Primary Outcome Measures

Name	Time	Method
Blood pressure control and anti-hypertensive medication requirement. Blood pressure will be measured using an automated syphygomanometer to help with blinding of the measurement. All women will be seated for at least 10 minutes and have their feet resting comfortably on the floor. BP measurements will be routinely taken from the left arm. Patients need for anti-hypertensive management will be asssessed separately by obstetric medicine specialists who are blinded to the study and will make their own assessments. Anti-hypertensive medication will be prescribed following a standardised protocol based on current best practice.[Every 2 weeks throughout the pregnancy and also at 32 weeks gestation.]

Secondary Outcome Measures

Name	Time	Method
The following pregnancy related complications will be recorded as adverse pregnancy outcomes: Pre-term delivery (delivery before 37/40 gestation), perinatal death, pre-eclampsia, foetal growth restriction (based on local growth charts), and initial Apgar score of less than or equal to 7. This information is routinely collected and will be obtained from the obstetric notes.[End of pregnancy.]
