Ultrasound-accelerated catheter-directed thrombolysis versus anticoagulation for the prevention of post-thrombotic syndrome (CAVA): a single-blind, multicentre, randomised trial

The Lancet Haematology

RCT (184) showed additional ultrasound-accelerated catheter-directed thrombolysis (urokinase) does not change risk of post-thrombotic syndrome 1 year after acute ilio femoral DVT vs. standard therapy (anticoagulation, stockings, early ambulation) [29 vs. 35%; respectively,p=0.42].


Venous thromboembolic diseases: diagnosis, management and thrombophilia testing – DRAFT guidance consultation

National Institute for Health and Care Excellence

This DRAFT guideline aims to support quick diagnosis and effective treatment for people who develop DVT or PE. It also covers testing for conditions that can make a DVT or PE more likely, such as thrombophilia (a blood clotting disorder) and cancer.


Association of Anticoagulant Therapy With Risk of Fracture Among Patients With Atrial Fibrillation

JAMA Internal Medicine

Study (n=167 275) found that relative to new users of warfarin, new users of DOACs - particularly apixaban – were at lower risk of fractures requiring hospitalisation (hazard ratio for DOAC vs. warfarin 0.87; 95% CI, 0.79-0.96).


Comparison of warfarin versus antiplatelet therapy after surgical bioprosthetic aortic valve replacement


Swedish cohort study (n= 9539) reported that warfarin vs single antiplatelet exposure was associated with lower long-term risk of ischaemic stroke and thromboembolic events, and with a higher incidence of bleeding events but with similar mortality.

Optimizing heart failure management: anticoagulation, diuretic withdrawal, iron substitution, and novel inotropes

European Heart Journal

Review discusses management options for heart failure with reduced ejection fraction (HfrEF), whether anticoagulation would be protective in patients with ischaemic HfrEF, role of renin–angiotensin system, beta-blockers, mineralocorticoid receptor antagonists and diuretics.


Manufacturers report positive data from the TWILIGHT trial for ticagrelor


New data from AstraZeneca's TWILIGHT trial has found that Brilinta (ticagrelor) on its own reduced the risk of clinically relevant bleeding compared to dual antiplatelet therapy (DAPT) over 12 months in high-risk patients with non-ST elevation acute coronary syndromes (NSTE-ACS).


A Controlled Trial of Rivaroxaban after Transcatheter Aortic-Valve Replacement

New England Journal of Medicine

In 1644 pts without an established indication for oral anticoagulation after transcatheter aortic-valve replacement, treatment with rivaroxaban was associated with a higher risk of death or thromboembolic complications and higher risk of bleeding vs an antiplatelet-based strategy.


Anticoagulant Reversal Strategies in the Emergency Department Setting: Recommendations of a Multidisciplinary Expert Panel

Annals of Emergency Medicine

This US-focused anticoagulant reversal and replacement guidance statement is supported by literature and consensus definitions to support evaluation and treatment of the bleeding and nonbleeding patient requiring emergency invasive procedures.

DTB Commentary: Intensive antiplatelet therapy with three agents does not reduce risk of another stroke

Drug and Therapeutics Bulletin

A commentary on the Triple Antiplatelets for Reducing Dependency after Ischaemic Stroke (TARDIS) highlights that intensive antiplatelet therapy with three drugs should not be used in routine clinical practice to prevent recurrent events in patients with acute cerebral ischaemia.


Association of Testosterone Therapy With Risk of Venous Thromboembolism Among Men With and Without Hypogonadism

JAMA Internal Medicine

Study (n=39,622) found testosterone therapy was associated with an increase in short-term risk for VTE among men with (OR 2.32; 95% CI, 1.97-2.74) and without (2.02; 1.47-2.77) hypogonadism, with some evidence that the association was more pronounced among younger men.


Adjunctive Antithrombotic Therapy for Patients With Aortic Stenosis Undergoing Transcatheter Aortic Valve Replacement

JAMA Cardiology

Article notes adjunctive antithrombotic therapy used to mitigate thrombotic risks in this population must be balanced against bleeding complications. Evidence for its use remains scarce and no risk prediction models have been established to guide antithrombotic therapy.


Actelion withdraws regulatory filings to extend indication of macitentan in chronic thromboembolic pulmonary hypertension

Biospace Inc.

Feedback from regulatory authorities, and from recent study site inspections indicated that additional clinical data would be required for approval. As a result, Actelion has decided to withdraw ongoing worldwide submissions based on phase 2 MERIT-1 study.

Rivaroxaban compared with standard anticoagulants for the treatment of acute venous thromboembolism in children: a randomised, controlled, phase 3 trial

The Lancet Haematology

RCT (n=500) reports fewer symptomatic recurrent venous thromboembolism rates with rivaroxaban: 1% of 335 children receiving weight-adjusted rivaroxaban vs 3% of 165 receiving standard anticoagulants (HR 0.40, 95% CI 0.11–1.41), with similar rates of bleeding in both groups.

Effect of Fibrinogen Concentrate vs Cryoprecipitate on Blood Component Transfusion After Cardiac Surgery The FIBRES Randomized Clinical Trial

Journal of the American Medical Association

RCT of 735 adults who underwent CABG surgery and developed significant bleeding and hypofibrinogenemia post surgery showed similar number of blood components transfused within 24hrs with both fibrinogen concentrate group and cryoprecipitate group (p<0.01 for non-inferiority).


Management of Nonvariceal Upper Gastrointestinal Bleeding (UGIB): Guideline Recommendations From the International Consensus Group

Annals of Internal Medicine

Recommendations for patients receiving anticoagulation or antiplatelet therapy have been updated. PPI therapy is recommended to prevent UGIB in patients with previous ulcer bleeding who are receiving single- or dual-antiplatelet or anticoagulant therapy.


Prevalence and Knowledge of Potential Interactions Between Over‐the‐Counter Products and Apixaban

Journal of the American Geriatrics Society

Survey (n=791,California) found significant number of patients take OTC meds (particularly dietary supplements) with potentially serious interactions (SIs) with apixaban (33% took ≥1 and 6.7% multiple interacting OTC meds) and they appear to lack knowledge about potentially SIs.


Safety and efficacy outcomes of double vs. triple antithrombotic therapy in patients with atrial fibrillation following percutaneous coronary intervention

European Heart Journal

Review (4 RCTs; n= 10 234) reported lower major or clinically relevant non-major bleeding with double vs. triple antithrombotic therapy (RR 0.66, 95% CI 0.56–0.78; P < 0.0001; I2 = 69%) but at higher risk of stent thrombosis (RR 1.59, 95% CI 1.01–2.50; P = 0.04; I2 = 0%).


NIHR Signal: Significant risk of another thrombosis remains if anticoagulation is stopped

NIHR Dissemination Centre

This expert commentary of a meta-analysis (18 studies, n= 7,515) states clinical decisions to cease anticoagulation should remain tailored to each patient's circumstances and balanced against risk of bleeding.


Pharmacovigilance Risk Assessment Committee (PRAC) recommends Xeljanz (tofacitinib) be used with caution for all patients at high risk of blood clots

European Medicines Agency

PRAC has concluded that tofacitinib could increase risk of blood clots in the lungs and deep veins in patients who are already at high risk. Also, patients older than 65 years of age should be treated with tofacitinib only when there is no alternative treatment.
