Critical value of platelet transfusion to reduce the risk of death in aortic dissection (AD) patients: a study based on the MIMIC-IV database.

Key Points

To identify critical platelet transfusion rates that influence mortality risk in aortic dissection patients.
Analyzed data from the MIMIC-IV database
Computed transfusion rates
Evaluated risk of death based on transfusion rates
Identified 144.75 mL/h as the inflection point for death risk
Found 282.5 mL/h as the nadir for in-hospital death risk

Abstract

A platelet transfusion rate of 144.75 mL/h was the inflection point for the risk of death in patients with AD, whereas a platelet transfusion rate of 282.5 mL/h was the nadir for the risk of in-hospital death.
