Anticoagulation therapy in heart failure and sinus rhythm: a systematic review and meta-analysis

Heart

Analysis of 5 trials found anticoagulation (AC) reduced rate of non-fatal stroke (RR 0.63, 95% CI, 0.49-0.81, p=0.001) but increased major haemorrhage (1.88; 1.49-2.38, p=0.001). AC did not reduce all-cause mortality, heart failure (re)hospitalisation or non-fatal MI, vs. control.

 

Recurrent Stroke With Rivaroxaban Compared With Aspirin According to Predictors of Atrial Fibrillation: Secondary Analysis of the NAVIGATE ESUS Randomized Clinical Trial

JAMA Neurology

RCT (n=7112) found HAVOC score, left atrial diameter (LAD), and premature atrial contraction frequency predicted subsequent clinical AF. Among subgroup with LAD >4.6 cm (9% overall population), risk of ischaemic stroke was lower in rivaroxaban vs. aspirin group (1.7 vs 6.5%/year).

 

Effectively Initiating and Maintaining Anticoagulation in Patients With Atrial Fibrillation: Lessons Learned From Research and Practice

Circulation

With availability of DOACs, authors have seen large increases in anticoagulation (AC) rates, but considerable gaps in guideline adherence remain among high-risk patients. Article shares practical strategies to address common barriers to initiating/maintaining AC in this group.

 

Oral anticoagulation among atrial fibrillation patients with anaemia: an observational cohort study

European Heart Journal

Observational cohort-study of 18,734 anaemic AF patients suggests treatment with oral anticoagulants increased rate of major bleeding and reduced time in therapeutic range with no reduction in risk of stroke/thromboembolism particularly among patients with moderate/severe anaemia.

 

Risk factors for thromboembolic and bleeding events in anticoagulated patients with atrial fibrillation: the prospective, multicentre observational PREvention oF thromboembolic events - European Registry in Atrial Fibrillation (PREFER in AF)

BMJ Open

Study of 5310 pts receiving a VKA and 3156 pts receiving a NOAC found that abnormal liver function, prior stroke or TIA, labile INR, therapy with antiplatelet or NSAIDs, heart failure and age ≥75 yrs were independently associated with thromboembolic and major bleeding events.

 

Direct oral anticoagulation and mortality in moderate to high-risk atrial fibrillation

Heart

Retrospective analysis of patients (n=11,314) with non-valvular atrial fibrillation reports DOAC therapy was associated with a significantly lower risk of death compared with no oral anticoagulation: 7.6% vs 11.1% per year respectively (HR=0.69, p<0.001).
