OBJECTIVE: To compare peripheral pulse pressure waveforms in normal pregnancy, gestational hypertension (GH) and pre-eclampsia (PE). DESIGN: Comparative study. SETTING: Tertiary referral teaching hospital. SAMPLE: Women with hypertensive disease in pregnancy and matched normal pregnant controls. METHODS: Women in the third trimester of pregnancy with newly developed PE (n= 27) or GH (n= 33) were studied by radial artery applanation tonometry. Values were compared with those for gestational age matched normal pregnant women (n= 39). MAIN OUTCOME MEASURES: Augmentation Index. RESULTS: Hypertension was of equal severity in PE and GH. Central augmentation pressure and augmentation index, indicating vasoconstriction, were mildly elevated in GH, but markedly elevated in PE. CONCLUSION: Non-invasive applanation tonometry discriminates among normal pregnancy, GH and PE, and may be useful to predict PE.
