Efficacy and safety of apixaban compared with warfarin according to age for stroke prevention in atrial fibrillation: observations from the ARISTOTLE trial

Aims The risk of stroke in patients with atrial fibrillation (AF) increases with age. In the ARISTOTLE trial, apixaban when compared with warfarin reduced the rate of stroke, death, and bleeding. We evaluated these outcomes in relation to patient age. Methods and results A total of 18 201 patients with AF and a raised risk of stroke were randomized to warfarin or apixaban 5 mg b.d. with dose reduction to 2.5 mg b.d. or placebo in 831 patients with ≥2 of the following criteria: age ≥80 years, body weight ≤60 kg, or creatinine ≥133 μmol/L. We used Cox models to compare outcomes in relation to patient age during 1.8 years median follow-up. Of the trial population, 30% were

This study aimed to compare the long-term outcome of triple antithrombotic therapy (TAT) with that of dual antiplatelet therapy (DAPT) after AMI. This was a nationwide, propensity score-matched, case –control study of 186,112 first AMI patients, of whom 2,825 received TAT comprising aspirin, clopidogrel, and warfarin. Propensity score matching in a ratio of 1:4 by age, sex, comorbidities, and treatment was adopted, Finally, 2,813 AMI patients and 11,252 matched controls that were administered TAT and DAPT (aspirin and clopidogrel), respectively, were included in our analysis. The 12-year overall survival rate did not...

CONCLUSION:  During the open-label extension, annual rates of stroke or systemic embolism, hemorrhagic stroke, and major bleeding remained as low as those observed during apixaban treatment in AVERROES. These data support the long-term efficacy and safety of apixaban in patients with atrial fibrillation. PMID: 33011964 [PubMed - as supplied by publisher]

ConclusionIn NVAF patients of all ages initiating either apixaban or warfarin for stroke prevention in the Sentinel System, apixaban was associated with a decreased risk of GI bleeding, ICH, and ischemic stroke compared with warfarin. Among patients less than 65  years of age, apixaban use was associated with a decreased risk of GI bleeding and ischemic stroke.

ConclusionsOur real-life data study suggests that secondary stroke prevention with DOACs is as effective and safe as primary prevention, both in standard and reduced doses, in a typical group of patients who are older than patients included in RCTs.

AbstractBackgroundLiver disease is associated with increased bleeding risk. The efficacy and safety of direct oral anticoagulants (DOACs) is a subject of contention in atrial fibrillation (AF) patients with liver disease.MethodsElectronic databases (PubMed, Embase, and Cochrane Library) were searched to retrieve studies on the efficacy and safety of DOACs versus warfarin in AF patients with liver disease from January 1980 to April 2020. A meta-analysis was conducted using a random-effects model.ResultsSix studies involving 41,859 patients were included. Compared with warfarin, DOACs demonstrated significant reduction in is...

CONCLUSIONS: Significant seasonal variations were observed for IS, ECH, and ICH events in AF patients, and were consistently the highest in winter. A small peak of ECH was observed in summer, which seemed, in part, to be related to increased DOAC use. PMID: 32863288 [PubMed - as supplied by publisher]
