High-output heart failure
sites • July 1, 2018
High-output heart failure usually involves increased cardiac output (CO) in response to a disturbance causing reduced systemic vascular resistance
Such disturbances include:
- Peripheral vasodilation due to unmet metabolic demand (eg, hyperthyroidism, severe anemia)
- Increased quantity of peripheral vessels (eg, Paget disease, morbid obesity)
- Bypass of systemic arteriolar resistance due to an enlarged arteriovenous fistula (as in this patient's case)
