Sex Differences in the Management of Advanced Heart Failure

Heart failure (HF) is prevalent among women and remains a leading cause of morbidity and mortality in the United States. Currently, 3 million women live with HF and the prevalence is projected to continue to increase. The purpose of this review is to highlight sex differences in the use and response to evidence-based pharmacological, device, and advanced HF therapies, as well as explore emerging areas of research in sex differences in the treatment of HF.

Under-representation of women in clinical HF trials has limited our understanding of sex-related differences in the treatment and outcomes of HF. Important sex differences exist in the use of evidence-based HF therapies and clinical response among women with HF. In general, women tend to obtain the same clinical benefit from evidence-based HF drug and device therapies, but the utilization rates of guideline-directed medical therapies remain poor compared to men. Future research efforts should focus on increasing the enrollment of women in HF trials to help gain helpful insight into sex-specific differences in treatment effects and subsequent clinical outcomes.
