NCT ID NCT06499974

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study is observing 1000 adults having moderate- to high-risk surgery to see if the type and severity of anemia they have before surgery affects their risk of complications like heart injury, kidney injury, or stroke. Researchers will compare patients with iron-deficiency anemia, anemia of chronic disease, or combined anemia, and also compare them to patients without anemia. The goal is to better understand which patients are at highest risk so doctors can take steps to prevent problems.
