Objective:The aim was to evaluate the prevalence of nocturnal and masked hypertension and the prognostic values of these blood pressure (BP) abnormalities in normotensive women coursing a high-risk pregnancy.Methods:The study was performed in pregnant women with 20 or more weeks of gestation coursing a high-risk pregnancy, sent to a specialized hypertension department to perform a prospective defined protocol of BP evaluation. Women with office BP at least 140/90mmHg were excluded. An ambulatory monitoring of BP was performed to identify masked and nocturnal hypertension (defined according to the current guidelines). The adjusted risk for development of preeclampsia/eclampsia (PEEC) was estimated using logistic regression. The ability of SBP and DBP to identify risk of PEEC was estimated using area under the receiver-operating characteristic curves.Results:Eighty-seven women (297 years old, 30 +/- 5 weeks of pregnancy) were included in this analysis. The prevalence of masked hypertension was 33.3%. Nocturnal hypertension was found in 42.5% of the women. Remarkably, 27.0% of the women with nocturnal hypertension had normal 24-h values according to ambulatory BP monitoring. Twenty-two patients developed PEEC; adjusted relative risks increased with the presence of nocturnal (odds ratio=4.72, 95% confidence interval 1.25-19.43, P=0.023) or masked hypertension (odds ratio=7.81, 95% confidence interval 2.6-22.86, P=0.001). Nocturnal SBP and DBP had the highest abilities to predict PEEC (area under the curve=0.77 and 0.80, respectively).Conclusion:Masked and nocturnal hypertension are frequent findings in normotensive women coursing a high-risk pregnancy, and their presence implies an increased risk to develop PEEC.
