Ultra-early Chest CT for SAP Prediction

Stroke-associated pneumonia (SAP) is a common and serious complication after acute ischaemic stroke (AIS). Existing scores rely mainly on clinical variables, and the added prognostic value of inflammatory markers and early chest CT findings remains uncertain. We developed and externally validated an early multimodal model combining clinical severity, inflammation, and chest CT abnormalities, and explored risk-stratified associations between prophylactic antibiotics and SAP.
