The aim of this study was to analyze the safety and efficacy of left atrial appendage occlusion (LAAO) as secondary prevention in patients with nonvalvular atrial fibrillation who have experienced a stroke/transient ischemic attack despite OAC treatment.MethodsWe analyzed data from the Amplatzer Cardiac Plug multicenter registry on 1047 consecutive patients with nonvalvular atrial fibrillation undergoing LAAO. Patientes with previous stroke on OAC therapy as indication for LAAO were identified and compared with patients with other indications.ResultsA total of 115 patients (11%) with RS were identified. The CHA2DS2-VASc and the HAS-BLED score were significantly higher in the RS group (respectively 5.5 ± 1....

Conclusions: Changing national guidelines with discard of contraindications for anticoagulation and the introduction of DOACs led to a broader recommendation of oral anticoagulation. However, both, new guidelines and DOACs, were not found to be associated with an increasing percentage of patients discharged from our hospital already on recommended anticoagulant prevention. This might be explained by the decreasing length of hospital stay during the study period and a missing evidence of early bleeding risk of DOACs in patients with acute brain infarction. Evidence-based data to close this therapeutic gap are needed.Cerebrovasc Dis

Purpose of review Direct oral anticoagulants (DOACs) are variably eliminated by the kidneys rendering their use potentially problematic in patients with chronic kidney disease (CKD) or necessitating appropriate dose adjustment. Recent findings Both observational and limited randomized trial data for DOACs compared with no treatment or with warfarin for patients with atrial fibrillation on maintenance dialysis were recently published. In a randomized trial in patients on hemodialysis, there was no significant difference in vascular calcification between patients who received rivaroxaban with or without vitamin K2 or vi...

Conclusions: Differences in study populations can and should be considered quantitatively to ensure results are relevant to populations of interest, particularly when comparing trial with nonexperimental findings. See video abstract: http://links.lww.com/EDE/B703.

Conclusion LAAO is an efficient and safe option for the prevention of cardioembolic stroke in patients with NVAF, high thromboembolic risk and contraindication to OAC, particularly in patients with previous intracranial bleeding.

Conclusion: Although we found that OAC use was effective and recommended for patients with AF, advanced kidney disease is still an independent risk factor for IS/SE, even in patients taking OAC. Physicians should be aware of this risk and strictly control modifiable risk factors, regardless of OAC use.Am J Nephrol

Abstract BACKGROUND: Adjunctive use of oral anticoagulant (OAC) and antiplatelet therapy (APT) in patients with stable coronary artery disease (CAD) and nonvalvular atrial fibrillation (AF) is a challenge of daily practice. METHODS: A comprehensive literature search of databases was performed to identify studies comparing the safety and efficacy of OAC monotherapy and combined therapy (OAC plus single (S) APT). Events including major adverse cardiovascular events (MACE), all-cause mortality, stroke and major bleeding were analyzed. RESULTS: Seven articles comprising 11,070 subjects were identified. Combi...

AbstractTriple anti-thrombotic therapy combining oral anticoagulation and dual anti-platelet therapy following percutaneous coronary intervention in patients with atrial fibrillation was considered as standard and recommended by guidelines. While bleeding risk is considerable with that approach, data for efficacy are scare. Several trials assessed the possibility of reducing anti-thrombotic treatment by mainly shortening the exposure to acetylsalicylic acid. Dropping one of the anti-platelet components might increase the risk of stent thrombosis, myocardial infarction or stroke. Despite that fear, the recent trials ’...

AbstractAimsPatients with concomitant atrial fibrillation (AF) and reduced left ventricular ejection fraction (LVEF) have poor prognosis. Outcomes of novel oral anticoagulant (NOAC) in elderly AF patients with normal, mid ‐range, and reduced LVEF were investigated.Methods and resultsData were retrieved from Chang Gung Research Database during 2010 –2017 for patients with AF. We excluded patients with venous thromboembolism within 6 months, total knee/hip replacement and heart valve replacement within 6 months, end‐stage renal disease, stroke/systemic embolism (SE)/death within 7 days, age

Authors: Deltour S, Pautas E Abstract Primary and secondary prevention of stroke is often a challenge in elderly patients due to the increase in both thrombotic and hemorrhagic risks with age. In some cases, there is sufficient data in the elderly population to allow recommendations or anticoagulation decisions to be made, such as for the indication of anticoagulation to prevent stroke related to atrial fibrillation (AF) or the choice of oral anticoagulant therapy in this situation. In other situations, the less robust data leave some questions; this is the case for the delay to initiate an oral anticoagulant thera...
