Anaemia in Heart Failure Patients, Associated with Angiotensin - Renin - Aldosterone System Altering Medications.

Heart failure (HF) remains one of the most common diseases and one of the major causes of death worldwide. HF is often associated with other chronic diseases, most commonly with anemia. Anemia increases patients' mortality and lowers their quality of life. There are a few pathophysiological mechanisms that explain anemia in patients with HF - hemodilution, absolute or functional iron deficiency, activation of the inflammatory cascade, chronic kidney disease, and impaired erythropoietin production and activity. Moreover, congestive HF is often treated with angiotensin-converting enzyme inhibitors and aldosterone receptors blockers, which could be linked to the development of anemia.
