Abstract
Pulmonary arterial hypertension (PAH) is characterized by progressive limitations in physical activity and health-related quality of life (HRQoL). HRQoL deficits may extend beyond the traditional domains of physical activity, psychological health, and emotional wellbeing to sexual health and function. Sexual HRQoL has not been studied in PAH, nor has the impact of PAH therapies themselves on sexual health and intimacy. In this initial investigation, we sought to explore HRQoL among women diagnosed with PAH and to determine if PAH treatment type (intravenous or subcutaneous prostanoids versus oral medications) was associated with levels of self-reported HRQoL assessed by validated measures for PAH-specific, general, and sexual HRQoL. We administered the emPHasis-10, Short Form (SF)-36, Female Sexual Dysfunction Scale-Revised (FSDS-R), and the Arizona Sexual Experience Scale (ASEX) to 35 women with self-reported World Health Organization Group 1 PAH at the 2016 Pulmonary Hypertension Association International Conference and Scientific Sessions. HRQoL instruments demonstrated excellent internal reliability. Women with PAH had high levels of sexual distress captured with the FSDS-R scale. The FSDS-R (but not ASEX) was significantly correlated to emPHasis-10 ( r = 0.64, p < 0.01) and most SF-36 domains ( r = - 0.36 to - 0.64, p < 0.05). Participants treated with intravenous or subcutaneous prostanoids had higher (worse) FSDS-R scores than those on oral therapies while ASEX, emPHasis-10, and SF-36 scores were similar across treatment types. Sexual HRQoL may impact overall quality of life in PAH and specific assessment of sexual health and functioning within intimate relationships may detect deficits in wellbeing not addressed by established HRQoL metrics. Further study to address all aspects of HRQoL in PAH is required.
