High-dose iron pills do not improve exercise capacity for certain type of heart failure

High-dose iron pills do not improve exercise capacity in people with a certain type of heart failure frequently marked by iron deficiency, researchers are reporting.  In a study that measured exercise capacity among 225 patients with heart failure with reduced left ventricular ejection fraction, the researchers found no significant difference between those who received iron pills and those who received placebo after 16 weeks of treatment. The study, published in JAMA, is partly funded by NHLBI.
