What is the Apple Heart Study?
The Apple Heart Study is a research study conducted to learn if the Apple Heart Study app can use data from Apple Watch to identify irregular heart rhythms, including those from potentially serious heart conditions such as atrial fibrillation. Apple is conducting this research study in collaboration with Stanford Medicine to improve the technology used to analyze irregular heart rhythms. Early detection of irregular heart rhythms may prevent more serious health issues.
How does the study work?
The Apple Heart Study app uses data from Apple Watch to identify irregular heart rhythms, including those from potentially serious heart conditions such as atrial fibrillation. The Apple Heart Study app will notify you if the app identifies a possible irregular heart rhythm. As part of the study, you will be able to connect to a Study Telehealth Provider from American Well, and may be sent a small, discreet sensor device called an ePatch to wear for up to seven days. The ePatch adheres to your chest and is commonly used to monitor a person’s heart rhythm. After you return your ePatch, you will receive instructions to contact the Study Telehealth Provider who will review your ePatch results with you and may recommend that you seek further medical care from your own health care provider. The ePatch and the Study Telehealth Provider calls will be provided at no cost to you. However, any further medical care you seek from your own health care provider will be at your own cost.
Why should I participate?
One out of four individuals will have atrial fibrillation during their lifetime¹ a condition that significantly increases the risk of stroke and heart failure but often goes undiagnosed. You can help determine if the Apple Heart Study app together with Apple Watch can identify irregular heart rhythms, including those from potentially serious heart conditions such as atrial fibrillation.
Who can participate?
Anyone who meets all of the following criteria may participate in the study:
- 22 years or older
- Resident of the United States
- Comfortable with written and spoken English
- Has an iPhone 5s or later with iOS version 11.0 or later
- Has an Apple Watch Series 1 or later with watchOS version 4.0 or later
- Has never been diagnosed with atrial fibrillation, atrial flutter, and is currently not taking any anticoagulant medication
Which Apple Watch is compatible to use for the study?
Requires Apple Watch Series 1 (Fall 2016 model) or later with watchOS 4.0 and later. The Apple Heart Study does not support the original Apple Watch.
What will I need to do if I participate?
You will download the Apple Heart Study app and install on your iPhone and Apple Watch. You will need to wear Apple Watch during the study period for the app to analyze your heart rhythm. If the app identifies any heart rhythm abnormality, you will be able to talk with the Study Telehealth Provider from American Well, who may suggest you wear an ePatch for 7 days (provided at no cost). You will also be asked to complete up to three short surveys via the app and website during the study period.
Note: Enrollment for this study is closed to new participants as of August 1, 2018. If you are currently enrolled, your participation will continue until the end of the study.
What is heart rate and how does the Apple Watch measure my heart rate?
The heart rate is a measure of how fast or how slow your heart is beating. Learn more about the heart rate sensor on Apple Watch here: https://support.apple.com/en-us/HT204666
I think I have atrial fibrillation but a health care provider has not diagnosed me, can I still enroll?
Yes, you may still enroll if you have not been diagnosed with atrial fibrillation by a health care provider.
Is this going to cost me anything?
Apple is sponsoring this study. The study-related procedures, including study-related calls with the Study Telehealth Provider (if required) and the ePatch (if required) will be provided at no charge to you or your insurance company. There may be an indirect cost to participate in this study because the data collected for this study and transmitted to the study team will count against your phone’s data plan. A 10-minute study video visit will use approximately 20MB of your phone data when conducted via 3G/4G (rather than Wi-Fi).
If you are found to have an irregular heart rhythm, you are financially responsible for any follow-up treatment you seek from your own health care provider.
Medical care and services you decide to use because of study findings that are not part of this study (for example, Emergency Department visits or any subsequent treatment, whether recommended by the Study Telehealth Provider or not), may require co-payments if your insurance requires co-payment or may require you to bear the expenses if you do not have insurance. The sponsor will not be responsible for any costs beyond those described here.
How long will the study last?
Approximately 15 months, from November 29, 2017 to January 31, 2019.
What data will be obtained?
The study data that will be collected during your participation in the study includes data collected by the Apple Heart Study app (using Apple Watch and iPhone), the ePatch (only if you receive an ePatch), survey responses, and data collected by the Study Telehealth Provider (if applicable). For the purposes of data analyses, only coded study data (explained below) will be used.
What happens to my data?
The study data gathered will go to a secure database where your name and other identifying information will be removed and replaced with a random code to protect your privacy. Your coded data will then go to a secure database to be combined with the study data from other participants to be analyzed by the sponsor and Stanford.
Your data will be kept confidential except if disclosure is required by law or as described in the informed consent and authorization document, which you will review and sign before any data about you is collected. The study team will do its best to ensure that the study data is kept private and secure. Your data will be stored and transmitted using secure systems. If the results of this study are published or presented at meetings, your name and other directly identifying information will not be used and you will not be identified. Your coded study data may be used by the sponsor for FDA submission to seek approval of the investigational device and also for the development of health-related product development and improvement activities.
Who will have access to my data?
Apple Inc., Stanford University, Schulman Institutional Review Board (ethics committee), American Well and it’s clinical partner, Online Care Group (Study Telehealth Provider), Biotelemetry (ePatch provider), and its subsidiaries/affiliates, Data Safety Monitoring Board, Office for Human Research Protections in the U.S. Department of Health and Human Services, the FDA (Food and Drug Administration) and other international regulatory agencies may have access to your data.
Do I have to sign a consent authorization form?
