Cardiac valvular abnormalities associated with use and cumulative exposure of cabergoline for hyperprolactinemia: the CATCH study.

Among community-based adults treated for hyperprolactinemia, cabergoline use and greater cumulative cabergoline exposure were associated with a higher prevalence of primarily mild valvular regurgitation compared with bromocriptine. Research is needed to clarify which patients treated with dopamine agonists may benefit from echocardiographic screening and surveillance.
