The effect of intravenous ferric carboxymaltose on health-related quality of life in patients with chronic heart failure and iron deficiency: a subanalysis of the FAIR-HF study
Aims Patients with chronic heart failure ( CHF ) show impaired health-related quality of life ( HRQoL ) , an important target for therapeutic intervention . Impaired iron homeostasis may be one mechanism underlying the poor physical condition of CHF patients . This detailed sub analysis of the previously published FAIR-HF study evaluated baseline HRQoL in iron-deficient patients with CHF and the effect of intravenous ferric carboxymaltose ( FCM ) on HRQoL. Methods and results FAIR-HF r and omized 459 patients with reduced left ventricular ejection fraction and iron deficiency , with or without anaemia , to FCM or placebo ( 2:1 ) . Health-related quality of life was assessed at baseline and after 4 , 12 , and 24 weeks of therapy using the generic EQ-5D question naire and disease-specific Kansas City Cardiomyopathy Question naire ( KCCQ ) . Baseline mean Visual Analogue Scale ( VAS ) score was 54.3 ± 16.4 and KCCQ overall summary score was 52.4 ± 18.8 . Ferric carboxymaltose significantly improved VAS and KCCQ ( mean differences from baseline in KCCQ overall , clinical and total symptom scores , P < 0.001 vs. placebo ) at all time points . At Week 24 , significant improvement vs. placebo was observed in four of the five EQ-5D dimensions : mobility ( P= 0.004 ) , self-care ( P < 0.001 ) , pain/discomfort ( P= 0.006 ) , anxiety/depression ( P= 0.012 ) , and usual activity  ( P= 0.035 ) . Ferric carboxymaltose improved all KCCQ domain mean scores from Week 4 onward ( P≤ 0.05 ) , except for self-efficacy and social limitation . Effects were present in both anaemic and non-anaemic patients . Conclusions HRQoL is impaired in iron-deficient patients with CHF .  Intravenous FCM significantly improved HRQoL after 4 weeks , and throughout the remaining study period . The positive effects of FCM were independent of anaemia status
