Filter by:The proposed research seeks to provide insights on the contemporary epidemiology, treatment, and outcomes of VTE, including examining the uptake of new treatment strategies, the efficacy and safety of different anticoagulant options, and the impact of venous thromboembolism on patient-defined outcomes, such as quality-of-life, symptom burden, and treatment satisfaction. This information is crucial to helping clinicians and patients choose between various treatment options for venous thromboembolism in order to achieve the best possible balance between the risks, benefits, and impact on health.
In patients with non-valvular atrial fibrillation treated with dabigatran etexilate, the level of adherence will be measured using a questionnaire, the Danish National Prescription Registry and pillcount and will be related to plasma levels of dabigatran measured by liquid chromatography tandem mass spectrometry (LC-MS/MS) and coagulation assays. The aim of the study is to measure the level of adherence and evaluate the usefulness of different coagulation assays to measure adherence in these patients. Furthermore, the aim is to determine the correlation between the anticoagulant effect of dabigatran using different coagulation assays and plasma levels of dabigatran. Most studies so far have been performed in vitro with plasma samples spiked with dabigatran. In this study the present knowledge from results of coagulation assays in dabigatran spiked plasma samples will be compared to the results of coagulation assays using blood samples from real-life patients.
Background: Coagulopathy in chronic kidney disease is multifactorial. Both hypocoagulopathy and hypercoaguability are seen. Conventional tests of coagulation (CCTs) end at the formation of thrombin, and do not take into account the interaction of coagulation factors, platelets, RBC etc. By overcoming the above deficiencies, thromboelastography provides a holistic picture of blood coagulation. The present study evaluated the TEG profile of ESRD patients and compared it to CCTs and to controls. Methods: 50 ESRD patients and 50 controls were recruited for the study. Venous samples were withdrawn and platelet count, INR and fibrinogen levels were measured. Simultaneously a Thromboelastography was performed. All samples were drawn prior to initiation of dialysis.
The investigator is testing blood samples to compare the results of two different techniques. Since blood loss and the need for blood transfusions continue to be major problems after heart surgery and other types of surgery, the blood clotting levels are constantly checked during heart surgery as part of clinical care.The purpose of this study is to compare the INR levels in blood before and after the heart bypass during surgery.
Patients with acute ST-segment elevation myocardial infarction (STEMI) have an elevated risk of stroke, most of which are cardio-embolic in origin as a result of left ventricular (LV) thrombus formation. Anterior-wall location of a MI, in particular, can lead to the complications of LV aneurysm and/or thrombus, which some estimate occurs in approximately up to one-third of individuals within the first 2 weeks following an anterior MI. In the absence of anti coagulation, the risk of embolization in patients with a documented LV thrombus has been reported to be between 10 and 15 percent [3]. Although there are no randomized trials evaluating the efficacy of anticoagulation in patients with an LV thrombus after MI, observational studies provide substantial supporting evidence for the recommendation to anticoagulate patients with documented LV thrombus in order to reduce the risk of embolization. The observation that most events occur within the first three months from the MI forms the basis for the recommendation that anticoagulant therapy should be started early and continued for at least three to six months after myocardial infarction. Currently the practice guidelines recommend anticoagulation after MI only in certain settings such as the presence of LV thrombus or atrial fibrillation. To date there are no data on the use of novel oral anticoagulants (NOACS) for stroke prevention in the setting of LV thrombus after acute MI. The proposed aim of this randomized open label non inferiority clinical trial is to assess whether apixaban is as effective as VKA for the treatment of LV thrombus after acute ST segment elevation MI. Population: Patients with evidence of LV thrombus as assessed by trans-thoracic echocardiography (TTE) 3 to 7 days post admission for acute ST-elevation MI Intervention: The patients will be randomly assigned to treatment with apixaban or s.c enoxaparin 1mg/Kg BID followed by dose-adjusted warfarin to achieve a target international normalized ratio (INR) of 2.0 to 3.0 for 3 months. The study Outcomes are the presence of LV thrombus as assessed be echo, major bleeding, and stroke or systemic embolism and death from any cause.
This trial is conducted in Africa, Asia, Europe and North America. The aim of the trial is to assess the efficacy of concizumab administered s.c. (subcutaneously, under the skin) once daily in preventing bleeding episodes in haemophilia A and B patients with inhibitors.
The trial is conducted in North America. The aim of the trial is to assess the safety of turoctocog alfa under conditions of routine clinical care in patients with haemophilia A in Mexico
Fluids administered intravenously may alter whole blood coagulation. However, little is known about the dose-response relationships of hemodilution in plasmalyte-148 solution. Investigators have therefore performed the present study to measure the effect of a plasmalyte-148 solution on the coagulation pathway according to the hemodilution level using a rotational thromboelastometry (ROTEM®) tests.
The purpose of this study was to establish the normal reference range of Thrombelastogram parameters in Hunan by a multicenter study, and to analyze the specificity of Thrombelastogram detection and the influence of gender, age and blood type on Thrombelastogram. The study will provide basic data and statistical basis for the establishment of normal reference range of Thrombelastogram in Hunan.
While a number of factors are known to be associated with the development of trauma induced coagulopathy (TIC), inflammation, and multi-organ failure, we currently cannot predict which patients are at risk for developing these life threatening conditions with any certainty. In this prospective observational study, we will investigate the many factors that contribute to the development of trauma induced coagulopathy, post injury inflammation and the development of organ dysfunction in order to develop a multi scale computational algorithm of clinical prediction. Using a convenience sample technique, demographic data, physiologic data, blood samples and clinical variables will be collected over 5 days following traumatic injury. A computational model will be used to predict the development of TIC and multi-organ failure.
