In 90 patients with prosthetic heart valves, the presence of iron and folate deficiencies was assessed in a double-blind study. Anemia was found in 18 cases. Average serum iron levels were below the normal range and could be incremented significantly through the administration of 193 mg Fe++ daily during a 4-week period. No evidence of folate deficiency was found.
