Temporal trends in anticoagulation use and clinical outcomes among medicare beneficiaries with non-valvular atrial fibrillation
ConclusionsThe proportions of patients with non-valvular atrial fibrillation who were not prescribed an oral anticoagulant decreased but remained high. We observed an increase in direct oral anticoagulant use that coincided with decreased incidence of clinical outcomes as well as decreasing total healthcare costs.

Effectiveness and safety of direct oral anticoagulants versus warfarin in patients with atrial fibrillation and advanced kidney disease
ConclusionAmong patients with AF and AKD, DOACs were linked to a lower risk of ischemic events, and apixaban was linked to a lower risk of any ischemia and any bleeding than warfarin.

Reduced dose direct oral anticoagulants compared with warfarin with high time in therapeutic range in nonvalvular atrial fibrillation
The objective of this study was to compare effectiveness and safety between reduced dose DOACs and high TTR warfarin treatment (TTR ≥ 70%) in NVAF. A Swedish anticoagulation registry was used in identifying eligible patients from July 2011 to December 2017. The study cohort consisted of 40,564 patients with newly initiated DOAC (apixaban, dabigatran, or rivaroxaban) (11,083 patients) or warfarin treatment (29,481 patients ) after exclusion of 374,135 patients due to not being warfarin or DOAC naïve, not being prescribed reduced dose, having previous mechanical heart valve (MHV), or being under 18 years old. The me...

Effectiveness and safety of direct oral anticoagulants in patients with venous thromboembolism and creatinine clearance & lt; 30 mL/min
AbstractThe few studies that compared direct oral anticoagulants (DOAC) vs. warfarin in the setting of advanced renal insufficiency have focused on patients with atrial fibrillation. The purpose of this observational, matched, cohort study of patients was to assess the effectiveness and safety of DOAC vs. warfarin for the treatment of venous thromboembolism (VTE) among patients with a creatinine clearance (CrCl) < 30 mL/min. This observational, cohort study included patients with VTE and CrCl < 30 mL/min who were newly initiated on a DOAC or warfarin between January 1, 2016 and December 31, 2020. DOAC pati...

Effectiveness and safety of oral anticoagulants in non-valvular atrial fibrillation patients with prior bleeding events: a retrospective analysis of administrative claims databases
ConclusionsIn this real-world analysis of a large sample of NVAF patients with prior bleeding, NOACs were associated with similar or lower risk of stroke/SE and MB vs. warfarin and variable risk of stroke/SE and MB against each other.

Prescribing of anticoagulation for atrial fibrillation in primary care
The objective of this study was to describe anticoagulation prescribing by primary care physicians. We conducted an observational study in the Cleveland Clinic Health System among patients with AF and ≥ 1 primary care appointment between 2015 and 2018 and their physicians. We estimated differences in the odds of an eligible patient receiving anticoagulation versus not and a DOAC versus warfarin using two mixed effects logistic regression models, adjusted for patient sociodemographic factor s, history of falls or dementia, and CHA2DS2-VASc and HAS-BLED scores. We categorized physicians into prescribing tertiles, base...

Delayed diagnosis of congenital thrombotic thrombocytopenic purpura in a patient with recurrent strokes
AbstractCongenital thrombotic thrombocytopenic purpura (cTTP) is caused by ADAMTS13 mutations and associated with high risk of microvascular thrombosis. A 58 year old female had an ischemic stroke during hormonal fertility, and a TIA a year after. She suffered another stroke 18 years later while on warfarin. Four months after she developed severe thrombocytopenia, mild anemia, and increased LDH. Blood film showed schistocytes. She was hospitalized wit h presumptive TTP. ADAMTS 13 activity was undetectable without inhibitor. She developed another stroke and received plasma exchange. A homozygote ADAMTS 13 mutation was id...

Examination of anticoagulation prescription among elderly patients with atrial fibrillation after in-hospital fall
AbstractMechanical fall is common among elders and has been associated with a lack of anticoagulant therapy among patients with atrial fibrillation (AF). However, anticoagulant therapy is recommended despite frequent fall due to an increased risk of a thromboembolic event. Using data from a large health system, we investigated the predictors of anticoagulation prescription on discharge in AF elderly patients after an in-hospital fall. In this retrospective analysis, we examined patients aged 60 years and older discharged from 2013 to 2018 with a diagnosis of AF and a secondary diagnosis of in-hospital fall. The primary o...

The outcomes of three-factor prothrombin complex concentrate (3F-PCC) in warfarin anticoagulation reversal: a prospective, single-arm, open-label, multicentre study
AbstractThere is a wide variation on the efficacy of three-factor Prothrombin Complex Concentrate (3F-PCC) in warfarin reversal. We aimed to determine the efficacy and safety of 3F-PCC in warfarin reversal. This multicentre prospective study analysed data from adult patients on warfarin who received 3F-PCC (Prothrombinex-VF ®) for anticoagulation reversal between June 2019 to October 2020. Purposive sampling was used in this study. Study endpoints included target INR achievement, adverse drug reactions (ADRs), and in-hospital all-cause mortality. Logistic regression analyses were used to assess independent predictors of s...

Short-term non-vitamin K antagonist oral anticoagulants vs. warfarin in preventing device-related thrombosis after left atrial appendage closure
AbstractUp to now we have had few evidences on the Non-vitamin K Antagonist Oral Anticoagulants (NOACs) ’ efficacy and safety in preventing device-related thrombosis (DRT) after percutaneous left atrial appendage closure (LAAC). After LAAC implantation, short-term anticoagulation (NOACs or warfarin) was prescribed. Baseline clinical characteristics, procedural parameters and postoperative follow up data were collected and compared between the two groups. From May 2014 to June 2018, 361 consecutive patients underwent LAAC implantation in our center. 170 patients received warfarin for 45 days at least after LAAC implantat...

Comparative effectiveness of direct oral anticoagulants and warfarin for the treatment of left ventricular thrombus
AbstractLeft ventricular (LV) thrombus is a complication of acute endomyocardial injury and chronic ventricular wall hypokinesis, resulting in increased risk of thromboembolic complications. Observational studies support the general safety and efficacy of warfarin for this indication. Limited data exists regarding the use of direct oral anticoagulants (DOACs) for LV thrombus. This retrospective cohort study sought to compare the incidence of thromboembolic events, bleeding rates, and blood product administration in patients receiving a DOAC versus warfarin. A total of 949 patients met inclusion, 180 (19%) received a DOAC a...

Bleeding risk in patients with venous thromboembolic events treated with new oral anticoagulants
AbstractNew oral anticoagulants (NOACs) is the preferred treatment in secondary prophylaxis of venous thromboembolic events (VTE). The aim of this study was to investigate possible risk factors associated with major bleeding in VTE-patients treated with NOACs. In this retrospective register-based study we screened the Swedish anticoagulation registerAuricula (during 2012.01.01 –2017.12.31) to find patients and used other national registers for outcomes. Primary endpoint was major bleeding defined as bleeding leading to hospital care. Multivariate Cox-regression analysis was used to reveal risk factors. 18 219 patients wi...

Associations between model-predicted rivaroxaban exposure and patient characteristics and efficacy and safety outcomes in patients with non-valvular atrial fibrillation
This study aimed to quantify associations between model-predicted rivaroxaban exposure and patient characteristics and efficacy and safety outcomes in patients with non-valvular atrial fibrillation (NVAF), using data from the phase 3 ROCKET AF trial (NCT00403767). In ROCKET AF, 14,2 64 patients with NVAF were randomized to rivaroxaban (20 mg once daily [OD], or 15 mg OD if creatinine clearance was 30–49 mL/min) or dose-adjusted warfarin (median follow-up: 707 days); rivaroxaban plasma concentration was measured in a subset of 161 patients. In this post hoc exposure–resp onse analysis, a multivariate Cox model was u...
