Why the study?
In heart failure, survival is strictly related to exercise limitation, but the link between impaired iron transport, exercise limitation, and survival was undefined.
Does impaired iron transport affect exercise limitation and survival in patients with chronic heart failure?
Does impaired iron transport affect exercise limitation and survival in patients with chronic heart failure?
Impaired iron transport negatively affects survival in patients with chronic heart failure.
Answers are grounded in this paper and cite their sources.
May worsen survival in chronic heart failure; hypothesis-generating and requires prospective validation before practice change.
Background: Iron deficiency (ID) is frequent in chronic heart failure (HF). Among HF-ID patients those with impaired iron transport (IIT) (Transferrin saturation (TSAT) < 20 %) have the worst prognosis. In HF survival is strictly related to exercise limitation but the link between IIT, exercise limitation and survival is at present undefined. Methods: slope was assessed applying path analysis. Results: (52 %), contributing to the IIT negative effect on survival. Conclusions: slope.
