Applying Pharmacogenetics to Warfarin Dosing in Chinese Patients

Atrial FibrillationDeep Vein Thrombosis2 more

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.

VERITAS: An Evaluation of the Veniti Vidi Retrievable Inferior Vena Cava Filter System in Patients...

Deep Vein ThrombosisPulmonary Embolus

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.

Home Treatment of Pulmonary Embolism

Pulmonary Embolism

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

Risk Stratification for Patients Presenting With Acute Pulmonary Embolism (PE)

Pulmonary Embolism

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.

Modeling Genotype and Other Factors to Enhance the Safety of Coumadin Prescribing

Atrial FibrillationDeep Venous Thrombosis2 more

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.

DVT - Deep Vein ThrombosisPE - Pulmonary Thromboembolism

The Purpose is to compare the safety and efficacy of the use of aspirin(ASA) with medical compression devices versus aspirin alone for venous thromboprophylaxis following knee and hip arthroplasty.

Efficacy and Safety of Half Dose Alteplase Added to Heparine, in Patients With Moderate Pulmonary...

Pulmonary Embolism

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

Use of Gadolinium in CT Pulmonary Angiography

Pulmonary Embolism

The study will investigate patients with clinical suspicion for pulmonary embolism (PE) who have a contraindication to iodine based contrast. These patients normally get investigated with studies such as ultrasound and nuclear medicine studies but the fastest and preferred investigation is CT with contrast to look for filling defects in the pulmonary arteries. The investigators will assess whether gadolinium, which is currently used with MRI can be used with CT as an alternative effective contrast in diagnosis or exclusion of PE. A new type of CT scanner, a Dual Energy Scanner will be used to improve the visibility of Gadolinium contrast on CT.

CT for Pulmonary Thromboembolic Disease

Pulmonary Embolism

Examine the feasibility and efficacy of individually optimized uniform contrast enhancement in CT pulmonary angiography (CTPA) for the diagnosis of pulmonary thromboembolic disease.

Low Dose Rt-PA for Acute Normotensive Pulmonary Embolism With RVD

Pulmonary ThromboembolismsPulmonary Embolism

In selected patients with acute pulmonary embolism(PE), low dose (50mg/2h) recombinant tissue plasminogen activator (rt-PA) regimen had been reported to have less bleeding tendency than the FDA-approved rt-PA 100mg/2h regimen 100mg/2h regimen (3% vs.10%), it is worthwhile to reveal whether low dose rt-PA plus low molecular weight heparin (LMWH) can rapidly reverses RV pressure overload in PE, but not increase bleeding and other adverse events. The aim of the study is to compare thrombolytic treatment with LMWH in patients with acute normotensive PE with right ventricular dysfunction(RVD).
