The University of Tokyo Hospital Launches Large-Scale Clinical Study on AI Output and Exercise Capacity Using Apple Watch

(TOKYO, JAPAN) The University of Tokyo Hospital has started a large-scale clinical study investigating the relationship between exercise capacity and AI output using the Apple Watch. This study, part of a project selected under the Japan Agency for Medical Research and Development (AMED) initiative, aims to enable the detection of heart failure at home without relying on physician expertise.

For this project, SIMPLEX QUANTUM provided technological support by developing an AI program and a dedicated smartphone application, which the University of Tokyo Hospital uses for data collection and analysis.

Study Overview

The study examines the effectiveness of NIHA-HF, one of the AI modules in "SQ Library" that we have developed. Participants use the research application "Heart Health Monitor," available on the Apple App Store, to provide real-time ECG data, along with survey responses on medical history, lifestyle, and exercise capacity levels.

Data Collection: Apple Watch ECG recordings and survey responses are collected via the study app.

AI Analysis: The NIHA-HF algorithm analyzes the collected ECG data to investigate the correlation between exercise capacity and ECGs

Medical Follow-up: A subset of participants receives additional follow-up support from physicians at the University of Tokyo Hospital through email and phone consultations.

This initiative represents a significant step in validating NIHA-HF, an AI-powered system capable of detecting heart failure severity using single-lead ECG data. By integrating wearable technology with AI, this study contributes to the growing field of digital health solutions and remote patient monitoring.

While the number of diseases for which telemonitoring and medical treatment systems can be applied is increasing and is expected to extend healthy life expectancy and prognosis, as well as reduce medical costs, the use of such systems for heart failure is still extremely limited even worldwide. We will continue our efforts to make Japan a leading country in home healthcare for heart failure.

SIMPLEX QUANTUM remains committed to advancing AI-driven solutions and supporting research initiatives like this to contribute to digital health innovation and remote monitoring.
