Background. The role of genetic factors in the predisposition to develop ischemic stroke has been assessed by previous studies. The main goal of the current study was to determine any possible role of TNF-857C>T,TNFRSF1A36A>G, and TNFRSF1B676T>G polymorphisms in risk for stroke. Materials and Methods. One hundred seventy-three patients with first ever(More)
Knowledge acquisition techniques investigate ways to pick up information about the way that medical experts work and decide in order to resemble their behaviour and assist them in analysing a patient's condition. Available data can sometimes be complicated and by representing them in crisp or nominal values the diagnosis scheme loses in terms of(More)
A seasonal variation with an incidence peak during the colder period of the year, as well as a circadian distribution with a single peak of stroke onset in the morning hours are described in various countries. Cardioembolic stroke seems to be the most frequent stroke subtype among Greek patients. Atrial fibrillation is identified as the most frequent cause(More)
OBJECTIVE To compare the accuracy of a-priori and a-posteriori dietary patterns in the prediction of acute coronary syndrome (ACS) and ischemic stroke. This is actually the first study to employ state-of-the-art classification methods for this purpose. METHODS AND MATERIALS During 2009-2010, 1000 participants were enrolled; 250 consecutive patients with a(More)
BACKGROUND AND PURPOSE Isolated pontine strokes cause characteristic neurological syndromes and have a good short-term prognosis. The aim of this study was to examine the long-term survival, cumulative recurrence rate and clinical handicap of patients with isolated pontine infarcts of different aetiology. METHODS One hundred consecutive patients with an(More)
OBJECTIVE CHADS2 and CHA2DS2-VASc scores are used to assess stroke risk in patients with atrial fibrillation (AF). We investigated whether these scores are associated with stroke outcome in non-AF stroke patients. METHODS Consecutive patients with acute first-ever ischemic stroke but without AF were classified into subgroups according to prestroke CHADS2(More)
OBJECTIVE We aimed to investigate the association between leukoaraiosis and long-term risk of stroke recurrence adjusting for clinical scores developed and validated for the prediction of stroke risk, such as CHADS2 (congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, and stroke or TIA) and CHA2DS2-VASc (congestive heart failure,(More)
Impaired endothelium-dependent, flow-mediated dilatation of the brachial artery was observed in a 50-year-old premenopausal female non-smoker with idiopathic hemochromatosis. Endothelial dysfunction observed in this patient supports a relationship between body iron stores and early atherosclerotic process.
BACKGROUND Stroke comprises the leading cause of death in Greece, and more than 40% of the overall lifetime cost for stroke care, represents the acute phase hospitalization. The aim of the present study was to assess the resource utilization and estimate the costs for treatment of stroke patients in an Acute Stroke Unit (ASU). METHODS Patients with(More)
