Is this trial a fit for you?

Likely a good fit

Ideal candidates are elderly patients aged 70 and older who are undergoing elective cardiac surgery and have moderate postoperative iron deficiency anemia.

Probably not a fit

Patients with a history of iron overload, severe renal failure, or recent intravenous iron treatment may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to evaluate the effectiveness of intravenous iron treatment for older patients experiencing postoperative anemia following elective cardiac surgeries, such as aortic valve repair and coronary artery bypass grafting. The study will involve 310 patients aged 70 and above, who will be randomly assigned to receive either intravenous iron or a placebo. The primary outcome will be assessed using the World Health Organization Disability Assessment score 90 days after surgery, alongside secondary measures related to dyspnea and health-related quality of life. The trial is designed as a double-blind, placebo-controlled study conducted at two centers.

Why it matters

Potential benefit: If successful, this treatment could significantly improve recovery and quality of life for older cardiac surgery patients suffering from postoperative anemia.

How similar studies have gone: Other studies have shown promising results with intravenous iron treatment for anemia, suggesting potential success for this approach.
