BACKGROUND: Cerebral microbleeds are a potential neuroimaging biomarker of cerebral small vessel diseases that are prone to intracranial bleeding. We aimed to determine whether presence of cerebral microbleeds can identify patients at high risk of symptomatic intracranial haemorrhage when anticoagulated for atrial fibrillation after recent ischaemic stroke or transient ischaemic attack. METHODS: Our observational, multicentre, prospective inception cohort study recruited adults aged 18 years or older from 79 hospitals in the UK and one in the Netherlands with atrial fibrillation and recent acute ischaemic stroke or transient ischaemic attack, treated with a vitamin K antagonist or direct oral anticoagulant, and followed up for 24 months using general practitioner and patient postal questionnaires, telephone interviews, hospital visits, and National Health Service digital data on hospital admissions or death...

INTRODUCTION: Atrial fibrillation might increase the risk of dementia. We aim to test the hypothesis that dementia could reclassify the actual risk of stroke and death predicted by the CHA2DS2-VASc in patients with atrial fibrillation (AF). METHODS: A prospective study performed in a specific health care area. RESULTS: From our health care area (n = 348,985), throughout 2013, AF was codified in 7,990 (2.08%). Mean age was 76.83 ± 10.5, mean CHA2DS2-VASc = 3...

Recently, studies using late gadolinium enhancement (LGE) magnetic resonance imaging (MRI) to identify structural changes of atrial tissue have contributed significantly to understanding the pathophysiology and progression of atrial fibrillation (AF). Moreover, imaging of atrial fibrosis using MRI has evolved to be a tool to improve clinical outcome of AF ablation procedures by allowing a patient-specific individualized management approach. LGE-MRI has been shown to predict AF ablation outcome based on pre-procedural imaging to define the extent of atrial fibrosis...

BACKGROUND AND AIMS: Antioxidant status has been shown to be associated with cardiovascular events (CVEs). The aim of the study was to develop an assay measuring serum hydrogen peroxide (H2 O2 ) break-down activity (HBA) of healthy subjects (HS) and to validate it in a cohort of patients with atrial fibrillation (AF). METHODS: We developed the HBA assay in 121 HS and validated it in 842 AF patients. The occurrence of CVEs was registered and correlated with HBA in AF during a median follow-up of 30...

BACKGROUND: Several studies have compared the cost effectiveness of non-vitamin K antagonist oral anticoagulants (NOACs) and warfarin using results from clinical trials evaluating NOACs. However, the time in therapeutic range (TTR) of warfarin groups ranged across clinical trials, and all were below the therapeutic goal of 70%. We compared the cost effectiveness of edoxaban 60 mg, apixaban 5 mg, dabigatran 150 mg, dabigatran 110 mg, rivaroxaban 20 mg, and well-managed warfarin with a TTR of 70% in preventing stroke among patients with atrial fibrillation at high risk of bleeding...

BACKGROUND: Aortic valve calcification patterns were associated with short- and long-term outcomes in previous small observational datasets of patients undergoing transcatheter aortic valve implantation (TAVI). The specific impact of multi detector-row computed tomography (MDCT) findings on outcomes in women has not been reported. We sought to describe the associations between MDCT characteristics and clinical outcomes in a registry of 547 women undergoing TAVI. METHODS: WIN-TAVI is the first all-female registry to study the safety and effectiveness of TAVI in women (n = 1019)...

Atrial fibrillation (AF) and cancer are common disorders in the general population but there are few studies in patients with both diseases. More specifically, there are scarce data on AF in patients with non-Hodgkin lymphoma (NHL). We assessed the incidence, predictive factors, management, and survival impact of AF in a cohort of patients with NHL from a single institution between 2002 and 2016 (n = 747). Twenty-three patients were diagnosed with AF before and 40 after the diagnosis of NHL (of the later, 16 were secondary to an extracardiac comorbidity and 24 unrelated to any triggering event [primary AF])...

BACKGROUND:  Stroke risk in atrial fibrillation (AF) is often assessed at initial presentation, and risk stratification performed as a 'one off'. In validation studies of risk prediction, baseline values are often used to 'predict' events that occur many years later. Many clinical variables have 'dynamic' changes over time, as the patient is followed up. These dynamic changes in risk factors may increase the CHA2 DS2 -VASc score, stroke risk category and absolute ischaemic stroke rate...

BACKGROUND: Atrial fibrillation (AF) is an identified risk factor for ischemic strokes (IS). AF causes a loss in atrial contractile function that favors the formation of thrombi, and thus increases the risk of stroke. Also, AF produces highly irregular and complex temporal dynamics in ventricular response RR intervals. Thus, it is hypothesized that the analysis of RR dynamics could provide predictors for IS. However, these complex and nonlinear dynamics call for the use of advanced multiscale nonlinear signal processing tools...

BACKGROUND AND PURPOSE: Patients with stroke can experience neurological deterioration in the prehospital setting. We evaluated patients with stroke to determine factors associated with prehospital neurological deterioration (PND). METHODS: Among the Greater Cincinnati/Northern Kentucky region (population ~1.3 million), we screened all 15 local hospitals' admissions from 2010 for acute stroke and included patients aged ≥20. The GCS was compared between emergency medical services (EMS) arrival and hospital arrival, with decrease ≥2 points considered PND...

INTRODUCTION: Ischemic stroke is a potential perioperative complication after an open heart surgery (OHS). Whether a carotid stenosis or occlusion is associated with an increased risk of perioperative stroke in patients or just a risk factor has been a concern of intense debate in the literature. METHODS: We retrospectively analyzed patients submitted to OHS between January and December2016 with known asymptomatic carotid disease. The data from 85 consecutive patients undergoing coronary artery bypass grafting, valve replacement, or both was collected...

REVIEW
Farhan Shahid, Daniele Pastori, Francesco Violi, Gregory Y H Lip
Atrial fibrillation (AF) is associated with a 5-fold increase in the risk of ischemic stroke, and AF-related stroke patients have a higher mortality and greater morbidity than patients with non-AF related stroke. AF and vascular disease share a close relationship, with the concomitant presence of both disease states leading to a dramatic rise in future cardiovascular events. Indeed, the presence of peripheral artery disease independently predicts stroke in patients with AF. Myocardial infarction (MI) is another well-established risk factor for the development of AF; however, the role of pre-existing AF in MI is less well evidenced, with recent studies showing that this population more frequently develops coronary ischaemic events and has a higher risk of mortality than sinus rhythm patients...

BACKGROUND: Heart failure and atrial fibrillation share common mechanisms that may contribute to hypercoagulability and thrombotic risk. Elevated von Willebrand factor (vWF) concentration has been associated with increased risk of thromboembolism and cardiovascular events. AIM: To investigate whether increased vWF plasma concentration predicts occurrence of a composite endpoint (all-cause death and stroke) in patients with non-valvular atrial fibrillation (NVAF)...

BACKGROUND: Fever after stroke is common, and often caused by infections. In the current study, we aimed to test the hypothesis that pneumonia, urinary tract infection and all-cause fever (thought to include at least some proportion of endogenous fever) have different predicting factors, since they differ regarding etiology. METHODS: PubMed was searched systematically for articles describing predictors for post-stroke pneumonia, urinary tract infection and all-cause fever...

BACKGROUND: Increased supratentorial white matter hyperintensities volume (S-WMHV) has been reported as a predictor of worse outcome in acute ischemic stroke (AIS) patients. However, few studies focus on less common locations such as brainstem-white matter hyperintensities (B-WMH), and their relationship with S-WMHV. This study aimed to examine whether B-WMH affects clinical outcome after AIS or transient ischemic attack (TIA). METHODS: Based on MRI evidence, B-WMH was evaluated in 313 prospectively identified patients with AIS/TIA and registered as absent or present...

BACKGROUND: Left atrial (LA) volume is a predictor of outcome in hypertension. It is unclear whether or not this effect depends on coexisting target organ damage (TOD). PURPOSE: To investigate whether LA volume predicts outcome independently of TOD [left ventricular (LV) hypertrophy (LVH) and/or carotid plaque] in a registry of hypertensive treated patients. METHODS: From the Campania Salute Network registry, we selected 5844 young adult hypertensive patients <65 years old (mean age 50 ± 9 years, 41% women, 8% diabetic) without prevalent CV or valvular heart disease more than mild, with normal LV ejection fraction, stage III or less CKD and available follow-up...

Although current guidelines advocate using the CHA2 DS2 -VASc score to assess the risk of stroke in patients with atrial fibrillation (AF), compared with transesophageal echocardiography (TEE), its ability to predict left atrial appendage thrombus (LAAT) is limited. We studied 3,324 consecutive patients with sustained AF from our prospective registry of patients who underwent first-time TEE-guided electrical cardioversion (ECV) from May 2000 through March 2012. The association of CHA2 DS2 -VASc score or TEE risk factors with the occurrence of LAAT was analyzed...
