BACKGROUND We sought to determine if monitoring heart rate variability (HRV) would enable preclinical detection of secondary complications after subarachnoid hemorrhage (SAH). METHODS We studied 236 SAH patients admitted within the first 48 h of bleed onset, discharged after SAH day 5, and had continuous electrocardiogram records available. The diagnosis(More)
INTRODUCTION Sympathetic nervous system hyperactivity is common after subarachnoid hemorrhage (SAH). We sought to determine whether uncontrolled prolonged heart rate elevation is a risk factor for adverse cardiopulmonary events and poor outcome after SAH. METHODS We prospectively studied 447 SAH patients between March 2006 and April 2012. Prior studies(More)
OBJECTIVE To assess the relationship between seizure burden on continuous EEG (cEEG) and functional as well as cognitive outcome 3 months after subarachnoid hemorrhage (SAH). METHODS The study included all consecutive patients with a spontaneous SAH admitted to the Columbia University Medical Center Neurological Intensive Care Unit and monitored with cEEG(More)
OBJECTIVE Nonconvulsive seizures (NCSz) are frequent following acute brain injury and have been implicated as a cause of secondary brain injury, but mechanisms that cause NCSz are controversial. Proinflammatory states are common after many brain injuries, and inflammation-mediated changes in blood-brain barrier permeability have been experimentally linked(More)
BACKGROUND Diffusion-perfusion mismatch (perfusion-weighted imaging [PWI] abnormality minus diffusion-weighted imaging [DWI] abnormality) can identify candidates for acute stroke intervention, but PWI is often not obtainable. The authors hypothesized that language tests can predict volume of hypoperfusion, and thus mismatch, in acute left hemisphere stroke,(More)
A strong relationship exists between cholesterol and atherosclero-sis, 1 with low density lipoprotein (LDL) being a major risk factor. 2 However, 50% of patients with acute coronary events have " normal " cholesterol, and 75% patients with premature coronary heart disease (CHD) have normal LDL. 3 Thus, contribution of other lipoproteins has been explored.(More)
BACKGROUND We sought to determine whether therapeutic temperature modulation (TTM) to treat fever after intracerebral hemorrhage (ICH) is associated with improved hospital complications and discharge outcomes. METHODS We performed a retrospective case-control study of patients admitted with spontaneous ICH having two consecutive fevers ≥38.3 °C despite(More)
BACKGROUND AND PURPOSE Therapeutic hypothermia is a potent neuroprotectant approved for cerebral protection after neonatal hypoxia-ischemia and cardiac arrest. Therapeutic hypothermia for acute ischemic stroke is safe and feasible in pilot trials. We designed a study protocol to provide safer, faster therapeutic hypothermia in stroke patients. METHODS(More)
INTRODUCTION Subarachnoid hemorrhage (SAH) is a devastating form of stroke. Causes and mechanisms of in-hospital death after SAH in the modern era of neurocritical care remain incompletely understood. METHODS We studied 1200 consecutive SAH patients prospectively enrolled in the Columbia University SAH Outcomes Project between July 1996 and January 2009.(More)
Symptomatic intracerebral hemorrhage (sICH) occurs in up to 7% of stroke patients treated with thrombolytic therapy. There are limited data on the effectiveness of the reversal agents used for intravenous tissue plasminogen activator related intracranial bleeds. We report a patient with sICH following intravenous thrombolysis whose intracerebral hemorrhage(More)
