Frequency and Determinants of Adherence to Oral Anticoagulants in Stroke Patients with Atrial Fibrillation in Clinical Practice
Background: Vitamin K antagonists (VKAs) and non-VKA oral anticoagulants (NOACs) are beneficial in patients with stroke and atrial fibrillation (AF). However, little is known about frequency and determinants of adherence to NOACs/VKAs in clinical practice.Methods: This is a single-center explorative study from the Novel Oral Anticoagulants in Stroke Patients (NOACISP)-LONGTERM registry. We included consecutive AF-stroke patients treated with NOACs/VKAs and followed up for 3-24 months. Adherence was assessed at follow-up using structured interviews and quantified as the proportion of prescribed doses taken (PDT). Outcome me...

Vitamin D deficiency is associated with acute ischemic stroke, C-reactive protein, and short-term outcome
AbstractThe aim of this study was to investigate whether vitamin D deficiency (VDD) is associated with acute ischemic stroke, inflammatory markers, and short-term outcome. 168 acute ischemic stroke patients and 118 controls were included. The modified Rankin Scale (mRS) was applied up to 8  h of admission (baseline) and after three-months follow-up, and blood samples were obtained up to 24 h of admission to evaluate serum levels of 25-hydroxivitamin D [25(OH)D] and inflammatory markers. Vitamin D levels classified the individuals in sufficient (VDS ≥ 30.0 ng/mL), insufficient (VDI 20.0–29.9 ng/mL), and deficien...

Is There an Obesity Paradox for Outcomes in Atrial Fibrillation? Clinical Sciences
Conclusions—There may be an obesity paradox in atrial fibrillation patients, particularly for all-cause and cardiovascular death outcomes. An obesity paradox was also evident for stroke/systemic embolic event outcome in NOAC trials, with a treatment effect favoring NOACs over warfarin for both efficacy and safety that was significant only for normal weight patients.

Intravenous thrombolysis for acute ischemic stroke: a bridge between two centuries.
Authors: Tsivgoulis G, Kargiotis O, Alexandrov A Abstract INTRODUCTION: Intravenous tissue-plasminogen activator (tPA) remains the only approved systemic reperfusion therapy suitable for most patients presenting timely with acute ischemic stroke. Accumulating real-word experience for over 20 years regarding tPA safety and effectiveness lead to re-appraisal of original contraindications for intravenous thrombolysis (IVT). Areas covered: This narrative review focuses on fast yet appropriate selection of patients for safe administration of tPA per recently expanded indications. Novel strategies for rapid patient assessme...

Influence of oral anticoagulation on stroke severity and outcomes: A propensity score matching case-control study
Oral anticoagulants (OAC) such as vitamin K antagonists (VKA) and direct-acting OACs (DOAC) remain the mainstay for prevention of cardioembolic stroke. The influence of previous OAC treatment on stroke severity and outcomes is not well stablished. We compared patients with incident cardioembolic strokes according to pre-stroke treatment.

Impact of 25-Hydroxyvitamin D on the Prognosis of Acute Ischemic Stroke: Machine Learning Approach
Conclusions: 25-hydroxyvitamin D deficiency was highly prevalent in Korea and low 25-hydroxyvitamin D level was associated with poor outcome in patients with AIS. The machine learning approach of extreme gradient boosting was also useful to assess stroke prognosis along with logistic regression analysis.

C-Reactive Protein Predicts Hematoma Growth in Intracerebral Hemorrhage Clinical Sciences
Conclusions— CRP>10 mg/L is independently predictive of EHG and ENW, both of which are associated with increased mortality. Inflammation may be important in contributing to EHG and warrants further investigation.

Estimating the Quantitative Demand of NOAC Antidote Doses on Stroke Units
Background: The first specific antidote for non-vitamin K antagonist oral anticoagulants (NOAC) has recently been approved. NOAC antidotes will allow specific treatment for 2 hitherto problematic patient groups: patients with oral anticoagulant therapy (OAT)-associated intracerebral hemorrhage (ICH) and maybe also thrombolysis candidates presenting on oral anticoagulation (OAT). We aimed to estimate the frequency of these events and hence the quantitative demand of antidote doses on a stroke unit. Methods: We extracted data of patients with acute ischemic stroke and ICH (

New frontiers in anticoagulation: non vitamin-K oral anticoagulants in stroke prevention.
Authors: Arnao V, Riolo M, Tuttolomondo A, Pinto A, Fierro B, Aridon P Abstract INTRODUCTION: Non vitamin-K oral anticoagulants (NOACs) are direct and specific inhibitors of the coagulation factors IIa (dabigatran) and Xa (apixaban, rivaroxaban, edoxaban) which share many pharmacokinetic properties. However, indications are lacking regarding the use of NOACs during thrombolysis, surgery and bleeding events. Areas covered: In this paper, the authors retrospectively analyzed the relevant literature on the NOACs using the PubMed and Google Scholar databases. Expert Commentary: Although warfarin is effective in cardioembo...

Comparison of the cost-utility of direct oral anticoagulants for the prevention of stroke in patients with atrial fibrillation in Spain.
CONCLUSIONS: All three direct anticoagulants are cost-effective against acenocoumarol. Dabigatran is economically dominant over rivaroxaban and apixaban in the Spanish setting, as it is more effective and cheaper. PMID: 28272725 [PubMed - in process]

Personal View B vitamins in stroke prevention: time to reconsider
B vitamin therapy lowers plasma total homocysteine concentrations, and might be a beneficial intervention for stroke prevention; however, cyanocobalamin (a form of vitamin B12) can accelerate decline in renal function and increase the risk of cardiovascular events in patients with impaired renal function. Although early trials did not show benefit in reduction of stroke, these results might have been due to harm in participants with impaired renal function. In patients with diabetic nephropathy, cyanocobalamin is harmful, whereas B vitamins appear to reduce cardiovascular events in study participants with normal renal function.

Long-term antithrombotic treatment in intracranial hemorrhage survivors with atrial fibrillation
Conclusions: In observational studies, anticoagulation with VKA is associated with a lower rate of IS than APA or no-ATM without increasing ICH recurrence significantly. A randomized controlled trial is needed to determine the net clinical benefit of anticoagulation in ICH survivors with AF.
