Abstract

Purpose of Review

Prevalence and outcome differences between women and men with pulmonary arterial hypertension (PAH) raise questions about the role of sex hormones in disease pathobiology. This review will summarize the current understanding of sex and sex hormone pathways and their influence on heart-lung function in health and in disease.

Recent Findings

Female sex has been shown to be a risk factor for the development of PAH, but women have improved survival compared to men with PAH. These paradoxical observations are likely driven in part by complex sex hormone signaling and processing pathways and their interaction with the pulmonary vasculature and the right ventricle. These relationships may vary depending on an individual’s underlying sex, age, and/or genetic substrate.

Summary

The study of the connections between sex, sex hormones, the pulmonary circulation, and the right ventricle may improve our understanding of disease epidemiology and outcomes and lead to new treatment strategies for PAH.

This is the largest US PAH registry to date and reported a more pronounced sex bias than other registries. This raises the question whether there has been a true change in disease biology or whether the predominantly prevalent study population skews the bias, especially given a survival bias conferred by female sex.
