Research questions

We are working to answer important research questions in order to reduce deaths from heart disease.
Can we predict a heart disease diagnosis?

Can we predict different types of heart disease based on measurements, behavior patterns (sleep, diet, activity), and family and medical history?

Can we predict when heart disease will get worse?

Can we predict when specific heart diseases will get worse before someone needs hospitalization, or even before the patient knows something is wrong?

What can people do to improve their heart health?

What habits make heart problems better or worse? Do connected devices improve health? Are there simple changes you could make in your everyday life to improve your heart health?

Who is most at risk of heart disease?

Are there markers from digital devices and wearables that can predict who is most vulnerable to certain heart diseases?

And more!

Our research questions are evolving over time as we learn more about Heart Disease and as the study grows. We have already completed many analyses leading to publications of important findings.

Power in numbers

The Health eHeart study is the biggest of its kind! Because we have so many participants contributing, we have an opportunity to gain novel insights into Heart Disease.

You are the key

You can be our partner in this research! Every participant's contribution is a vital piece of the puzzle.


Our team is working around the clock

Our team includes experts in cardiology, internal medicine, epidemiology, data technology, informatics, social media, and mobile technology. When we're not doing research, we're taking care of patients with heart disease.

FAQs

It's quite easy to register! You sign up with your name, email (a simple way for us to contact you), password, and birth date. Afetr you learn about the study, you'll be asked to sign an electronic consent agreeing to participate and will then start taking surveys from the homepage.

For the main part of the Health eHeart Study, you'll be asked to complete an eVisit—several sections of easy-to-complete surveys and other study activities—every six months. You'll also receive special invitations periodically to participate in other parts of the study (we will only ask for your participation in such a study after you've consented to that specific sub-study). Some examples of specific studies that would require additional consent from you include: mobile apps to track your activity or heart measurements (such as heart rate), sensors to measure things (like ECGs, sleep, blood pressure, weight), collection of DNA, or a visit to one of our study sites (e.g., UCSF) to get specialized cardiovascular testing.

Ideally, we want you to 1) answer the study's health-related questions, 2) check in regulary so we have your most up-to-date information, 3) let us know which additional studies and special invitations you want to accept and participate in, and 4) participate for at least 10 years so we can track how your health changes over time.

You can do each survey online or on your smartphone at your leisure, typically in less then five minutes. Most of them are very basic, but a few require some additional effort. For example, you might have to gather your medications or obtain certain measurements (such as a blood pressure check or a test in your doctor's office or local pharmacy). All of them will help us learn how to prevent and treat heart disease.

You will have an eVisit about every 6 months when we'll ask you to complete a series of surveys. The first one will be the longest in order to collect all the baseline information. You can do the surveys in each eVisit all at once or spread them out over time. And we'll remind you when they are due and when you have new ones to complete. Once you finish a survey, a new one will automatically appear on the homepage until you've completed all of the surveys in that eVisit (and you'll be able to see your progress along the way). In addition, you'll receive occasional special invitations to participate in additional studies or take special surveys, depending on your specific conditions.

Yes. We take this very seriously, and will do everything we can to protect your information and keep it private and secure. Read the Privacy Policy here

No. We will never sell, rent, or lease your information, and we will never voluntarily share your information without your permission.

We will user your information for research. We collect information about your identity (for purposes of creating a secure account), your health, and your behavior in the Health eHeart Study. This information will be used in research analyses and results of these analyses will be presented in scientific conferences and published. These presentations and publications will never show any information that could identify you.

Protection Against Involuntary Disclosure of Your Information: To help us protect your privacy, we have applied for a Certificate of Confidentiality from the United States Department of Health and Human Services (DHHS). This certificate protects against compulsory legal demands, such as court orders and subpoenas, for identifying information or identifying characteristics of a research participant. The Health eHeart Study staff can't be forced to disclose study information that identifies you, even if ordered by a court subpoena, in any federal, state, or local civil, criminal, administrative, legislative, or other proceedings. The researchers will use the certificate to resist any demands for information that would identify you, except to prevent serious harm to yourself or others. We will, in all cases, take the necessary action, including reporting to authorities, to prevent serious harm to yourself or others. Read the Privacy Policy here.
