Abstract


Background: To study the prevalence and pattern of iron deficiency (ID)in heart failure (HF) patients with or without anaemia.

Methods: This is a single-centre observational study, conducted at a tertiary care hospital of Punjab. Patients were selected based on validated clinical criteria-Framingham criteria. The iron parameters were done during the study including serum iron, serum ferritin, total iron binding capacity, and transferrin saturation (TSAT), to diagnose iron deficiency anaemia. Anaemia was defined as haemoglobin (Hb) < 13g/dl in males and <12 g/dL in females, based on WHO definition. Absolute iron deficiency is defined as serum ferritin < 100 mg/L and functional ID was defined as normal serum ferritin (100–300 mg/L) with low TSAT (<20%).

Results: A total of 120 patients of Heart Failure (54% males and 46% females) were studied. Most of the patients were of high-functional NYHA class (Class IV NYHA n=45). Iron Deficiency was present in 60% patients with 31.66% patients having absolute and 28.33% patients having functional ID. Nearly one-fifth of the patients were having ID but without anemia, signifying importance of workup of Iron deficiency other than haemoglobin levels.

Conclusions: Study highlights the neglected burden of ID in HF patients in India. This study suggests further large-scale studies to better characterize this easily treatable condition and considering routine testing in future Indian guidelines.
