It is the development of proteinuria in pregnancy-induced hypertension which is associated with an increased perinatal mortality. There is some evidence to suggest that labetalol may diminish the amount of proteinuria in patients who have already developed proteinuric pre-eclampsia. A randomised controlled study design was used to investigate whether labetalol ...

The clinical significance of isolated systolic hypertension (systolic blood pressure greater than or equal to 160 mmHg and diastolic blood pressure less than 90 mmHg) has long been recognized, but its prevalence and correlates have not been well characterized. A community-based study was carried out by the Yang-Ming Crusade in ...

Normal pregnancy is associated with increased levels of digitalis-like factor (DLF) and erythrocyte sodium-lithium countertransport (RBC CTT), which return to normal levels postpartum. Patients with pregnancy-induced hypertension (PIH) have greater increases in both factors than women with normotensive pregnancies. This study was designed to determine if both abnormalities are observed ...

Reported central hemodynamics obtained with a Swan-Ganz pulmonary artery thermodilution catheter in preeclamptic patients show marked disparity, which has been interpreted to indicate a variable hemodynamic expression of the disease. However, the variability also may be due, at least in part, to the pharmacological treatment that most of the women ...
