title: Beyond malignancy: the role of carbohydrate antigen 125 in heart failure.
abstract: Carbohydrate antigen 125 (CA-125), traditionally a tumor marker for screening, diagnosis, and monitoring in ovarian malignancy, had recently been shown increasing evidence and more extensively recognized/explored as a novel surrogate of heart failure (HF). The exact mechanisms underlying the pathophysiologic link between elevated serum CA-125 concentration and HF may be multi-factorial, with both mechanical and inflammatory process including numerous potential cytokines involved. Accumulating data had consistently indicated its diagnostic and prognostic role in HF patients in various clinical settings, however, there is limited clinical information regarding the incremental value or head-to-head comparison of such marker to other well-established HF markers. In this brief review, we aimed to discuss the biosynthesis, and potential insights of underlying pathophysiologies associated with CA-125 secretion in the scenarios of cardiac structural/functional alterations and HF, and further explored its current usage and roles in several recent reports.
