Active clinical trials for "Thromboembolism"

Participants between the ages of 19 and 70 who were initially diagnosed with venous thromboembolism and were accompanied by dyslipidemia (LDL> = 100 mg / dl) were enrolled. Participants diagnosed with pulmonary embolism, pulmonary embolism CT, and peripheral B-mode ultrasound (B-mode ultrasound) Only participants who do not meet the exclusion criteria should be enrolled in the study. Once the participant is selected, the patient is informed of the study and receives the consent form. Participants who are eligible for all of the criteria and who do not qualify as exclusion criteria should be enrolled in the study and randomly enrolled in a 1: 1 dose of rosuvastatin 20 mg once daily or equivalent. Participants who previously used statins have a wash-out period of two weeks or more Participants undergo a visit at 12 weeks after initiation of treatment. For fasting blood tests, patients visit on an empty stomach. Outpatient follow-up observes side effects after last visit and observes changes in vital signs and weight. After 24 weeks of treatment, the participant visits for efficacy evaluation. We performed body weight, vital signs and blood tests (WBC, hemoglobin, BUN, creatinine, CRP, D-dimer, fibrinogen, PAI-1, AST, ALT, CK, total cholesterol, triglyceride, HDL and LDL). Primary evaluation item: Improvement of venous insufficiency at 6 months Secondary evaluation items: Improvement of blood lipid concentration, inflammation and blood clotting at 6 months Comparison of numerical rate of change Tertiary evaluation items: recurrence of venous thrombosis

Anticoagulants are used to prevent thrombotic events in patients with predisposing factors. However, the use of such therapies is associated with bleeding complications, which can be a serious safety issue. Thus, it is important to evaluate the safety and effectiveness of such therapies based on data collected in clinical practice in order to generate relevant scientific data that could be used to support clinical and regulatory decisions. This is an open, prospective, multicenter, observational cohort study that aims to prospectively record the clinical history of adult patients receiving anticoagulant treatment, irrespectively of the prescribed drug and the indication for its use.

Deep vein Thrombosis (Deep Venous Thrombosis, DVT) and Pulmonary Embolism, Pulmonary Embolism, PE) both collectively known as Venous thromboembolism (VTE) (Venous Thrombus Embolism, VTE), is a common clinical disease, and tremendous harmful. Ankle fractures in patients requiring long-term bed braking, increase the incidence of lower extremity deep vein thrombosis, anticoagulant therapy as an important measures to prevent thrombosis in clinical widely accepted, however, the literature anticoagulation effect incision healing. Whether to strike a balance between the two, to develop a foot fracture in accordance with the Chinese characteristics of anticoagulant solution is we try to solve the problem. The purpose of this study is aimed at the use of oral anticoagulants and physical anticoagulant treatment knee far foot fracture patients randomized controlled studies in China.

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.

The purpose of this trial is to investigate D-Dimer levels, a surrogate marker of venous thromboembolism, in pregnant/postpartum white women as compared to pregnant/postpartum black women, and pregnant/postpartum women with sickle cell trait. The investigators will determine whether increased D-Dimer levels are reflected in a greater incidence of thrombosis in the postpartum patient, as well as the prevalence of symptomatic venous thrombosis in black patients as compared to pregnant white patients and women with sickle cell trait. The investigators will also investigate the effect of blood group on these parameters. If there is evidence that there is an increased risk of thrombosis in sickle cell trait, the investigators will plan a trial of prophylactic anticoagulation during the last trimester and the four weeks post partum for patients with sickle cell trait and compare this population to patients who do not receive prophylactic anticoagulation.

The Venous thromboembolism (VTE) disease is very frequent, mainly as complications of medical diseases and surgical procedures. It has high prevalence and can lead to severe complications such as pulmonary embolism and postthrombotic syndrome. Although its incidence has been decreasing in recent years, the EP and DVT is still a major public health problem, especially in advanced age. The tracking of this disease through imaging tests in asymptomatic patients does not seem to be a cost-effective, further treatment of complications is expensive and subject to no satisfactory answers are not completely effective in regard to late complications. Therefore, according CAIAFA & BASTOS (2002), effective prophylaxis is the best strategy. The type of prevention to be used should be based on the risk of developing VTE, ie low, medium or high. Framework for a category of risk for the indication of prophylaxis, each patient should be evaluated individually and carefully to the risk of developing VTE. Maffei et al. (2005) describe the "Standards for Clinical Guideline for the prevention, diagnosis and treatment of deep vein thrombosis." According to the guide, the concentration of heparin in 5.000UI is indicated for cases of moderate-risk surgeries. Are classified as "moderate risk" to more surgery (general, gynecological and urological) in patients 40 to 60 years without additional risk factors, and the magnitude of any surgery in patients under 40 years of age who use estrogen ( Annex 01). The dosing schedule chosen in this study also follows the recommendation of the guide and is universally used . According to Maffei et al. (2005), the diagnosis of VTE must be initiated by the history and physical examination, and then must be performed ultrasound Doppler of lower limbs. Thus, the ultra-sonography/doppler examination will be done at the beginning and end of treatment and physical examination will be done periodically throughout the period of monitoring. Following the guidelines proposed by the literature consulted, was established to test this methodology, which aims to demonstrate the non inferiority clinical heparin sodium 5.000UI / 0.25 mL sodium heparin on 5.000UI / 1.0 mL, both produced by Blausiegel Industry and Trade Ltda. in reducing the incidence of VTE. The two formulations are produced from the same material, but have different drug concentrations. Thus, there is a need to scientifically prove that the therapeutic activity and safety of the product test is non-inferior to the comparator drug (APP heparina - 5.000 USP/mL), allowing the sponsoring company to obtain the registration of the product in the concentration of 5000UI /0.25 mL in ANVISA at the proposed therapeutic indication in the study.

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

This study compares the efficacy and complication rates of early (24 hours) versus late (72 hours) VTE prophylaxis administration to TBI patients. Patients in both treatment groups will be monitored for development of VTE as well as complications from bleeding after commencement of VTE prophylaxis.

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).

This is a pilot study to determine if anti-thrombin III (AT-III) serum concentrations differ between patients with normal versus subtherapeutic anti-Xa trough concentrations when placed on enoxaparin 30 mg twice daily for VTE prophylaxis. Secondarily, this study will compare two enoxaparin dosing strategies.
