight heparin more effectively reduces recurrent VTE compared to vitamin K antagonists in patients with cancer who have already completed 6 to 12 months of anticoagulant treatment because of deep venous thrombosis of the leg or pulmonary embolism. Hypothesis The investigators hypothesize that LMWH is more effective compared to VKA in the long-term treatment of VTE in cancer patients who have already been treated for 6-12 months with anticoagulants. Design This is a multicenter, multinational, randomized, open label trial. Patients Patients with a malignancy (all types, solid and hematological) who have received 6-12 months of anticoagulation for VTE and have an indication for continuing anticoagulation, will be randomly assigned to six additional months of LMWH or VKA. LMWH will be administered in a weight-adjusted scheme, with 65-75% of therapeutic doses. All types of LMWH and VKA are allowed, as long as weight adjusted dosing is possible for LMWH. The target INR will be 2.0-3.0. The primary efficacy outcome is symptomatic recurrent VTE, i.e. deep vein thrombosis and pulmonary embolism. The primary safety outcome is major bleeding. Sample size A total of 65 to 87 recurrent VTE events are needed to show a 50% reduction with LMWH as compared to VKA (type I error 0.05, two-sided, power respectively 80 and 90%). To observe 75 events, with a 10% event rate per half year in the VKA arm and 5% in the LMWH arm a total of 1000 patients will need to be included. Organisation Outcomes will be adjudicated by a central adjudication committee. A steering committee will be formed, preferably consisting of one member of every participating center. An electronic case report form will be used for data collection. Also, an electronic trial master file will be used.

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
