Key result
Plasma volume expansion significantly increased ANP levels in preeclamptic women (from 21.4 to 34.1 pg/ml, p=0.01), a greater response than observed in normotensive pregnant women.
Why the study?
Does acute plasma volume expansion cause a greater increase in atrial natriuretic peptide (ANP) levels in preeclamptic women compared to normotensive pregnant women?
Population
14 pregnant women in their last trimester (n=7 preeclamptic and n=7 normotensive).

Highlights potential vascular compliance differences in preeclampsia; leaves open whether ANP response informs volume management.
Does acute plasma volume expansion cause a greater increase in atrial natriuretic peptide (ANP) levels in preeclamptic women compared to normotensive pregnant women?
Absolute Event Rate: 34.1% vs 27.2%
p-value: p=0.01
Preeclampsia is associated with an exaggerated ANP release in response to acute plasma volume expansion, likely reflecting decreased compliance of capacitance vessels.
Özcan et al. (2010) studied Preeclampsia (n=14). Plasma volume expansion with 0.9% Ringer's solution vs. Normotensive pregnant women was evaluated on Postinfusion ANP levels (p=0.01). Plasma volume expansion significantly increased ANP levels in preeclamptic women (from 21.4 to 34.1 pg/ml, p=0.01), a greater response than observed in normotensive pregnant women.
