Although the benefit of antithrombotic therapy for stroke prevention in atrial fibrillation (AF) is well recognized, its potential effect on stroke severity and outcome is less well established. Our objective was to examine the effect of preadmission antithrombotic therapy on stroke severity and outcome in patients with AF within a large comprehensive(More)
BACKGROUND In the setting of an acute stroke, anemia has the potential to worsen brain ischemia, however, the relationship between the entire range of hemoglobin to long-term outcome is not well understood. METHODS We examined the association between World Health Organization-defined admission anemia status (hemoglobin<13 in males, <12 g/dl in women) and(More)
BACKGROUND Chronic kidney disease (CKD) is associated with both a risk of adverse vascular outcome and a risk of bleeding. We have tested the hypothesis that in the setting of an acute intracerebral hemorrhage (ICH), CKD is associated with poor outcome and with larger hematoma volume. METHODS We examined the association between CKD and ICH characteristics(More)
BACKGROUND AND PURPOSE Coronary artery calcium is an independent predictor of all-cause mortality. We sought to examine the determinants of intracranial cerebral artery calcification (CAC) and its association with long-term outcome in a large prospective cohort of stroke patients. METHODS Consecutive patients hospitalized because of acute stroke(More)
BACKGROUND AND PURPOSE Chronic kidney disease (CKD) is increasingly recognized as an independent risk factor for cardiovascular disease and stroke. Our aim was to examine the association between estimated glomerular filtration rate (GFR) and stroke outcome and to assess whether CKD and its severity affect stroke outcome in a large cohort of unselected(More)
BACKGROUND Congestive heart failure is associated with cognitive impairment, particularly of attentional skills. We assessed, in a hypothesis-generating study, the effect of an exercise training program on cognitive functions among patients with severe congestive heart failure. METHODS Patients with severe congestive heart failure (n=20; New York Heart(More)
BACKGROUND Calcium concentrations in serum are maintained within an exquisitely narrow range. Our aim was to examine the association between serum calcium and albumin-adjusted calcium (calcium(adj)) levels and stroke outcome in a cohort of unselected patients with acute stroke. METHODS Consecutive patients hospitalized due to acute stroke (ischemic or(More)
BACKGROUND Programmed ventricular stimulation is commonly used to guide therapy in post-myocardial infarction patients with sustained monomorphic ventricular tachycardia (VT) or ventricular fibrillation (VF). In patients with valvular heart disease presenting with spontaneous VT, VF, or syncope, the usefulness of this technique is still unclear. The aim of(More)
BACKGROUND Multiple case series, mostly highly selected, have demonstrated a very high mortality following acute basilar artery occlusion. The more widespread availability and use of non-invasive vascular imaging over recent years has increased the rate of ABAO diagnosis. OBJECTIVES To estimate the proportion of diagnosed ABAO among all-cause ischemic(More)
PURPOSE Platelets play a critical role in the pathogenesis of acute brain ischaemia. We studied the association between the degree of inhibition of platelet function by aspirin (ASA) and the severity and outcome of acute brain ischaemia. METHODS Platelet responsiveness to ASA was assessed in patients with acute brain ischaemia, treated with ASA since(More)
