title: Pregnancy-associated hypertension, a comparison of its prediction by 'roll-over test' and plasma noradrenaline measurement in 100 primigravidae.
abstract: One hundred primigravidae had a 'roll-over test' between 28 and 32 weeks of gestation. Of the 10 women with positive results (a rise of greater than or equal to 20 mmHg in diastolic blood pressure after roll-over) only two later developed diastolic blood pressures greater than 90 mmHg. Of the 90 patients with a negative result, 17 subsequently sustained diastolic pressures of greater than 90 mmHg. The change in plasma noradrenaline levels measured before and after roll-over, in all patients, did not distinguish between those patients who remained normotensive and those who subsequently developed hypertension. At 28-32 weeks gestation, those patients who subsequently developed hypertension had a higher mean plasma noradrenaline level and a higher systolic blood pressure than the patients who remained normotensive.
