Filter by:The purpose of this study is to describe the characteristics of patients treated with different OATs and whether these characteristics differ between treatments. Furthermore to describe persistence to each OAT and risk of bleeding after initiating each OAT.
This will be a retrospective cohort study using national register linkage data (including prescription, inpatient, mortality, and socioeconomic data). The study period will be from May 29, 2013 to June 30, 2015. Patients will be followed from the start of treatment (index date) until their death, exiting the database, or until the end of the study period (June 30, 2015).
To estimate annualized total cost rates (i.e. direct medical costs from hospitalizations, consultations, medications, and tests) of adequately controlling a patient (i.e. INR between 2-3 and TTR≥ 60%) diagnosed with non-valvular atrial fibrillation (NVAF) or venous thromboembolism (VTE), and treated with vitamin K antagonists (VKA) in Spain.
The purpose of this study is to determine the feasibility, safety, and acceptability of implementing an extended interval of INR follow-up in Veterans on a stable dose of warfarin in the Anticoagulation Clinic at the William S. Middleton Memorial Veterans Hospital. All participants will be provided usual care from the anticoagulation clinic, except for the interval between INRs. If the participant continues to be on a stable dose of warfarin and the INRs are within the goal range of 2-3 (including lab variation), follow-up visits will be scheduled following an extended interval protocol. Patient satisfaction will be evaluated at various points throughout the study. Additionally provider satisfaction, confidence, and knowledge of the extended interval protocol will be analyzed. Bleeding and thromboembolic events will be evaluated to ensure the safety of an extended follow-up interval.
The purpose of this study is to assess the effect of two 4-Factor PCC formulations on Apixaban pharmacodynamics in healthy adult subjects.
This cross-sectional epidemiologic study measured physician and patient awareness and understanding of the key messages in the Xarelto prescriber guide and Xarelto patient alert card.
The primary purpose of this protocol is to evaluate the safety of Apixaban in prophylaxis of Venous Thromboembolism (VTE) in Indian patients undergoing elective total knee or hip replacement
The purpose of this observational study is to obtain multi-center data on HeartMate II (HMII) patients managed with reduced anticoagulation or anti-platelet regimes, and the incidence of thrombotic and bleeding adverse events associated with these regimes.
The optimal valve substitute for patients between 60-70 years is controversial. We compared anticoagulation-related adverse events (ARAE) in patients receiving mechanical heart valve replacement (MHVR) on INR self-management vs. stentless bioprosthesis, to assess whether the risk of structural valve deterioration (SVD) is still out-weighted by the benefit of not requiring permanent anticoagulation.
There are currently several schemes described for anticoagulation with heparin and its reversal with protamine during cardiac surgery with CPB. The oldest, and most used in our routine environment, is the scheme of fixed doses, in which a bolus dose of heparin at the start of CPB is established in IU/kg of body weight and the dose of protamine at the end of CPB is calculated based on the initial dose of heparin administered. These schemes do not take into account the variability inter-patients and can result in overdose or sub-doses of one or both drugs. The titration schedule of doses of heparin and protamine through the principle of dose-response curve of Bull promotes individualization of dosage according to the response of each patient. This scheme has been associated with an effective reversal of the effect of heparin after CPB and with reduction of post-operatory bleeding and transfusion. The restoration of a state of anticoagulation by heparin after its reversal by protamine is called "rebound effect". It is a phenomenon explained by the recirculation of heparin stored in the reticulum-endothelial system and connective tissue, or by free residual concentration of heparin after clearance of protamine. This effect may be present for more than 6 hours of post-operatory and may contribute to increase post-operatory bleeding.
