Filter by:About half of patients who suffer of a pulmonary embolism (blood clots in the lungs), do not clear completely the clots overtime, increasing the risk of having a new blood clot in the lungs and elevated blood pressure in the pulmonary artery; therefore, developing fatigue, shortness of breath, and heart failure. The objective of this clinical trial is to compare 3 months of daily Macitentan (a medicine to increase the diameter of the pulmonary artery) in addition to blood thinners vs. blood thinners alone in patients with acute blood clots in the pulmonary artery: Question 1: Whether the use of Macitentan in addition to blood thinners enhances the process of cleaning the blood clot in the pulmonary artery compared to blood thinners alone. Question 2: Whether the use of Macitentan in addition to blood thinners is associated to improve the fatigue and shortness of breath in patients after a pulmonary embolism compared to blood thinners alone. Participants will be asked to take a capsule for 3 months in addition to blood thinners. The capsule could contain either Macitentan (medicine) or a placebo (not medicine). In 3 months, participants will have a new image of the pulmonary artery to document the cleaning of the clots. Also, blood and urine samples will be collected, as well as a questionnaire will be filled out. In 6 months, patients will have repeated images of the heart as well as repeated questionnaires.
A single center study to evaluate the effect of inhaled nitric oxide (iNO) on pulmonary dynamics in patients presenting with imaging confirmed intermediate/submassive or massive pulmonary embolism (PE). The target enrollment is 20 subjects at Ronald Reagan UCLA Medical Center. PE patients undergoing catheter-based intervention will be administered iNO during their intervention and pulmonary hemodynamic measurement will be measured before, during, and after iNO administration (Invasive Cohort). Patients who are not undergoing catheter-based intervention will also be administered iNO and will have pulmonary hemodynamics, blood pressure, and heart rate measured non-invasively (Non-Invasive Cohort).
To determine if there is any difference in the effectiveness and safety outcomes of patients with NVAF newly treated with apixaban, dabigatran, rivaroxaban and vitamin K antagonists
In a randomized controlled design the study aims to investigate whether an intervention of 8 weeks supervised bicycle training program in addition to usual care can positively influence the physical capacity and quality of life in patients medically treated for pulmonary embolism.
Anticoagulants are a leading cause of acute injury from adverse drug events, leading to ~20,000 serious injuries reported to the Food and Drug Administration per year and more than 220,000 emergency department visits annually. Therefore, we propose to implement a health information technology (HIT) population management tool at two distinct anticoagulation clinics that will allow the care team to assign and track tasks essential for timely patient monitoring. We will examine its effect on anticoagulation management outcomes through a randomized trial, hypothesizing that such interventions can be effective as well as cost-effective strategies to improve patient safety in the context of anticoagulation management services.
Post-surgical bleeding is a major source of morbidity in cancer patients, and ramifications can include need for transfusion, increased length of hospital stay, unexpected return to the operating room, or even death. Current guidelines support that all cancer patients who require surgical procedures receive post-operative blood thinners to minimize risk for blood clots in the legs or lungs, known as venous thromboembolism (VTE), but these medications have an unfavorable risk/benefit relationship among patients at low risk for VTE. The proposed work will pilot a randomized, double blind, placebo controlled trial to critically examine the role of de-implementation of current guidelines that mandate blood thinning medications among cancer patients at low risk for VTE who require surgical procedures; the pilot trial will allow optimization of the design of a future pragmatic multicenter trial, which ultimately would maximize patient safety after surgical procedures for cancer.

Pulmonary Embolism (PE) is a frequent disease, the third cause of cardiovascular death after stroke and myocardial infarction. According to European guidelines of European Society of Cardiology (ESC) and of European Respiratory Society (ERS), the prognostic stratification of PE severity is mandatory as soon as PE is diagnosed. This stratification includes the hemodynamic status, and specific tools : the assessment of the sPESI score, and the evaluation of PE's impact on right ventricle (RV) : increased biomarkers (troponin, BNP) and right ventricle/left ventricle (RV/LV) ratio. the RV/LV ration may be evaluated ideally by transthoracic echo (TTE), or by CT scan. Unfortunately, only 10% of patients with PE are evaluated with TTE by a cardiologist in the initial time of PE diagnosis. Hence, the CT scan is the most frequent way to assess RV/LV ratio. However, CT is not possible for all patients (patients with contra-indication) or may have difficulties to provide a clear assessment because of technical issues. Then, there is a need for morphological evaluation of RV as soon as PE is diagnosed, in every clinical setting. The improvement in technologies allowed the development of clinical echography (CE) in emergency departments. CE is already available, non-invasive, less expansive, and may be a good way to assess RV/LV ratio in patients with PE diagnosed in emergency departments. The investigators propose a prospective, multicenter study to assess the sensitivity of CE in patients with PE, compared to CT scan to detect RV/LV ≥0.9.
The primary objective of this study is to evaluate safety and initial effectiveness of DS-9231 when taken together with current standard of care. Evaluation will be done with low, medium and then high doses of DS-9231 versus placebo, in participants with medium-risk acute pulmonary embolism.
