Active clinical trials for "Pulmonary Embolism"

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.

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.

The overall goal of the VVIRTUOSO study is to determine the incidence of VTE including symptomatic DVT and PE after hospital discharge in patients with COVID-19 by implementing a pragmatic patient-centred prospective virtual VTE monitoring program in Canada and the United States.

This study is looking at the safety and effectiveness of treating Patients diagnosed with a low-risk Pulmonary Embolism (PE) in an outpatient setting instead of the standard, in-patient hospitalization. Patients have several medical tests done during their Emergency Department visit. Based on those tests, those who are determined to have a low-risk PE are eligible to participate in the study. Those choosing to participate are discharged after 12 hours of medical observation. Patients who choose to participate are followed up by telephone approximately 90 days later.

The current data on the incidence of pulmonary hypertension (PH) are very variable, depending on the different studies designs. There are no data on the prognostic of PH in patients with asymptomatic pulmonary thromboembolisms (PT), neither paucisymptomatic PH, in which without a prospective follow-up would be underdiagnosed. We thought that the prognosis of both clinical forms (PT with or without symptoms) would be similar. The objective of this study is know the real incidence of pulmonary hypertension (PH) post symptomatic and asymptomatic pulmonary thromboembolic (PT).

The primary objective of the study is to report adverse events of on-treatment AEs by the treating physicians during a specified 24-month study period in patients with venous thromboembolism at the sentinel site(s) for the National Center of Pharmacovigilance (CNFV) in Mexico.

The same initial and long-term anticoagulation is suggested for unsuspected pulmonary embolism as for patients with symptomatic embolism. Based on these indications, cancer patients with unsuspected pulmonary embolism would be anticoagulated for at least 6 months or until the disease is active, which in most cases would mean indefinite treatment. In fact, dedicated studies on the treatment of unsuspected pulmonary embolism are missing, leaving doubts over the need for (indefinite) anticoagulation which exposes these patients to an increased risk of major bleeding events. Concerns over the need for anticoagulant treatment may especially hold for pulmonary embolism of the distal pulmonary tree since segmental and sub-segmental PE seem to have a more benign course than more proximal embolism. The scope of this study is to evaluate the current treatment approaches for unsuspected pulmonary embolism and to assess their efficacy and safety in a large prospective cohort of cancer patients.

The investigators are developing a test that is expected to measure the amount of radiation a patient has been exposed to after a nuclear bomb. The investigator will do this by measuring the DNA in the patients blood from cells killed by the radiation. Many diseases and medical conditions can put DNA in the blood. The investigator needs to know how much DNA in order to better interpret our radiation detection test. Therefore, the investigator is collecting blood from several patients with different diseases or medical conditions and also healthy volunteers to measure their DNA content. Patients that will be included in this study are pregnant women, patients who have suffered a pulmonary embolism within the past 48 hours, patients who have suffered from myocardial infarction in the past 48 hours, patients with autoimmune diseases and health patients.

This study aims to evaluate the use of rivaroxaban and its short term safety when used by patients for the new indications of prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation, treatment of deep vein thrombosis (DVT) and pulmonary embolism (PE) and prevention of recurrent DVT and PE. Any adult patient started by their care team on rivaroxaban or an alternative anticoagulant for the specified indications during the study period will be eligible to take part. A questionnaire will be completed by the care team of each patient at the start of treatment and again 12 weeks later. The care team will complete the questionnaires using information from the patient's medical notes, not by asking the patient directly. If a participant has an adverse event during the 12 week period, we may ask the patient's care team to fill out a further follow up questionnaire. No other examinations or tests will be performed. Patients will only be recruited to the study after the clinical decision to prescribe rivaroxaban or an alternative anticoagulant has been made, so that prescribing behaviour is not altered by the study. It is an observational, non-interventional study covering the whole of England and Wales.

This prospective cohort study will provide information about: characteristics of Rivaroxaban use in patients who are prescribed Rivaroxaban for the first time compared to patients who are prescribed Warfarin for the first time, the occurrence of intracranial haemorrhage, gastrointestinal and urogenital bleeding, and the occurrence of non-infective liver disease.
