Contraceptive Options for the Patient with Pulmonary Arterial Hypertension
The World Health Organization describes contraception as desirable for many reasons. It allows families to make informed choices about their reproductive years. It allows family planning, with spacing of children, leading to better bonding between mother and child, higher exclusive breastfeeding rates, and improved health of the mother for a future pregnancy.1 Unintended pregnancies continue to occur at an astronomically high rate in the US, as high as 35% by most recent data,2 and of course, since women with pulmonary arterial hypertension (PAH) are not exempt from this statistic, it is imperative that as care providers, we help our patients to plan ahead. In their case, maternal health is our main concern. Weiss and colleagues, reporting on pregnancy outcomes with PAH between 1978 and 1996, found a maternal mortality of 36% in Eisenmenger syndrome, 30% in idiopathic PAH, and 56% in secondary PAH.3 A more recent systematic review reported slightly more optimistic pregnancy outcomes from 1997 to 2007. Still, maternal mortality ranged from 17% to 33%, depending on the exact etiology of pulmonary hypertension.4 It is therefore very clear that in the setting of PAH, contraception is important and potentially lifesaving.
