In four the interval between the start of oral contraception and the diagnosis of malignant hypertension was less than four months, and ...
Redman C W - - 1987
The poor perinatal outcome of pregnant women with chronic hypertension depends on their increased susceptibility to superimposed preeclampsia. There is no direct evidence that this is mediated by hypertension and reduced by antihypertensive treatment. In particular, the arterial lesions of the uteroplacental circulation in preeclampsia also occur in normotensive individuals ...
Reiss R E - - 1987
A decrease in systemic blood pressure by midtrimester of normal pregnancy has been observed by many investigators. To examine the timing of onset of this decline and to study early behavior of blood pressure in pregnancies complicated by preeclampsia, we reviewed the outpatient charts of all patients with preeclampsia who ...
