The OCORO Heart Study is a national, observational study designed to help researchers better understand how heart conditions behave over time - whether they are stable or changing - as well as the use of digital health tools.

Inform research understanding
Your data may help improve understanding of heart conditions.

Participate from home
Completely virtual & observational only— no visits, drugs, needles, or medical procedures.

Study kit provided
Digital health devices for research shipped at no cost.

Personal monthly insights*
Summary of data collected from you during the research that you can choose to share with your doctor.
*The monthly summary is provided for informational and for research purposes only. It is not a diagnostic report, it does not constitute medical advice, and it is provided for retrospective review. This report is not a guide for treatment or as a replacement for your doctor’s advice.
Who can join?
Adults (18+) in the U.S. who have a cardiovascular disease, such as:
- Heart Failure (HF)
- Hypertension (HTN)
- Hypertrophic Cardiomyopathy (HCM)
- Dilated Cardiomyopathy (DCM)
- Aortic Stenosis (AS)
What will I do?
Use the devices, answer in-app questionnaires, and provide access to your electronic health record for research purposes.
How long will I participate?
The study will be open for up to 5 years.
The length of your participation will depend on when you join the study. You are free to withdraw at any time.
Why participate in the OCORO Heart Study?
Share your experience, make a difference
By participating, your data may help researchers understand how heart conditions behave over time- whether they are stable or changing.
Become a part of a movement toward precision cardiology
Your participation may help researchers build smart algorithms that can make sense of complex health data in less time and with as little disruption to daily living as possible.
Get connected, stay informed
As part of participation, every month you will receive a summary of the data collected (e.g., heart rate, respiratory rate, weight, blood pressure, activity, and sleep) from you during the study that you can choose to share with your doctor.

To transform real-world heart data into faster discovery today and precision care for functional cures tomorrow. A world where heart care is more personalized and proactive.
Understanding heart conditions
Why it matters
Cardiovascular disease is the leading cause of death in the U.S., yet most care still relies on short, in-person check-ins spaced months apart. What happens in between is often invisible. By participating in this study, you may help researchers better understand how heart conditions behave over time.
Data Privacy & Ethics
This study is approved by an independent Institutional Review Board. We take steps to protect your confidential information whenever possible and your personal information is never sold. Participation is voluntary and unpaid. Leaving the study will not affect your current medical care.

About the OCORO Heart Study
An at-home, observational study using wearable sensors and secure digital tools to learn how everyday heart health changes over time. No drugs or medical procedures.
To better understand the natural course of common heart conditions using real-life data.
Prolaio is the study sponsor. This research is being overseen by WCG, an independent ethics board (IRB) that reviews and oversees the research.
IRB #20253114
The overall project may run about 5 years and enroll up to 5,000 people. Your own participation may be months to years, and you can stop anytime.
Eligibility & getting started
You’ll answer an eligibility check online. If you are eligible, you’ll see an electronic informed consent form (e-consent) explaining details before you decide.
Currently we’re only enrolling adults (18+) living in the U.S. This may change in the future.
No. The form just lets us contact you with information and next steps. You choose whether to proceed.
What participation is like
Once you receive your study kit, you use the devices to:
- Wear an ECG patch for 7 days every 90 days
- Wear a wrist-based health monitor continuously as much as possible
- Use a blood pressure cuff and weight scale about once per week
- Answer health questionnaires on a study-provided phone
- Share your medical history and health records with the research team
No study drugs, no medical procedures, no required clinic visits, and no changes to your current care due to the study.
Most tasks are brief. In short, this remote study does not require much time out of your regular daily life to participate.
Your monthly heart-health summary report
Every month, you get a summary of data collected from you from your study-provided devices (e.g., heart rate, respiratory rate, weight, blood pressure, activity, and sleep)
No. The monthly summary is provided for informational and for research purposes only. It is a summary of data collected from you during the study. It is not a diagnosis or medical advice. This report is not a guide for treatment nor is it a replacement for your doctor’s advice, although you are free to share the summary with your own doctor if you wish.
Yes, sharing with your doctor and any members of your care team is up to you.
Tools & data
Commercially available devices (e.g., ECG patches, PPG bracelets, BP cuffs) will be provided to you.
Participants will be provided the locked mobile device needed to relay collected data but will need to have either reliable cellular signal or internet connection. We’ll confirm specifics during eligibility determination.
Data points, like heart rate, activity, sleep, and survey answers. You will link your health records to provide more context.
