    Background: Congestive heart failure (CHF) is usually associated with disorders causing low cardiac output; disorders associated with high cardiac output rarely cause CHF (1, 2). Medications have not previously been thought to cause high-output heart failure. New-onset CHF and cardiovascular death have rarely been associated with therapy with anagrelide (3-5), a novel treatment for essential thrombocytosis. The mechanism of cardiac dysfunction related to anagrelide has not previously been reported.

    Objective: To report a case of high-output heart failure …
