Context
Subarachnoid hemorrhage (SAH) has a high fatality rate and many suffer from delayed neurological deficits. Biomarkers may aid in the identification of high-risk patients, guide treatment/management and improve outcome.
Objective
The aim of this review was to summarize biomarkers of SAH associated with outcome.
Methods
An electronic database query was completed, including an additional review of reference lists to include all potential human studies.
Results
A total of 298 articles were identified; 112 were reviewed; 55 studies were included.
Conclusion
This review details biomarkers of SAH that correlate with outcome. It provides the basis for research investigating their possible translation into the management of SAH patients.
