Summary

This observational study will enroll 30,000 adults in Denmark to better understand heart failure with preserved ejection fraction (HFpEF), a condition where the heart pumps normally but is too stiff to fill properly. Researchers will use blood tests, heart imaging, and health records to find early signs of the disease and identify different patient subtypes. No treatments are given; the goal is to improve detection and knowledge.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to: If successful, this study could lead to better ways to detect HFpEF early and identify different types of the disease, helping doctors personalize care.
What could go wrong: This is an observational study, not a treatment trial. It will not test any new drug or therapy, so it cannot directly improve outcomes for participants.
