Although CHF is usually associated with low cardiac output, "high output failure" can occur as well. In this condition, cardiac output is normal or even high but not high enough to meet markedly elevated metabolic demands of the heart in certain conditions. Those conditions include: severe anemia, thyrotoxicosis, lartge arteriovenous sunts, Beriberi, and Paget disease of the bone.
