Randomized Controlled Trial of Two Mobile Health Strategies to Manage Postpartum Hypertension
(SMART BP)
What this study is about
A conducted at multiple hospitals randomly assigned trial that will compare the effectiveness of two postpartum blood pressure (BP) management strategies in improving blood pressure and cardiac function and increasing patient engagement and feeling of control over one's health
View original scientific description
A multicenter randomized trial that will compare the effectiveness of two postpartum blood pressure (BP) management strategies in improving blood pressure and cardiac function and increasing patient engagement and feeling of control over one's health
Interventions
OTHER
High-touch blood pressure management
Twelve weeks of text-based home blood pressure monitoring with BP self-management and team-based care
OTHER
Low-touch blood pressure management
10 days of text-based home blood pressure monitoring
Primary outcome measures
Mean diastolic blood pressure (DBP)
Time frame: 12 months postpartum
Assessed by 24-hour ambulatory blood pressure monitor (ABPM)
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria

- Initiation of blood pressure medication prior to hospital discharge and up to 14 days postpartum
- English or Spanish speaking (able to read/understand consent and instructions)
- Has phone texting capabilities
Exclusion criteria
- Diagnosis of chronic hypertension prior to delivery (would therefore include super imposed preeclampsia)
- Pre-existing cardiovascular disease (including prior myocardial infarction, stroke, heart failure with reduced ejection fraction, ventricular tachycardia, prior cardiac arrest, pacemaker, severe valvular heart disease, or prior cardiac surgery)
- Chronic kidney disease (stage 3 or higher)
- Using ≥3 BP medications at time of enrollment

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
