NCT ID NCT04945707

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether a single dose of intravenous iron (ferric derisomaltose) can improve exercise capacity in people with heart failure with preserved ejection fraction who also have iron deficiency. About 66 adults will receive either the iron infusion or a placebo, and their oxygen use during exercise will be measured after 12 weeks. The goal is to see if correcting iron deficiency helps them feel less tired and do more physical activity.
