Noel, PharmD, BCCP Multiple studies have been published evaluating antithrombotic strategies in patients following transcatheter aortic valve replacement (TAVR) since the release of the 2017 American Heart Association (AHA)/American College of Cardiology (ACC) Focused Update
Use of oral anticoagulation therapy in patients with liver disease is complex. The risks and benefits of therapy need to be considered as those with liver disease can be at heightended risk of bleeding. This blog post will review the literature surrounding the use of oral anticoagulation in patients with atrial fibrillation and liver disease and recommendations on selecting therapy, if any, will be discussed.
The optimal antithrombotic regimen in patients with AF and comorbid CAD remains unclear. Current American College of Cardiology/American Heart Association guidelines provide minimal guidance on whether to continue antiplatelet therapy in combination with anticoagulation in this population. Additionally, while the 2017 European Society of Cardiology guidelines recommend oral anticoagulation alone, there is little supporting evidence for this recommendation. This blog discusses the implications of the recently published AFIRE study, which attempts to answer the question: In patients with stable CAD and AF, is combination therapy necessary or is anticoagulation monotherapy sufficient?
Patients with active cancer are at an increased risk of arterial and venous thromboembolism (VTE) and bleeding events. Until recently, low molecular weight heparins (LMWH) were generally the preferred therapeutic class for treatment of VTE in patients with cancer. However, LMWH use is limited in the outpatient setting by parenteral administration. Recently, direct oral anticoagulants (DOACs) have demonstrated efficacy in large randomized clinical trials of patients with both VTE and atrial fibrillation and are recommended over warfarin in certain populations. Given the attractive oral dosing option and lack of laboratory montioring, DOAC use have been used for VTE treatment for patients with cancer. In this blog, we summarize the available trial data and provide clinical recommendations for VTE treatment in patients with cancer.
When it comes to triple therapy, the totality of the evidence strongly suggests “less is more”. While many practitioners have been quick to adopt dual antithrombotic therapy, it is important to consider the external validity of these trials and how we apply them to our patients. In this blog, Dr. Noel offers 3 considerations that require careful reflection before throwing in the towel on triple therapy.
Part III of this three part series focuses on the role of warfarin in end stage renal disease (ESRD). Is it time to retire warfarin for anticoagulation in patients with ESRD and atrial fibrillation (AF)? Are there supporting data for warfarin in patients with ESRD? How does it compare to apixaban? Check out the blog for full details and answers to these questions.
Part II of this three part series focuses on apixaban in end stage renal disease. Is it safe? How does it compare to warfarin? What dose should you use? Check out the blog for full details and answers to these questions.
Selecting the best anticoagulation strategy for patients with end stage renal disease and atrial fibrillation remains controversial. In this three part series, we will explore potential strategies that seek to balance the risk of stroke with adverse effects in patients with end stage renal disease and atrial fibrillation. In Part 1 of this series, we will discuss the risks of anticoagulation and provide a compelling argument for avoiding anticoagulation. The role of direct oral anticoagulants and warfarin in this patient population will be reviewed in Parts 2 and 3, respectively.
Transcatheter aortic valve replacement (TAVR) has proven to be an effective treatment option for patients with severe aortic stenosis at intermediate-high risk for complications with surgical aortic valve replacement. In spite of the growing popularity of TAVR, the optimal antithrombotic regimen remains unknown. This blog outlines current guideline recommendations for post-TAVR antithrombotic therapy and gives guidance on how to handle special populations and patient-specific factors.
Although guidelines for the management of atrial fibrillation advocate for anticoagulation in patients with a high stroke risk (CHA2DS2-VASc score of 2 or greater), the recommendations for patients at low (CHA2DS2-VASc 0) and in particular intermediate (CHA2DS2-VASc 1) risk of stroke are less clear. In this blog, we discuss antithrombotic strategies in these latter two subgroups.
