OBJECTIVE Impaired blood pressure regulation in the acute phase of stroke has been associated with less favorable outcome. Mechanisms and effects of blood pressure dysregulation in stroke are not well understood; however, central autonomic impairment with sympathetic overactivity and baroreflex involvement are discussed. Baroreflex sensitivity (BRS) in(More)
INTRODUCTION The impact of anemia on functional outcome and mortality in patients suffering from non-traumatic intracerebral hemorrhage (ICH) has not been investigated. Here, we assessed the relationship between hemoglobin (HB) levels and clinical outcome after ICH. METHODS One hundred and ninety six patients suffering from supratentorial, non-traumatic(More)
OBJECTIVES Autonomic impairment after acute traumatic brain injury has been associated independently with both increased morbidity and mortality. Links between autonomic impairment and increased intracranial pressure or impaired cerebral autoregulation have been described as well. However, relationships between autonomic impairment, intracranial pressure,(More)
BACKGROUND AND PURPOSE Antiplatelets (APs) may increase the risk of symptomatic intracerebral hemorrhage (ICH) following intravenous thrombolysis after ischemic stroke. METHODS We assessed the safety of thrombolysis under APs in 11,865 patients compliant with the European license criteria and recorded between 2002 and 2007 in the Safe Implementation of(More)
BACKGROUND AND PURPOSE Impairment of cerebrovascular autoregulation may promote secondary brain injury in acute brain insults. Until now, only limited data are available on autoregulation in patients with spontaneous intracerebral hemorrhage. In the current study, we aimed to investigate cerebrovascular reactivity and its significance for outcome in(More)
BACKGROUND AND PURPOSE Impaired baroreflex sensitivity (BRS) has been previously shown to be of prognostic value in patients with cardiovascular disease and stroke. Because baroreflex seems to be blunted by both carotid atherosclerosis and by lesions affecting central processing, controversy exists regarding the etiology of stroke-related baroreflex(More)
BACKGROUND The cerebral pressure reactivity index (PRx) correlates with the outcome in intracerebral haemorrhage (ICH) patients and has been used to define an autoregulation-oriented "optimal cerebral perfusion pressure" (CPPopt). PRx has been calculated as a moving correlation coefficient between mean arterial pressure (MAP) and intracranial pressure (ICP)(More)
BACKGROUND Perihematomal edema and secondary brain injury may influence the clinical course after intracerebral hemorrhage (ICH). The role of blood pressure (BP) in edema formation in ICH has not been studied sufficiently. We hypothesize that impaired blood pressure regulation (as measured by baroreflex sensitivity) leading to excessive BP fluctuations may(More)
BACKGROUND The aim of the current study was to assess the occurrence of infection and its impact on the short- and long-term outcome of patients with supratentorial intracerebral hemorrhage (ICH). METHODS 247 patients suffering from supratentorial ICH were extracted from our local stroke database. Complete data sets including long-term functional outcome(More)
INTRODUCTION Current guidelines for spontaneous intracerebral hemorrhage (ICH) recommend maintaining cerebral perfusion pressure (CPP) between 50 and 70 mmHg, depending on the state of autoregulation. We continuously assessed dynamic cerebral autoregulation and the possibility of determination of an optimal CPP (CPPopt) in ICH patients. Associations between(More)
