Pre-eclampsia superimposed on chronic hypertension
If a woman with pre-existing hypertension develops superimposed pre-eclampsia, it may be difficult to diagnose, particularly if she also has pre-existing proteinuria due to renal disease. However, in general terms, if a woman with pre-pregnancy hypertension develops worsening hypertension in combination with either proteinuria, new organ dysfunction or uteroplacental dysfunction, then pre-eclampsia may be diagnosed.
