High Output Heart Failure

Summary: This infographic details the pathophysiology and etiology of high output heart failure, a condition where excessive demand on the heart leads to elevated cardiac output but ultimately results in heart failure symptoms. Key etiologies include conditions that decrease systemic vascular resistance (SVR) or increase oxygen consumption, such as obesity, arteriovenous fistulas, cirrhosis, and severe anemia. The resulting increase in cardiac output, combined with chronic SVR reduction and increased preload, can lead to heart failure due to compensatory mechanisms like fluid retention.
