A Smartphone-Guided Digital Health Application for Hypertension: The Randomized Controlled HELP Trial

Area of Science:

• Cardiology
• Digital Health
• Hypertension Management

Background:

• Hypertension is a major risk factor for cardiovascular diseases.
• Current guidelines emphasize medication, lifestyle changes, and adherence.
• The Vantis app was developed to support hypertension management.

Purpose of the Study:

• To evaluate the efficacy of the Vantis app in lowering systolic blood pressure.
• To assess the impact of the Vantis app on therapy adherence and other health metrics.

Main Methods:

• A prospective, randomized trial involving 98 patients with uncontrolled hypertension.
• Patients were assigned to either the Vantis app intervention or standard care.
• The primary endpoint was systolic blood pressure reduction after 13 weeks.

Main Results:

• The Vantis app group showed a significantly greater reduction in systolic blood pressure (5.5 mmHg difference).
• Systolic blood pressure decreased by 12.4 mmHg in the intervention group versus 7.1 mmHg in the control group.
• Therapy adherence was higher in the intervention group; no adverse events were reported.

Conclusions:

• The Vantis app effectively lowers systolic blood pressure in hypertensive patients.
• This digital health application enhances patient adherence to treatment guidelines.
• The Vantis app shows promise as a tool for managing hypertension.
