Active clinical trials for "Embolism"

The response to warfarin varies greatly among individuals. Some of this variability can be ascribed to genetic polymorphisms in the gene encoding for CYP2C9, the enzyme mediating the metabolism of S warfarin. In addition genetic polymorphism in other genes (i.e. VKORC1, factor VII) have been shown to account for some of the variability in the response to warfarin irrespective of CYP2C9.The present study has several segments: Evaluation of the relationship between genetic polymorphisms in the genes encoding for CYP2C9, VKORC1 and factor VII and warfarin maintenance dose at steady state. This study is a confirmation of previous data in our own population. Evaluation of relationship between genetic polymorphisms in the genes encoding for CYP2C9, VKORC1 and factor VII and warfarin loading dose during the induction period. Testing the hypothesis that warfarin loading based on the individual's combined CYP2C9, VKORC1 and factor VII genotype may be more efficient and associated with reduced adverse drug effects.

Pulmonary embolism (PE) is a pulmonary vascular disease that seriously endangers human health. It has the characteristics of high morbidity, high mortality, high misdiagnosis rate and low detection rate. The mortality rate in March is about 10%. The high-risk and high-risk PE mortality rate is greater than 15%. Chronic thromboembolic pulmonary hypertension (CTEPH) is a serious sequelae after PE, with a poor prognosis and expensive treatment. Systemic thrombolysis is the preferred treatment for acute high-risk pulmonary embolism, which can reduce mortality, but the incidence of major bleeding is increased by 5 times and hemorrhagic stroke is increased by 10 times. Recent studies have concluded that interventional therapy is a viable approach with a high success rate, effective improvement of clinical outcomes, and minimization of major bleeding risks. However, there is no good prospective study of interventional therapy compared with systemic thrombolytic therapy. This study was enrolled in the diagnosis of high-risk and high-risk PE patients, randomized to the system of thrombolytic therapy or interventional therapy (including pulmonary artery catheter contact thrombolysis, catheter thrombectomy, thrombus aspiration and mechanical thrombectomy, etc.) Symptoms improved during surgery, right heart condition, mortality and complications, and were followed up to December to observe PE recurrence CETPH, survival and cardiopulmonary function. In order to provide new evidence for the treatment of fatal pulmonary embolism.

Pilot randomized study of the sidlenafil efficacy in combination with oral anticoagulants in the treatment of patients with intermediate-high risk of pulmonary embolism

The aim of this study is to evaluate efficacy and safety of blood purification therapy on renal dysfunction by cholesterol crystal embolism.

The purpose of this study is to determine whether pharmacogenetic guided dosing of warfarin is promising for the improvement of efficiency, therapeutic efficacy, and, especially, safety of warfarin therapy than a dosing regimen without the pharmacogenetic information in Chinese patients initiated on warfarin anticoagulation.

This is a prospective, multicenter single arm, nonrandomized study that will include 150 patients at a maximum of 20 investigational sites. It is estimated that it may take 13 months to complete enrollment. Follow-up will continue through 24 months post-implant or one month post-retrieval, whichever occurs first. It is required that filters be retrieved from at least 50 patients and the filter is permanent in at least 50 patients.

The best management in selected patients of pulmonary Embolism (PE) should be at home. The efficacy and safety treatment´s at home versus at hospital should be similar and quality of life should be better. Our purpose is to demostrate that Low weight molecular heparin (LWMH) at home for PE is at least as effective and safe at home as at hospital

Hypothesis: Increases in CRP, trop T, and BNP values will correlate significantly with right heart failure on echocardiogram and with mortality, ICU stay, hospital stay, and escalations in care. Evaluate whether CRP, trop T, and BNP correlate significantly with right heart failure on echocardiogram. Evaluate whether CRP, trop T, BNP, and echocardiogram correlate significantly with clinical outcomes: mortality, ICU stay, hospital stay, and escalations in care. Compare each test's correlation with clinical outcomes to the others, to determine which test provides the best risk ratio. Compare each trop T value's correlation with echo findings and clinical outcomes to determine the optimal time to draw trop T levels on a patient presenting with acute PE. These tests will not be used in an attempt to establish a diagnosis of PE.

The study goal is to conduct a randomized controlled trial to compare safety and accuracy of dosing based on clinical information including the clinical reason for your taking coumadin, your age, gender, your body surface area, and other medical conditions you may have with dosing estimated by a dosing calculator which adjusts for factors affecting coumadin dosing variability including genotypes for genes important in Coumadin metabolism and response. The hypothesis to be tested by this trial states that:when compared to patients managed with a best practices standard-of-care coumadin dosing regimen, patients randomized to coumadin dosing based on genetically programmed metabolic capacity and other known clinical and environmental factors affecting dose will: 1)show reduced risk of adverse events (using surrogate measures of such events); and 2)more rapidly achieve Coumadin dosing.

The primary aim of this study is to evaluate whether mid dose (safe dose) of Alteplase in addition to standard treatment with heparin (LMWH) in patients with pulmonary embolism (PE) at intermediate risk, it is effective to reduce: right ventricular dysfunction pulmonary hypertension 24 hours and 7 days after the treatment PE recurrence to 7days and 30 days after the treatment without increasing the incidence of bleeding intra-extracranial
