Paradoxical fetal and maternal results of studies have led to inconsistent use of antihypertensive drugs or no treatment at all in mild to moderate gestational hypertension in the Netherlands. However, none of the studies have taken the individual maternal circulatory state or the contemplated blood pressure response into account. Hypertension may be accompanied by high (hyperdynamic vasodilated profile), normal (normodynamic profile) of low (hypodynamic vasoconstrictive profile) cardiac output, and preeclampsia is not restricted to one circulatory profile. Therefore antihypertensive drugs should be viewed upon as correctors of the hemodynamic state rather than solely reducers of blood pressure. Without taking the maternal hemodynamic profile and condition into account, generic antihypertensive treatment can be expected to result in disappointing, inadequate and paradoxical results. The investigators hypothesize that in mild to moderate hypertension, personalized hemodynamically guided antihypertensive therapy (with target systolic and diastolic blood pressure <130/80mmHg), prevents the progression to severe hypertension and/or preeclampsia compared to no treatment, without the alleged side-effects.

Inclusion Criteria

Patients ages 18years or older
Before 37 weeks of gestational age
Diagnosed with mild to moderate gestational hypertension

Exclusion Criteria

Women with severe hypertension: systolic blood pressure 160mmHg and/or diastolic blood pressure 110mmHg
Women with chronic hypertension who are already on antihypertensive drugs. If no antihypertensive drugs are used yet, women with pre-existent hypertension are eligible to participate
Women diagnosed with preeclampsia or eclampsia in the current pregnancy
Women who are not able to comprehend the study outline
Women who have already participated in this study cannot be included a second time
Women who have a (relative) contra-indication for one of the possible prescribed medications (for example women who have tested positive for antinuclear antibodies, which is a contraindication for Methyldopa)
Women who intend to terminate the pregnancy
Women who have a fetus with a major anomaly or chromosomal abnormality
