Antithrombotic selection and risk factor management in ischemic stroke and transient ischemic attack
OBJECTIVES This investigation was conducted to test the value of Neutrophil Lymphocyte Ratio (NLR), which has been shown in some recent studies to be a prognostically important and an easy-to-measure inflammatory marker, in patients presenting to Emergency Service with stroke (ischemic and hemorrhagic) and transient ischemic attack. MATERIALS AND METHODS A total of 868 patients were enrolled,...
BACKGROUND AND PURPOSE Cerebrovascular disease can complicate head and neck radiotherapy and result in transient ischemic attack and ischemic stroke. Although the incidence of radiation vasculopathy is predicted to rise with improvements in median cancer survival, the pathogenesis, natural history, and management of the disease are ill defined. METHODS We examined studies on the epidemiology,...
BACKGROUND AND PURPOSE Predictive instruments based on clinical features for early stroke risk after transient ischemic attack suffer from limited specificity. We sought to combine imaging and clinical features to improve predictions for 7-day stroke risk after transient ischemic attack. METHODS We studied 601 consecutive patients with transient ischemic attack who had MRI within 24 hours of ...
BACKGROUND AND PURPOSE Stroke symptoms in the absence of recognized stroke are common, but potential associated dysfunctions have not been described. METHODS We assessed quality-of-life measures using the Physical and Mental Component Summary scores of the Short Form 12 (PCS-12 and MCS-12) in the REasons for Geographic And Racial Differences in Stroke (REGARDS) cohort. Differences in mean PCS...
BACKGROUND AND PURPOSE White matter changes (WMC) are a common finding on brain imaging and are associated with an increased risk of ischemic stroke. They are most frequent in small vessel stroke; however, in the absence of comparisons with normal controls, it is uncertain whether WMC are also more frequent than expected in other stroke subtypes. Therefore, we compared WMC in pathogenic subtype...
BACKGROUND Soluble lectin-like oxidized low-density lipoprotein receptor-1 (sLOX-1) has been shown to be increased in patients with acute ischemic stroke. Here, we evaluated plasma sLOX-1 levels and vascular carotid plaque LOX-1 (ie, OLR1) gene expression in patients with ischemic stroke and transient ischemic attack (TIA) with particular focus on their relation to time since symptom onset. M...
BACKGROUND AND PURPOSE Patients with transient ischemic attack require carotid imaging to diagnose carotid stenosis. The differing sensitivity/specificity and availability of carotid imaging methods have created uncertainty over which noninvasive method is best and whether intra-arterial angiography is still required. We evaluated the influence of carotid imaging methods on secondary stroke pre...
Disorders of breathing during sleep are defined as cessation or reduction of air flow thorough the upper airway, accompanied by a decrease of oxygen saturation. The results of many studies underline the association between sleep-disordered breathing (SDB) and cerebrovascular disorders. SDB, mostly obstructive sleep apnea syndrome (OSAS), is believed to be an independent risk factor of stroke an...
