Comparative Study
A population-based analysis of ethnic differences in admission to the intensive care unit after stroke.
Mexican-Americans (MAs) have shown lower post-stroke mortality compared to non-hispanic whites (NHWs). Limited evidence suggests race/ethnic differences exist in intensive care unit (ICU) admissions following stroke. Our objective was to investigate the association of ethnicity with admission to the ICU following stroke. ⋯ No overall association between ethnicity and ICU admission was observed in this community. ICU utilization alone does not likely explain ethnic differences in survival following stroke between MAs and NHWs.

Hematoma expansion after acute intracerebral hemorrhage occurs most frequently in patients presenting within 3 h of symptom onset. However, the majority of patients present outside this window or with an unknown onset time. We investigated the prevalence of hematoma expansion in these patients and assessed the accuracy of the CT angiography (CTA) spot sign for identifying risk of hematoma expansion. ⋯ A substantial number of patients destined to suffer from hematoma expansion present either late or with an unknown symptom onset time. The CTA spot sign accurately identifies patients destined to expand regardless of time from symptom onset, and may therefore open a path to offer clinical trials and novel therapies to the many patients who do not present acutely.

Cardiac injury is common after subarachnoid hemorrhage (SAH) and is associated with adverse early outcomes, but long-term effects are unknown. The first aim of this study was to compare the long-term rates of death, stroke, and cardiac events in SAH survivors versus a matched population without SAH. The second aim was to quantify the effects of cardiac injury on the outcome rates. ⋯ SAH survivors have increased long-term mortality and stroke rates compared with a matched non-SAH population. SAH-induced cardiac injury is associated with an increased risk of death and heart failure hospitalization.

Non-convulsive seizures (NCSZ) can be more prevalent than previously recognized among comatose neuro-intensive care patients. The aim of this study was to evaluate the frequency of NCSZ and non-convulsive status epilepticus (NCSE) in sedated and ventilated subarachnoid hemorrhage (SAH) patients. ⋯ Continuous EEG monitoring is important in detecting NCSZ in sedated patients. Continuous sedation, without wake-up tests, was associated with a low frequency of subclinical seizures in SAH patients in need of controlled ventilation.
