High Cardiac Output Heart Failure Induced by Chronic Severe Anemia / 대한내과학회지

High cardiac output heart failure (HCOHF) occurs in the setting of increased cardiac output, such as with chronic anemia, hyperthyroidism, beriberi, pregnancy, and an arteriovenous (AV) fistula. Of these, chronic anemia is a rare cause of HCOHF and its pathophysiology remains unknown. This report is about a patient with chronic anemia who presented with heart failure and severe tricuspid regurgitation. The severity of the tricuspid regurgitation and the patient's symptoms and signs were improved on correcting the anemia.
