Pressor responsiveness to angiotensin II in hospitalized primigravid women with pregnancy-induced hypertension.

Hospitalization of women with pregnancy-induced hypertension is beneficial in improving pregnancy outcome, but how it affects this physiologic process is not clear. In the present investigation, we evaluated pressor responsiveness to angiotensin II in 62 hospitalized women with pregnancy-induced hypertension. Although each of the women became normotensive, at least transiently, all remained sensitive to the pressor effects of angiotensin II. Thus, the beneficial effect of hospitalization on women with pregnancy-induced hypertension cannot be attributed to a decrease in the responsiveness to the action of angiotensin II.
