BACKGROUND: Recent studies suggest that reduced right ventricular function is an important predictor of outcome in patients with heart failure and preserved ejection fraction (HFpEF). Because affected patients suffer from a broad spectrum of non-cardiac co-morbidities, it remains unclear, whether they actually die from right heart failure (RHF) or as a consequence of other conditions. METHODS: Consecutive patients with a confirmed diagnosis of HFpEF were enrolled in this prospective registry...

BACKGROUND AND PURPOSE: Acute stroke patients with unknown time of symptom onset are ineligible for thrombolysis. The diffusion-weighted imaging and fluid-attenuated inversion recovery (FLAIR) mismatch is a reasonable predictor of stroke within 4.5 hours of symptom onset, and its clinical usefulness in selecting patients for thrombolysis is currently being investigated. The accuracy of the visual mismatch rating is moderate, and we hypothesized that the predictive value of stroke onset within 4...

BACKGROUND: It is currently unknown if premature atrial contractions (PACs) detected on the routine screening electrocardiogram are associated with an increased risk of ischemic stroke. METHODS: We examined the association between PACs and ischemic stroke in 22,975 (mean age 64 ± 9.2; 56% women; 40% black) participants from the Reasons for Geographic and Racial Differences in Stroke study. Participants who were free of stroke at baseline were included. PACs were detected from centrally read electrocardiograms at baseline...

Intravenous (IV) thrombolysis is the treatment in ischemic stroke, but only the minority of patients receive this medication. The primary objective of this study was to explore the reasons associated with the decision not to offer IV thrombolysis to stroke patients admitted to the Stroke Unit (SU). We conducted a retrospective analysis based on data collected from 876 consecutive stroke patients admitted to the SU <12 h of symptoms onset, treated or not with IV thrombolysis at the discretion of the treating neurologist...

Experimental stroke models producing clinically relevant functional deficits are often associated with high mortality. Because the mechanisms that underlie post-stroke mortality are largely unknown, results obtained using these models are often difficult to interpret, thereby limiting their translational potential. Given that specific forms of post-stroke care reduce mortality in patients, we hypothesized that inadequate food and water intake may underlie mortality following experimental stroke. C57BL/6 mice were subjected to 1 h of intraluminal filament middle cerebral artery occlusion...

BACKGROUND: The mechanisms behind the association of atrial fibrillation (AF) and dementia are unknown. We previously found a significantly increased risk of dementia in AF patients taking warfarin with a low percentage of time in therapeutic range. The purpose of this study was to determine the extent to which AF itself increases dementia risk, in addition to long-term anticoagulation exposure. METHODS AND RESULTS: A total of 10 537 patients anticoagulated with warfarin (target INR 2-3), managed by the Clinical Pharmacist Anticoagulation Service with no history of dementia were included...

BACKGROUND: Cardiovascular secondary preventive recommendations are often not reached. We investigated whether a nurse-led telephone-based follow-up could improve the implementation of a new guideline within a year after its release. METHODS: In February 2013, a new secondary preventive guideline for diabetic patients was released in the county of Jämtland, Sweden. It included a changed of the low-density lipoprotein cholesterol (LDL-C) target value from <2...

OBJECTIVES: Approximately 7% of patients examined with panoramic radiographs (PRs) for odontological reasons, and with incidental findings of carotid artery calcification (CAC), have significant (≥50%) carotid stenosis (SCS). The aim of this study was to determine if the radiographic appearance of CACs in PRs could be categorized such that we could improve the positive-predictive value (PPV) for SCS detection. METHODS: This cross-sectional study included 278 patients with CACs identified by PRs, 127 with SCS and 151 without SCS...

Esther S H Kim, Maya Serhal
Fibromuscular dysplasia (FMD) is an arteriopathy of unknown etiology which has traditionally been associated with secondary hypertension; however, it has garnered increased attention in the cardiology field in the recent years because of its potential association with spontaneous coronary artery dissection. Cardiologists should be aware that FMD is a polyvascular disease which can affect any arterial bed and can result in morbid conditions such as chronic headaches, pulsatile tinnitus, stroke from cervical artery dissection, and renal infarction from renal artery dissection and has also been associated with increased prevalence of arterial aneurysm, including brain aneurysm...

Per Andersson, Magnus Löndahl
BACKGROUND: Atrial fibrillation (AF) affects about 3.2% of the adult population in the western world and incurs an annual stroke risk of 4.5%. The use of oral anticoagulant (OAC) drugs significantly reduces this risk. OAC drugs seem to be under-utilized, but little is known about why their use is restrained in routine clinical management. The aim of this study was to assess this issue and, from these data, to estimate the proportion of patients with AF in a general population who were eligible for treatment with OAC drugs...

OBJECTIVES: Young adults with ischemic stroke may present late to medical care, but the reasons for these delays are unknown. We sought to identify factors that predict delay in presentation. METHODS: We performed a retrospective cohort study of adults aged 18-50 admitted to a single academic medical center between 2007 and 2012. RESULTS: Eighty six of 141 (61%) young adults with ischemic stroke presented at the health center more than 4.5 h after stroke onset...

Stroke is the most common neurological cause of morbidity and mortality in industrialized countries, afflicting 15 million people every year. The numbers are expected to increase, mostly due to aging populations. One in five stroke patients dies, and one in three are left with permanent disabilities. Although some acute phase therapies such as intravenous recombinant tissue plasminogen activator (rt-PA) andendovascular treatment have been shown to improve ischemic stroke outcome, these therapies are available only for a small proportion of patients...

BACKGROUND AND PURPOSE: Antithrombotic medications are effective for ischemic stroke prevention, but stoppage of these medications is associated with an increased risk of thromboembolism. The frequency of antithrombotic withdrawal in the general population is unknown. METHODS: We conducted a random phone sample of 2036 households in the Greater Cincinnati metropolitan area, representative of the stroke population by age, sex, and race, to determine the frequency of antithrombotic medication use and stoppage by physicians for medically indicated procedures...

OBJECTIVES: The National Quality Forum recently endorsed a performance measure for time to intravenous thrombolytic therapy which allows exclusions for circumstances in which fast alteplase treatment may not be possible. However, the frequency and impact of unavoidable patient reasons for long door-to-needle time (DNT), such as need for medical stabilization, are largely unknown in clinical practice. As part of the Hurry Acute Stroke Treatment and Evaluation-2 (HASTE-2) project, we sought to identify patient and systems reasons associated with longer DNT...

BACKGROUND: Tracheostomy is a common procedure in long-term ventilated critical care patients and frequently necessary in those with severe stroke. The optimal timing for tracheostomy is still unknown, and it is controversial whether early tracheostomy impacts upon functional outcome. METHOD: The Stroke-related Early Tracheostomy vs. Prolonged Orotracheal Intubation in Neurocritical care Trial 2 (SETPOINT2) is a multicentre, prospective, randomized, open-blinded endpoint (PROBE-design) trial...

Jessica E Owen, Glenda M Bishop, Stephen R Robinson
Hemin is a breakdown product of the blood protein, hemoglobin and is responsible for much of the secondary damage caused following a hemorrhagic stroke. Hemin is toxic to cultured astrocytes and it is thought that this toxicity is due to iron that is liberated when hemin is degraded. However, free iron applied to astrocytes is not toxic and the reason for this discrepancy is unknown. The present study exposed primary astrocyte cultures from neonatal mice to hemin-iron (25 µM hemin) or non-hemin iron (25 µM ferric ammonium citrate; FAC) for 12 or 24 h...
