Conditions
Hypertensive Disorder of Pregnancy

Interventions
Other: Heart4U
Registration Number
NCT05995106
Lead Sponsor
Seoul National University Hospital
Brief Summary

Objectives: We have developed a cardiovascular disease management application named Heart4U, with the capability of integrating with the Electronic Medical Records (EMR) system within the hospital.

The main goal of this study is to evaluate the clinical effectiveness of a treatment approach that entails self-management of risk factors through a mobile application among pregnant individuals diagnosed with hypertensive cardiovascular conditions.

Methods: Patients assigned to the app group receive assistance from the research team to install the Heart4U application and familiarize themselves with its usage. Both the app group and the usual care group continue to receive active treatment as previously administered (guideline-based prenatal care). Follow-up observations occur at each obstetric examination prior to delivery and are conducted again at the first month postpartum. The primary endpoint of observation pertains to the difference in systolic blood pressure between the enrollment and study completion time points.

Detailed Description

Inclusion Criteria:

* Diagnosis: 1 or 2

1. Pregnant women diagnosed with hypertensive disorders of pregnancy at or beyond 12 weeks of gestation:

* Chronic hypertension: Diagnosed with hypertension within 20 weeks of gestation (elevated office/clinic blood pressure ≥140/90 mm Hg) or currently on antihypertensive medication.

* Gestational hypertension: Newly diagnosed with hypertension after 20 weeks of gestation (elevated office/clinic blood pressure ≥140/90 mm Hg) or currently on antihypertensive medication.

* Preeclampsia: Newly diagnosed with hypertension after 20 weeks of gestation (elevated office/clinic blood pressure ≥140/90 mm Hg) or currently on antihypertensive medication, and presents with proteinuria (300 mg/24 hours or urine protein-to-creatinine ratio ≥0.3), thrombocytopenia (less than 100,000 platelets per microliter), abnormal renal function (creatinine exceeding 1.1 or doubling of baseline), elevated liver enzymes (twice normal levels), neurological symptoms (headache, visual disturbances, seizures, etc.), and/or pulmonary edema.

* Superimposed preeclampsia: Diagnosed with hypertension within 20 weeks of gestation (elevated office/clinic blood pressure ≥140/90 mm Hg) or currently on antihypertensive medication, and experiences symptoms or signs related to superimposed preeclampsia.

2. Pregnant women at elevated risk for hypertensive disorders of pregnancy:

Multifetal gestation, obesity, uncontrolled gestational or pre-existing diabetes, history of hypertensive disorder of pregnancy leading to preterm birth, presence of borderline blood pressure readings during antepartum care (elevated office/clinic blood pressure ≥130/80 mm Hg) following a previous diagnosis of hypertension-related disorder in a prior pregnancy.

* Adult individuals aged 18 years and above who possess a smartphone and are capable of independently utilizing the application, among pregnant women.
