Who this trial is looking for
This trial is looking for pregnant women with mild high blood pressure. Participants will either receive treatment to lower their blood pressure or usual care during their pregnancy.
Are You a Good Fit for This Trial?
You may be able to join if
I have a single baby due
I do not have any fetal problems
My blood pressure is between 130-139/80-89mmHg on two different occasions
I plan to give birth at UAB Hospital
I do not need to terminate my pregnancy
I am receiving care at UAB prenatal clinics
You may not be able to join if
I do not want to participate
I already have chronic hypertension or take high blood pressure medicine
I have experienced fetal loss before this trial
I have been diagnosed with major fetal abnormalities before this trial
I cannot take first-line medications like Nifedipine or Labetalol
I have other health issues that require lower blood pressure than 130/80mmHg

The CHAP2 study is designed to provide preliminary data for a larger multicenter study to assess whether treatment of stage 1 hypertension (HTN) in pregnancy improves maternal and or neonatal outcomes. The primary objective of this pilot study is to determine if anti-HTN treatment to BP\<130/80mmHg in pregnant patients with stage 1 HTN is associated with a difference in birthweight percentile at d…
The CHAP2 study is designed to provide preliminary data for a larger multicenter study to assess whether treatment of stage 1 hypertension (HTN) in pregnancy improves maternal and or neonatal outcomes. The primary objective of this pilot study is to determine if anti-HTN treatment to BP\<130/80mmHg in pregnant patients with stage 1 HTN is associated with a difference in birthweight percentile at delivery. Patients with stage 1 hypertension in pregnancy will be randomized to BP goals of \<130/80mmHg or usual care to treatment only if BPs ≥140/90mmHg. For this pilot, the investigator will randomize a total of 74 eligible participants, 37 to active treatment to BP\<130/80mmHg and 37 to usual care.
