All from the comfort of home
Completely virtual & observational only— no visits, drugs, needles, or medical procedures.

Your study kit shipped at no cost
You’ll receive a kit with medical grade devices and wearables (like a heart monitor, blood pressure cuff, cardiobracelet, etc.) shipped directly to your home at no cost to you.

Personal monthly heart-health report
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.
What will I do?
On most weeks, all study tasks take only a few minutes to complete. You will NOT be asked to take any experimental drugs, undergo any medical procedures, or change your current treatment plan. In other words, this study fits into your routine and is purely observational – you can go about your life as usual while the devices quietly collect data in the background.
Here’s what being involved looks like:
- You’ll wear a small heart monitor seven days out of the quarter
- Use a provided CardioWatch to check your blood pressure and weight about once a week
- Answer a few brief questions on the study app
- With your consent, we will work with you to connect your electronic medical records to the OCORO Heart Study research to help achieve its goal of understanding patterns across heart conditions.
How long will I participate?
It’s up to you. The study will run for up to 5 years, but you decide how long you stay in – whether a few months or a few years.
Every bit of participation helps, and you’re free to withdraw or take a break from participating any time.
Why participate in the OCORO Heart Study?
Help others by sharing your heart journey
Every heartbeat tells a story. By sharing your data, you’re helping researchers see how heart conditions change over time in real life, outside of brief clinic visits. This helps identify unique patterns within heart conditions and how some conditions may relate to one another. We use secure systems, end-to-end encryption, and access controls to protect your information. Please see more details in the FAQs and in our privacy policy.
Join a movement that could help develop more personalized heart treatments in the future.
Your participation helps accelerate research and could lead to smarter tools and treatment development. This is all for a mission to bring us closer to personalized, proactive heart care so that in the future, care fits your life - not the other way around.
Stay in tune with your heart health
Knowledge is power – as a participant, you’ll receive a personal Heart Health Summary each month. See your stats (like heart rate, sleep, blood pressure, etc.) in one easy report that you can share with your doctor.
Join a community of heart heroes
You’re not alone - join others enrolled in the OCORO Heart Study who want to be part of shaping the future of heart research that could help develop more personalized treatments.

Meet Prolaio
We’re a team of cardiologists, nurses, data-scientists, technologists, and other heart health innovators dedicated to building today's real-world heart insights for improving tomorrow's heart care so every patient gets the right care at the right time.
We envision a future where care teams and hospitals are more effective, researchers have greater confidence in their clinical trials, the healthcare system is more efficient, drugs are developed and delivered more efficiently, and patients experience better care and healthier, more fulfilling lives.
Understanding heart conditions
Why it matters
Heart 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. Care teams and researchers need to understand the whole picture to truly improve care. This study is about capturing that invisible time between check-ups. By wearing these devices, you shine a light on how your heart is doing day-to-day, helping find patterns that could help develop more personalized treatments in the future.
Your data is private & secure (HIPAA-compliant)
Meet Dr. Greg Kurio
I’m a practicing pediatric cardiologist with a persistent drive to improve the science and practice of heart care, whether that is through drug development, smarter technology enablement or simply making it easier for our cardiology teams' nurses and doctors to understand patients' journeys.
In 25+ years caring for the youngest patients with heart disease, I have followed those journeys through very high highs and very low lows, but also often through different forms of heart disease. The clinical data reflected in those experiences have historically been hard to track as it resides in different databases [or registries] containing very different medical information (decided upon by different doctors and researchers).
That reality has made the long term picture for patients, especially those with less common disease journeys, far more difficult to see. I envision OCORO, collecting similar data (selected by the same group of medical practitioners) over a longer period of time and following patients through the ups and downs of their heart disease, even if the diagnosis changes, as unlocking greater understanding of heart disease journeys.

FAQs

Participation does not change your current care. For insurance questions specific to your situation, please consult your plan. Your insurance plan will not be contacted based on your participation in OCORO Heart Study.
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 and have an opportunity to ask questions 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
