Active clinical trials for "Pulmonary Embolism"

DESIGN: An IRB-approved, HIPAA-compliant prospective randomized controlled trial conducted from January 1, 2012-December 31, 2013. SETTING: The ED of an urban Level-I adult trauma center with existing CDS for CTPE. PARTICIPANTS: All attending physicians were stratified into quartiles by 2012 CTPE use and randomized to receive feedback reporting or not. INTERVENTION: Quarterly performance feedback reports consisting of individual and anonymized group data on EBG adherence (using the Wells criteria), CTPE use (CTPEs per 1,000 patients), and yield (percentage of CTPEs positive for PE) beginning January 2013.

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.

This study is designed to determine the safety, pharmacokinetics and pharmacodynamics of a single intravenous dose of TS23 in healthy adults.

The purpose of this trial is to compare the efficacy and safety of Recombinant Human Tissue-Type Plasminogen Activator Derivative(rPA) and Recombinant Tissue-Type Plasminogen Activator(rt-PA) for the treatment of acute pulmonary embolism. This trial includes two stages, the first stage is to study the dosage of administration of the test drug(rPA), the second is to compare the efficacy and safety of rPA and rt-PA. Both of the two stages are randomized, open and parallel controlled.

Viral infections provoke the systemic inflammatory response and cause an imbalance between the procoagulant and anticoagulant homeostatic mechanisms. Multiple pathogenic mechanisms are involved, including endothelial dysfunction, increased von Willebrand factor, Toll receptor activation, and tissue factor pathway activation. D-dimer levels greater than 1000 ng / mL are associated with an 18-fold increased risk of mortality. In this context, many patients may require prophylaxis or antithrombotic treatment with low molecular weight heparins. Currently, there is no validated scheme on the dose and timing of the use of antithrombotic drugs. The study aims to identify the effect of two anticoagulant strategies (prophylactic and therapeutic) on the progression to ventilatory support or death in patients with COVID-19 infection who require hospital care.

The aim of the present study was to assess the effects of low-dose (25mg) prolonged administration (in 6 hours) of tissue type plasminogen activator (tPA) on in-hospital mortality and outcomes in patients with massive PE.

With the improvement in CT scanners and injectors, diagnostic chest CT can now be performed in less than 10 seconds. It was hypothesized that diagnostic CT pulmonary angiograms could be done with less than the usual 80-120 ml of contrast used. We have developed a method of performing diagnostic CT pulmonary angiograms with 30 ml of intravenous contrast in most patients. The long-term objective of this study is to show that there is no difference in the diagnostic efficacy of this low dose 30 ml technique when compared to the more traditional full-dose technique.

The purpose of this study is to determine whether a limited duration of treatment (two weeks of low molecular weight treatment) is a safe and effective treatment for distal deep vein thrombosis of the lower limb.

There is a clear link between obstructive sleep apnea (OSA) and cardiovascular disease. However, there has been no clear link between OSA and venous thromboembolism (VTE). The objective of this study is to evaluate such a link.

The purpose of this research is to find a better way to prevent the post operative development of clots in the deep veins of the legs (also called Deep Vein Thrombosis or DVT). DVT causes redness, swelling, and pain in the involved leg(s). Long-term complications may include permanent swelling and pain of the leg(s), and even skin ulcers around the ankle. If clots form in a leg after surgery, and break off, they can move to the lungs and block the pulmonary artery (also called Pulmonary Emboli or PE). With PE there can be chest pain, chest tightness, shortness of breath, coughing up blood, heart failure, and occasionally death. Doctors have studied ways to reduce these complications. These studies led to the development of drugs which interfere with your body's clotting processes. However, it is still unclear which drug and which drug schedule is best. This study will evaluate two of the standard FDA approved drugs using different dosing schedules.
