Filter by:The primary objective is to evaluate the efficacy of the treatment with supplementary oxygen added to conventional anticoagulant treatment in patients with Intermediate-risk pulmonary embolism. The secondary objective is to evaluate the safety of the treatment with supplementary oxygen added to conventional anticoagulant treatment in patients with Intermediate-risk pulmonary embolism.
This study evaluates the impact of community pharmacists' educational training on the nature and adequacy of counseling provided to patients on warfarin, an oral anticoagulant. Half of the community pharmacists participating in the study will receive a two-week educational training on how to adequately counsel patients on warfarin while the other half of community pharmacists will receive the same training after the study. A mystery patient model will be used in this intervention study where six different trained and standardized individuals will act as patients. Each of these mystery patients will supposedly have pulmonary embolism, deep vein thrombosis, or atrial fibrillation. The mystery patient will visit each pharmacy to buy warfarin or complain about adverse drug reaction been experienced. It is expected that pharmacists will provide relevant information and counseling to these patients on the use of the medication warfarin and how to handle the adverse drug reactions.
To assess the efficacy and safety of endovascular thrombolysis of pulmonary embolism with right ventricular dysfunction with single-dose rtPA
Routine screening for Chronic thromboembolic pulmonary hypertension (CTEPH) i after PE is not supported by current evidence and guidelines. This study aims to evaluate if a screening program for patients with acute PE based on telephone monitoring of symptoms and further examination if only symptomatic patients could help an early detection of CTEPH.
To date, the investigators have successfully employed a radiotracer (18F-sodium fluoride) as a marker of necrotic inflammation in human atherosclerosis. The investigators aim to further the mechanistic understanding of atherothrombosis by studying the activation of glycoprotein IIb/IIIa receptors in cardiovascular thrombus using the novel platelet radiotracer (18F-GP1). Binding of 18F-GP1 to activated platelets in venous and arterial thrombi has already been demonstrated in pre-clinical studies and a phase 1 trial in man. If successful, this study would define the role of the glycoprotein IIb/IIIa receptor within in vivo thrombosis across a range of cardiovascular diseases.
The Bashir™ Endovascular Catheter is a device intended for the localized infusion of therapeutic agents into the pulmonary artery and peripheral vasculature.
This is a prospective, observational, multicenter cohort study to compare right ventricular dysfunction dependent and independent prognostic models for short-term serous adverse events in patients who are diagnosed with pulmonary embolism in the emergency department. Clinical endpoints are assessed at days 1-5. A thirty-day follow-up phone call is conducted to obtain further clinical endpoints and a quality of life assessment.
Study objective is to determine whether there is an association between genetic variant risk scores and clinical outcomes (percent time in therapeutic range, time to reach therapeutic international normalized ratio (INR), INR ≥ 4, bleeding event, ischemic stroke, death) in participants taking warfarin for atrial fibrillation, deep vein thrombosis (DVT), pulmonary embolism (PE), and/or intracardiac thrombosis.
BACKGROUND: Pulmonary embolism (PE) is associated to high mortality rate worldwide. However, the diagnosis of PE often results inaccurate. Many cases of PE are incorrectly diagnosed or missed and they are often associated to sudden unexpected death (SUD). In forensic practice, it is important to establish the time of thrombus formation in order to determine the precise moment of death. The autopsy remains the gold standard method for the identification of death cause allowing the determination of discrepancies between clinical and autopsy diagnoses. The aim of our study will be to verify the morphological and histological criteria of fatal cases of PE and evaluate the dating of thrombus formation considering 5 ranges of time. METHODS: Pulmonary vessels sections will be collected from January 2010 to December 2017. Sections of thrombus sampling will be stained with hematoxylin and eosin. The content of infiltrated cells, fibroblasts and collagen fibers will be scored using a semi-quantitative three-point scale of range values. Hypothesis: After a macroscopic observation and a good sampling traditional histology, it will be important to identify the time of thrombus formation. We will identify histologically a range of time in the physiopathology of the thrombus (early, recent, recent-medium, medium, old), allowing to determine the dating of thrombus formation and the exact time of death.
Pulmonary embolism (PE) can be a devastating postoperative complication and the leading cause of mortality after thoracic surgery. PE together with deep venous thrombosis (DVT) is called venous thromboembolism (VTE), whereas PE caused much more serious situation than DVT. Huge amount of data have demonstrated that thromboprophylaxis after surgery is very important to prevent postoperative VTE, especially after orthopedic surgery and plaster surgery. Moreover, for thoracic surgery, American College of Chest Physicians (ACCP) has published prevention guidelines of VTE in non-orthopedic surgical patients and has been used widely, but unfortunately prophylaxis measures had often been underused in China. However, to be honest, there could be a big difference between Chinese and western populations, for example, what guidelines recommended thrombolysis therapy in diagnosed massive or sub-massive PE patients is tissue type plasminogen activator (t-PA) 100 mg, while in China 50 mg has the same effect. So investigators wanted to establish if the prophylaxis measures what they were using currently are suitable for Chinese thoracic surgical patients.
