First seen Nov 01, 2025 · Last updated Jun 17, 2026 · Updated 33 times
Summary
This study looked at 1,424 veterans at high risk for heart problems who had major surgery. It compared two approaches to blood transfusion: a liberal strategy (transfusing when hemoglobin drops below 10) versus a restrictive strategy (transfusing only when hemoglobin drops below 7). The goal was to see which approach better prevents complications like heart attack, kidney failure, stroke, or death within 90 days after surgery.
