This study evaluates the haemodynamic effects of anaemia on cardiac function and cerebral blood flow in heart failure patients supported with CF\u2010LVAD using computational simulations. A dynamic model simulating cardiac function, systemic, pulmonary and cerebral circulations, cerebral flow autoregulatory mechanisms and gas contents in blood was used to evaluate the effects of anaemia and iron deficiency in heart failure and during CF\u2010LVAD support. CF\u2010LVAD therapy was simulated by a model describing HeartMate 3. Anaemia and iron deficiency were simulated by reducing the haemoglobin level from 15 to 9\u2009g\/dL and modifying scaling coefficients in the models simulating heart chamber volumes. Reduced haemoglobin levels decreased the arterial O<jats:sub>2<\/jats:sub> content, which increased cerebral blood flow rate by more than 50% in heart failure and during CF\u2010LVAD assistance. Reduced haemoglobin levels simulating anaemia had minimal effect on the arterial and atrial blood pressures and ventricular volumes. In contrast, iron deficiency increased end\u2010diastolic left and right ventricular diameters in heart failure from 6.6\u2009cm to 7\u2009cm and 2.9\u2009cm to 3.1\u2009cm and during CF\u2010LVAD support from 6.1 to 6.4\u2009cm and 3.1 to 3.3\u2009cm. The developed numerical model simulates the effects of anaemia in failing heart and during CF\u2010LVAD therapy. It is in good agreement with clinical data and can be utilised to assess CF\u2010LVAD therapy.<\/jats:p>","DOI":"10.1002\/cnm.3781","type":"journal-article","created":{"date-parts":[[2023,10,10]],"date-time":"2023-10-10T09:42:46Z","timestamp":1696930966000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Computational
