Does nocturnal hypertension reclassify maternal-fetal risk in women with white-coat hypertension? A cohort study in the second half of pregnancy
Nighttime blood pressure monitoring in pregnancy identifies hidden hypertension risk missed by office checks alone.
This retrospective cohort of 991 high-risk pregnant women demonstrates that white-coat hypertension with nocturnal hypertension carries preeclampsia risk (OR 11.95) similar to sustained hypertension, contradicting the traditionally benign prognosis assigned to WCH in pregnancy. The finding supports incorporating nighttime ambulatory BP monitoring into routine management of elevated office BP during pregnancy.
