Advanced and Accurate Mobile Health Tracking Devices Record New Cardiac Vital Signs

Area of Science:

• Cardiology
• Digital Health
• Biomedical Engineering

Background:

• Cardiovascular disease is a leading global cause of mortality.
• Healthcare systems face increasing demands, necessitating innovative monitoring solutions.
• Out-of-office monitoring of cardiovascular risk factors is crucial for future disease prevention.

Purpose of the Study:

• To develop and validate a scalable mHealth platform for tracking cardiovascular vital signs.
• To assess the feasibility and accuracy of remote monitoring of pulse wave velocity (PWV) and blood pressure.
• To evaluate participant satisfaction and adherence in a real-world setting.

Main Methods:

• A customized smartphone app and mobile health devices were used to collect data from approximately 250 adults over 17 weeks.
• Participants tracked pulse wave velocity (PWV), blood pressure, heart rate, physical activity, and sleep duration.
• Enrollment and consent were managed entirely through the smartphone app.

Main Results:

• 73% of participants successfully measured blood pressure and PWV within an hour for at least 14 weeks.
• Tracked cardiovascular vital signs and lifestyle factors closely matched population averages or controlled study values.
• High participant satisfaction was reported, indicating user acceptance of the mHealth approach.

Conclusions:

• mHealth technology offers an accurate and user-friendly method for at-home tracking of cardiovascular vital signs, including PWV.
• This approach demonstrates potential for scalable, remote monitoring to aid in cardiovascular disease prevention.
• Challenges in implementation were identified, providing insights for future mHealth platform development.
