Estimated prevalence of undiagnosed atrial fibrillation in the United States.

2017

Introduction As atrial fibrillation (AF) is often asymptomatic, it may remain undiagnosed until or even after development of complications, such as stroke. Consequently the observed prevalence of AF may underestimate total disease burden. Methods To estimate the prevalence of undiagnosed AF in the United States, we performed a retrospective cohort modeling study in working age (18-64) and elderly (≥65) people using commercial and Medicare administrative claims databases. We identified patients in years 2004-2010 with incident AF following an ischemic stroke. Using a back-calculation methodology, we estimated the prevalence of undiagnosed AF as the ratio of the number of post-stroke AF patie…

e-Health-based management of patients receiving oral anticoagulation therapy: results from the observational thrombEVAL study

2017

Essentials e-Health based health care by an expert centre may advance management of oral anticoagulation. Outcome of patients was compared between an e-health based coagulation service and regular care. Patients in the coagulation service cohort experienced a significantly better clinical outcome. Lower risk for adverse events was related to anticoagulation-specific and non-specific outcome. SummaryBackground Management of oral anticoagulation (OAC) therapy is essential to minimize adverse events in patients receiving vitamin K-antagonists (VKAs). Data on the effect of e-health-based anticoagulation management systems on the clinical outcome of OAC patients are limited. Objectives To compar…

Positive Predictive Value of French Hospitalization Discharge Codes for Stroke and Transient Ischemic Attack.

2015

<b><i>Background:</i></b> We aimed at measuring the positive predictive value (PPV) of data in the French Hospital Medical Information Database (FHD). <b><i>Summary:</i></b> This retrospective multicenter study included 31 hospitals from where 56 hospital stays were randomly selected among all hospitalizations for the years 2009 and 2010 with at least 1 principal diagnosis of stroke or transient ischemic attack (TIA). Three algorithms were evaluated. Algorithm 1 selected discharge abstracts with at least 1 principal diagnosis identified by one of the relevant International Classification of Diseases, 10th revision codes. Algorithm 2 selected s…

Ischemic stroke and migraine in childhood: coincidence or causal relation?

1999

Although migraine is an accepted cause of cerebral infarction in adults, this association is less well recognized in children. We present two children with migraine and cerebral infarction, which we regard as migrainous stroke, though neither patient fulfills all criteria of the International Headache Society for the diagnosis of migrainous infarction. Review of the literature concerning examples of migraine-associated stroke in childhood suggests that these criteria are too restrictive to comprise the majority of migrainous strokes, especially in this age group. (J Child Neurol 1999; 14:451-455).

Impact of completeness of ascertainment of minor stroke on stroke incidence: implications for ideal study methods.

2013

Background and Purpose— Reliable comparisons of stroke incidence are important. To determine the impact of systematic assessment of patients referred with transient ischemic attack on the measured incidence and severity of stroke, we compared 2 population-based studies. Methods— Patients with first-ever stroke ascertained during 2006 through 2010 from the Dijon Stroke Registry and the Oxford Vascular (OXVASC) Study were studied. Both studies comply with the criteria for ideal incidence studies, but the OXVASC Study also systematically assessed all patients referred with transient ischemic attack. Stroke severity was measured by the National Institutes of Health Stroke Scale. Results— Among…

Temporal trends in the premorbid use of preventive treatments in patients with acute ischemic cerebrovascular events and a history of vascular diseas…

2017

Although secondary prevention in patients with arterial vascular diseases has improved, a gap between recommendations and clinical practice may exist.We aimed to evaluate temporal trends in the premorbid use of preventive treatments in patients with ischemic cerebrovascular events (ICVE) and prior vascular disease.Patients with acute ICVE (ischemic stroke/TIA) were identified through the population-based stroke registry of Dijon, France (1985-2010). Only those with history of arterial vascular disease were included and were classified into four groups: patients with previous coronary artery disease only (CAD), previous peripheral artery disease only (PAD), previous ICVE only, and patients w…

Stroke care organization overcomes the deleterious ‘weekend effect’ on 1-month stroke mortality: a population-based study

2013

Background and purpose Suffering a stroke during the weekend is associated with a poorer prognosis. The impact of implementing a dedicated stroke care network in Dijon, France, in 2003 on 30-day mortality in strokes/transient ischaemic attacks (TIA) occurring during weekends/bank holidays was evaluated. Methods All cases of stroke and TIA from 1985 to 2010 were identified from a population-based registry, using multiple overlapping sources of information. Demographics and clinical data were recorded. Cox regression models were used to evaluate associations between day of onset (weekdays versus weekends/bank holidays) and 30-day all-cause mortality. Data were stratified according to time per…

Incidence and Clinical Impact of Recurrent Takotsubo Syndrome: Results From the GEIST Registry

2019

Background Current literature only reports variable information from single‐center studies on the recurrence rate, the complications, and the outcome of patients with Takotsubo syndrome ( TTS) experiencing recurrent TTS . Therefore, a detailed description of clinical characteristics, predictors, and the prognostic impact of patients with TTS and recurrences in a multicenter registry is needed. Methods and Results We analyzed 749 patients with TTS from 9 European centers being part of the international, multicenter GEIST (German Italian Stress Cardiomyopathy) Registry. Patients were divided into the recurrence group and the nonrecurrence group. The recurrence rate at a median follow‐up of 8…

Global, regional, and country-specific lifetime risks of stroke, 1990 and 2016

2018

Background: The lifetime risk of stroke has been calculated in a limited number of selected populations. We sought to estimate the lifetime risk of stroke at the regional, country, and global level using data from a comprehensive study of the prevalence of major diseases.Methods: We used the Global Burden of Disease (GBD) Study 2016 estimates of stroke incidence and the competing risks of death from any cause other than stroke to calculate the cumulative lifetime risks of first stroke, ischemic stroke, or hemorrhagic stroke among adults 25 years of age or older. Estimates of the lifetime risks in the years 1990 and 2016 were compared. Countries were categorized into quintiles of the sociode…
