Critical Issues and Recent Advances in Anticoagulant Therapy: A Review

Angelika Batta, Bhupinder S Kalra, Raj KhirasariaNeurology India 2019 67(5):1200-1212 As the population is aging, clinicians are coming across more patients with atrial fibrillation and venous thromboembolism requiring anticoagulation to prevent stroke and systemic embolisms. Due to a high prevalence and unfavorable consequences, managing thromboembolic diseases have become areas of clinical concern. Traditional anticoagulants like heparin, low molecular weight heparin and warfarin have been used for the prevention and treatment of venous and arterial thromboses. But, issues of bleeding, parenteral route of administration, or the need for frequent monitoring due to variability in response respectively limit their use. The article gives an overview of coagulation along with existing therapy available for anticoagulation and to present an update on utility and recent advances of new oral anticoagulants (NOACs) beginning from their nomenclature, advantages, disadvantages, precautions and contraindications compared with those of vitamin K antagonists (VKAs) based on a large number of recent studies and clinical trials.

Conclusions: A substantial portion of hospitalized AF patients did not receive any AC therapy, particularly those patients with an AF diagnosis in the second position on hospital records. The predictors of inpatient AC treatment that were identified may be helpful in the clinical decision-making process for patients who are hospitalized with AF.

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]

Abstract BACKGROUND:  The effects of anticoagulants at extremes of body weight (BW) are not well described. The aim of this study was to analyze the pharmacokinetics/pharmacodynamics and clinical outcomes in patients randomized to warfarin, higher dose edoxaban (HDER), and lower dose edoxaban (LDER) regimens at extremes of BW in ENGAGE AF-TIMI 48. METHODS AND RESULTS:  We analyzed three BW groups: low BW (LBW: 95th percentile, ≥120 kg, N = 1,093). In the warfarin arm, LBW patients had higher rates of stroke/systemic embolism (SSE: 6.5 vs. 4.7 in MBW vs. 1.6% in HBW, P trend

AbstractPurpose of ReviewIn patients with atrial fibrillation who are unable to take novel oral anticoagulants for stroke prophylaxis due to bleeding risk or other contraindications, left atrial appendage (LAA) occlusion and exclusion devices have shown benefit. In this review, we highlight the risks and benefits associated with LAA removal.Recent FindingsLAA, once considered a vestigial organ, has been shown to have physiological, anatomical, and arrhythmogenic properties. Device-related complications such as pericardial effusion, device embolization, device-related thrombus, while uncommon, are still present. With increa...

ConclusionAcross geriatric subgroups, apixaban was consistently associated with the most favourable benefit-risk profile and should therefore be preferred in geriatric patients with AF. However, research gaps on the impact of increased falling risk, frailty and baseline dementia were identified, requiring careful consideration while awaiting more results.
