The CHIPS Trial (Control of Hypertension In Pregnancy Study)


Gestational Hypertension

What is the purpose of this trial?

The investigators do not know which approach to treatment of non-severe high blood pressure in pregnancy is better for women and babies.

In the CHIPS Trial, the investigators seek to determine whether 'less tight' control (aiming for a diastolic blood pressure [dBP] of 100 mmHg), compared with 'tight' control (aiming for a diastolic blood pressure [dBP] of 85 mmHg) can decrease the risks of adverse baby outcomes without increasing the risk of problems for the mother.
