Sexual Dimorphism of Plasma Proteomes in Human Calcific Aortic Valve Stenosis


ABSTRACT: Females are underrepresented in studies of calcific aortic valve stenosis (CAVS), leading to delay in timely intervention and increased mortality. Histopathology demonstrates female CAVS presents with decreased valvular calcification but increased fibrosis and severity of symptoms. CAVS plasma samples (n=20 females, n=30 males) were analyzed for circulating sex-specific biomarkers via LC-MS/MS.

<h4>Background</h4>Calcific aortic valve stenosis is a global clinical burden, impacting around 2% of the population over 65 years of age. No pharmacotherapeutics exist, with surgical repair and transcatheter valve replacement being the only intervention. Females are underrepresented in studies of calcific aortic valve stenosis, leading to delay in timely intervention and increased mortality. Histopathology demonstrates female calcific aortic valve stenosis presents with decreased valvular calci  ...[more]
