The C-Reactive Protein/Albumin Ratio (CAR) is being explored as a potential predictor for severe health outcomes in diseases, particularly in aneurysmal subarachnoid hemorrhage (aSAH).
A systematic review of existing studies was conducted, which revealed that higher CAR levels correlate with worse outcomes, such as lower Glasgow Outcome Scale scores and higher in-hospital mortality rates.
However, the evidence remains limited, and more prospective studies are needed to establish CAR’s role in long-term prognosis and to identify optimal cut-off points for its use.
