Pan‐Immune‐Inflammation Value for Mortality Risk Stratification in Critically Ill Patients With Acute Ischemic Stroke: A Cohort Study Based on the MIMIC ‐ IV Database

Key Points

• This research aims to explore the relationship between Pan-Immune-Inflammation Value and mortality risk in patients with acute ischemic stroke.
• Cohort study design using the MIMIC-IV database
• Analysis of the relationship between PIV and mortality risks in critically ill patients
• Evaluation of short- and long-term all-cause mortality (ACM) outcomes
• PIV showed a reverse L-shaped relationship with short- and long-term ACM
• Demonstrated utility of PIV for risk stratification in critically ill acute ischemic stroke patients
