AbstractThe objective of our study was to evaluate the predictive ability of second trimester mean arterial pressure (MAP) for proteinuric and non-proteinuric pregnancy induced hypertension. A prospective study of MAP in pregnancy was performed on 220 normotensive, primagravid, Chinese women, recruited in the second trimester of pregnancy. MAP was measured in the left lateral position after rest using a Dinamap automatic sphygmomanometer. Patients were followed until delivery and classified as either having remained normotensive, or having developed pregnancy induced hypertension, with or without proteinuria. Thirty-four pregnancies later developed pregnancy hypertension, of which 15 had significant proteinuria, either antenatally (nine cases) or in labour (six cases). Receiver operating characteristic curve analysis confirmed earlier reports that second trimester MAP is a good predictor of proteinuric pregnancy hypertension, but less able to predict non-proteinuric hypertension. Only one out of the 15 cases of proteinuric pregnancy hypertension had a second trimester MAP value below 68 mm Hg. We conclude that second trimester MAP predicts proteinuric better than non-proteinuric pregnancy-induced hypertension when measured under these conditions. © 1994 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
