Office blood pressure measurement is not sufficient monitoring for women who have experienced severe preeclampsia, as it misses forms of hypertension commonly experienced in that population, according to a study published Feb. 5 in Hypertension .

Researchers at Erasmus University, Rotterdam, the Netherlands, conducted a retrospective cohort study of 200 women who underwent 24-hour ambulatory BP monitoring and office BP measurement at a 1-year follow-up for delivery with severe preeclampsia. Measurements were taken between 9 months and 15 months after delivery.

The 24-hour monitoring found that 64 (32%) and 85 (43%) of the 200 women had daytime and nighttime hypertension, respectively, but only 48 (24%) also would have been found to be hypertensive solely with office measurement. Forty-one women (21%) in the study previously had been diagnosed with hypertension and were receiving treatment.

“Current clinical guidelines on the prevention of [cardiovascular disease] and stroke after a hypertensive pregnancy disorder lack advice on [ambulatory BP monitoring] after delivery. We think that [ambulatory BP monitoring] should be offered to all women who experienced severe preeclampsia for more accurate BP assessment,” wrote Laura Benschop, MD, and her coauthors.
