XANTUS: rationale and design of a noninterventional study of rivaroxaban for the prevention of stroke in patients with atrial fibrillation.

Abstract: Atrial fibrillation (AF) is associated with a fivefold increase in the risk of stroke. The Phase III ROCKET AF (Rivaroxaban Once-Daily Oral Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation) trial showed that rivaroxaban, an oral, direct Factor Xa inhibitor, was noninferior to warfarin for the reduction of stroke or systemic embolism in patients with AF. Compared with warfarin, rivaroxaban significantly reduced rates of intracranial and fatal hemorrhages, although not rates of bleeding overall. XANTUS (Xarelto(®) for Prevention of Stroke in Patients with Atrial Fibrillation) is a prospective, international, observational, postauthorization, noninterventional study designed to collect safety and efficacy data on the use of rivaroxaban for stroke prevention in AF in routine clinical practice. The key goal is to determine whether the safety profile of rivaroxaban established in ROCKET AF is also observed in routine clinical practice. XANTUS is designed as a single-arm cohort study to minimize selection bias, and will enroll approximately 6,000 patients (mostly from Europe) with nonvalvular AF prescribed rivaroxaban, irrespective of their level of stroke risk. Overall duration of follow-up will be 1 year; the first patient was enrolled in June 2012. Similar studies (XANTUS-EL [Xarelto(®) for Prevention of Stroke in Patients with Nonvalvular Atrial Fibrillation, Eastern Europe, Middle East, Africa and Latin America] and XANAP [Xarelto(®) for Prevention of Stroke in Patients with Atrial Fibrillation in Asia-Pacific]) are ongoing in Latin America and Asia-Pacific. Data from these studies will supplement those from ROCKET AF and provide practical information concerning the use of rivaroxaban for stroke prevention in AF.

Predictable and Less Predictable Unwanted Cardiac Drugs Effects: Individual Pre-Disposition and Transient Precipitating Factors

Abstract: In addition to their therapeutic effect, all drugs have unwanted effects For the purpose of this MiniReview, unwanted drug effects will be discussed as either predictable, dose-dependent effects, or as less predictable events which only occur in patients pre-disposed to unwanted drug reactions when confronted with specific situations While clinicians have long been using biomarkers to identify patients prone to less predictable unwanted drug effects, emerging data clearly suggest that such effects are often a consequence of interactions between drug effects, drug metabolism, an individual, at times genetically conferred pre-disposition to the interaction, and transient pre-disposing factors This paper describes general principles of predictable and less predictable unwanted drug effects and discusses the complex interplay of genetic and acquired pre-disposing and precipitating factors for such effects using the example of ventricular pro-dysrhythmia The latter, an important unwanted effect of many drugs, is a common yet not fully understood less predictable cardiac drug effect Understanding the mechanisms of ventricular pro-dysrhythmia may allow to predict this unwanted drug effect better, and to identify novel markers for such events in the future

Brain MRI to personalise atrial fibrillation therapy: current evidence and perspectives

Abstract: Advances in the access to and in the performance of brain MRI have led to an increased detection of asymptomatic abnormalities in the brain of patients with cardiovascular diseases. These may have prognostic impact and could influence management in the future. In this review, we summarise the main findings of brain MRI in patients with atrial fibrillation (AF) and explore the available evidence to better quantify the risk for intracerebral haemorrhage and (recurrent) ischaemic stroke based on brain MRI findings. Treatment decisions in the majority of patients with AF should still be based on data from established validated risk scores and large randomised trials. Whether brain MRI has the potential to improve the personalised management of patients with AF by guiding the risk and benefit assessment of stroke prevention by oral anticoagulants remains to be established in large prospective studies using standardised brain MRI. However, even today, brain MRI may help to identify subsets of patients with AF at increased risk for (recurrent) intracerebral bleeding. Although present knowledge and MRI-associated costs do not support routine use of brain MRI in asymptomatic patients with AF, as more data emerge MRI may become an increasingly useful way to stratify patients with AF and individualise their treatment.

Characteristics and outcomes of atrial fibrillation patients with or without specific symptoms – results from the PREFER in AF registry

Abstract: Background Atrial fibrillation (AF) is a common condition that is a major cause of stroke. A significant proportion of patients with AF are not classically symptomatic at diagnosis or soon after diagnosis. There is little information comparing their characteristics, treatment, and outcomes of patients with symptoms, which predominate in clinical trials to those without. Methods We analysed data from the Prevention of Thromboembolic Events – European Registry in Atrial Fibrillation (PREFER in AF). This was a prospective, real-world registry with a 12-month follow-up that included AF patients aged 18 years and over. Patients were divided into those with and without AF symptoms using the European Heart Rhythm Association (EHRA) score (category I vs. categories II – IV). Results Of the 6,196 patients (mean age 72 years) with EHRA scores available, 501 (8.1%) were asymptomatic. A lower proportion of asymptomatic patients was female (22.8% vs. 41.2%), with less noted to have heart failure and coronary artery disease (p<0.01 for all). There were no differences in terms of the prevalence of diabetes, obesity, or prior stroke. Asymptomatic patients had a lower CHA2DS2-VASc score (2.9±1.7 vs. 3.4±1.8; p<0.01) and HAS-BLED score (1.8±1.1 vs. 2.1±1.2; p<0.01). During the one-year follow-up, adverse events occurred at similar frequencies in asymptomatic and symptomatic patients (1.6% vs. 0.8% for ischemic stroke; p=0.061; 1.4% vs. 1.3% for transient ischaemic attack; p=0.840). Patients with higher CHA2DS2-VASc and HAS-BLED scores experienced more events, independent of symptoms. Antithrombotic therapy was comparable for both groups at baseline and at follow-up. Conclusions The similar clinical characteristics and frequency of adverse events between asymptomatic and symptomatic AF patients revives the question of whether screening programmes to detect people with asymptomatic AF are worthwhile, particularly in those aged 65 and over potentially likely to have clinical and economic benefits from anticoagulants. This evidence may be informative if clinicians may not be comfortable participating in future clinical trials, leaving asymptomatic patients with AF and high stroke risk without anticoagulation.
