High output heart failure is characterized by reduced systemic vascular resistance, high cardiac output, and salt and water retention. The causes of high output heart failure include hyperthyroidism, sepsis, thiamine deficiency, chronic anemia, arteriovenous fistulae, chronic lung disease, liver cirrhosis, and Paget's disease of bone. Heart failure occurs when the cardiac output is insufficient to supply the oxygen demand of the body, even with high cardiac output (>8L/min), and the shortage of blood supply causes a neurohormonal response similar to that seen in common heart failure, including activation of the renin-angiotensin-aldosterone system, adrenergic nervous system, and/or an excess of antidiuretic hormone. Although there is no standard treatment for high output heart failure, the treatment of the cause of high output, resolving salt and water retention, and controlling systemic vascular resistance are required.
