OMRON Healthcare Co., Ltd. and University of California, San Francisco are conducting a randomized controlled trial to assess whether home blood pressure monitoring can support early detection of atrial fibrillation (AFib) in patients with hypertension.
The study focuses on integrating AFib screening into routine hypertension management using connected health technologies. Target applications include cardiovascular monitoring, digital health systems, and remote patient management.
Clinical and technical context
AFib is a cardiac arrhythmia associated with increased risks of stroke, heart failure, and cardiovascular mortality. Its detection is challenging because a significant proportion of patients remain asymptomatic.
The collaboration addresses the need for scalable screening methods that can identify AFib earlier without increasing clinical workload. By leveraging existing home blood pressure monitoring practices, the study evaluates whether routine measurements can serve as a screening tool for arrhythmia detection.
Study design and system integration
The trial, titled OMRON-AF, is a fully remote randomized controlled study enrolling approximately 1,900 participants aged 60 and older with hypertension and additional AFib risk factors.
Participants are divided into two groups:
- One group uses home blood pressure monitors equipped with an embedded AFib detection algorithm
- The other uses standard monitoring devices without arrhythmia detection
The system integrates mobile health infrastructure through the OMRON Connect application, enabling remote recruitment, data collection, and patient engagement.
When potential AFib events are identified through home monitoring, participants receive a wearable electrocardiogram (ECG) patch for diagnostic confirmation. This combination of continuous screening and confirmatory diagnostics forms a hybrid monitoring model linking consumer devices with clinical-grade evaluation.
Measurement parameters and clinical evaluation
Beyond AFib detection, the study evaluates heart failure risk using NT-proBNP biomarker testing in diagnosed patients. It also analyzes AF burden, defined as the proportion of time spent in atrial fibrillation, measured via ECG monitoring.
These data are compared with episode frequency detected during home blood pressure measurements to assess the relationship between intermittent screening and continuous cardiac monitoring.
This approach enables evaluation of both diagnostic accuracy and the potential for ongoing disease management using home-based monitoring systems.
Expected impact on healthcare delivery
The study aims to determine whether integrating AFib screening into routine hypertension care can improve early diagnosis without increasing patient or healthcare system burden.
From a technical perspective, the approach leverages:

- Existing home monitoring infrastructure
- Algorithm-based detection within consumer medical devices
- Remote data acquisition and patient engagement via mobile applications
If validated, this model could support earlier intervention, reduce the incidence of stroke and heart failure, and provide a scalable framework for population-level cardiovascular screening.
Outlook for digital health integration
The collaboration reflects a broader shift toward decentralized clinical trials and remote patient monitoring. By combining medical device technology, mobile health platforms, and clinical research expertise, the project explores a model for integrating screening and diagnosis into everyday patient routines.
Such approaches may contribute to more efficient healthcare delivery and improved outcomes in chronic disease management.
