Using health records and testing to study heart failure types
Part of Heart & circulation clinical trials.
This study combines electronic health record data and detailed heart testing to better understand different heart failure types and what treatments may work best for each. It mainly enrolls people with known heart failure, and also some people without heart failure for comparison.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are at least 30 years old.
- You must have a prior heart record diagnosis of heart failure (for the HF group) or no prior HF diagnosis and no loop “water pill” use (for the comparison group).
- If you are in the HFpEF group: your heart ultrasound shows ejection fraction (squeezing strength) of at least 50%.
- If you are in the non-HF group: you do not have lab evidence suggesting heart failure, like high BNP or NT-proBNP (if those tests exist in your chart).
- You can’t have certain other major heart or lung conditions (like specific cardiomyopathies or some types of pulmonary hypertension).
- You must be able to sign consent and not have a life expectancy under 1 year or certain recent major heart events.

Other trials that look related to this one.
This study looks at how “personalized” (precision) treatment planning for heart failure may work, using results from heart imaging (echocardiogram) or a blood test called B-type natriuretic peptide. You may join if you have heart failure and can follow frequent study check-ins.
This study looks at how the heart muscle works in people with a type of heart failure where the heart pumps normally but doesn't fill properly. It aims to understand the cause better, which could lead to new treatments.
This study looks at people with heart failure with preserved ejection fraction (HFpEF) who are treated at a health unit in Portugal. It uses health records, and some people may be asked to do an exercise test to learn more about different types of HFpEF and how to better manage it.
This study uses simple heart tests and blood markers to sort people with chronic heart failure into different risk levels, which may help guide treatment. You may join if you have heart failure symptoms and certain test findings.
This study looks at a type of heart failure where the heart pumps normally but is too stiff to fill properly. It aims to better understand and classify this condition, which may help guide future treatments.
This study is for people with a type of heart failure called HFpEF, where the heart pumps normally but doesn't relax well. It aims to better understand heart failure through advanced testing, and it includes people who are newly diagnosed or have had a recent hospitalization.
