Help build today's real-world insights for tomorrow's cardiology
Support participation in a national, fully-remote observational study using wearable devices to better understand the natural history of heart conditions relevant to today’s cardiologists and nurses.
Refer a patient
We are conducting a non-interventional, observational study designed to help researchers better understand how chronic cardiovascular conditions behave over time.
Observational only
No study treatment; patients' current care remains under your guidance.
Completely remote
Study-supplied wearables and connected devices are shipped directly to participants with technical support provided by Prolaio, the study sponsor and site.
Longitudinal
Participants contribute data over time from daily life to help researchers understand real-world patterns.
Voluntary
Participants may withdraw at any time.
Who is eligible?
Adults (18+) in the U.S. who have a cardiovascular disease, including but not limited to:
- Heart Failure (HF)
- Hypertension (HTN)
- Hypertrophic Cardiomyopathy (HCM)
- Dilated Cardiomyopathy (DCM)
- Aortic Stenosis (AS)
*Not all eligibility criteria depicted here
What will patients do?
Use the devices, answer in-app questionnaires, and provide access to their electronic health record for research purposes.
Most weeks' tasks take just 5-10 minutes to complete.
How long will patients participate?
The study will be open for up to 5 years.
The length of participation will depend on when the patient joins the study. They are free to withdraw at any time.
What do patients receive?

Secure mobile device with app
Collects data and shares it with the study sponsor
Monthly summary report*
Monthly summary of data collected from a participant that they can choose to share
What happens next?
You’ll never be asked to change a patient’s medications or routines. Your patients are helping deepen understanding of cardiovascular disease for all concerned.
Submit interest
Provide your contact information through our short form to receive information about the study.
Receive materials
After you provide your information, you'll receive a confirmation email with a digital patient referral set of materials. This includes everything you need to easily introduce the study to your patients: a patient-facing informative web destination, digital brochure, and a simple referral document (including an EHR dot‑phrase/AutoText option).
Your patients' journey begins
Once you share the information, your interested patients can enroll directly. Prolaio handles the rest– from device shipping to data collection and patient support.
Why refer patients?
Advance clinical knowledge
Join a large‑scale observational registry that could help inform the understanding of cardiovascular disease.
Patient engagement
Offer your patients an innovative way to stay informed of their own cardiovascular data while contributing to the future understanding of heart conditions. Patients will receive a Patient Summary Report* with their study data for informational purposes only.
Research collaboration
Support your patients’ participation in advancing cardiovascular research.
No treatment changes
Patients continue their usual medications and routines while helping researchers gain deeper insight into cardiovascular disease.
*The monthly summary is provided for informational and for research purposes only. It is not meant to be a medical diagnosis, a guide for treatment, or a replacement for the medical advice from the study participant’s doctor.
