Brief Summary: 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
Detailed Description: Primary research question

For pregnant women with non-severe non-proteinuric maternal hypertension at 14-33 weeks will less tight control target diastolic blood pressure dBP of 100 mmHg versus tight control target dBP of 85 mmHg increase or decrease the likelihood of pregnancy loss or Neonatal Intensive Care Unit NICU admission for greater than 48 hours

Secondary research question

Will less tight versus tight control increase or decrease the likelihood of serious maternal complications

Other research questions

Will less tight versus tight control

1 Increase or decrease the likelihood of serious perinatal complications
2 Increase or decrease the likelihood of severe hypertension and pre-eclampsia
3 Increase or decrease the likelihood of maternal satisfaction with care
4 Result in significant changes in dBP or health care costs

Treatment Allocation

Eligible women will be randomised centrally to either less tight control aiming for dBP of 100mmHg or tight control aiming for dBP of 85mmHg of their hypertension

Randomisation will be stratified by centre and type of hypertension pre-existing or gestational

In the less tight control group if dBP is 105mmHg then antihypertensive medication must be started or increased in dose
In the tight control group if dBP is 80mmHg then antihypertensive medication must be decreased in dose or discontinued
In both groups centres will provide their usual care Data will be collected on potential co-interventions eg hospitalisation bedrest

Outcomes

Primary Pregnancy loss miscarriage or ectopic pregnancy pregnancy termination stillbirth or neonatal death or high level neonatal care for 48 hours in the first 28 days of life or prior to primary hospital discharge whichever is later

Secondary Onemore serious maternal complications until six weeks postpartum

Follow-up

Compliance dBP and antihypertensive dose will be assessed within 4 weeks of randomisation Outcome data will be collected during the womans and babys hospital stay for birth or loss Women will be contacted 6 to 12 weeks after delivery or loss and for preterm babies when the baby is at 36 weeks corrected gestational age to enquire about satisfaction with care and any major maternalneonatal morbidity following hospital discharge
