An observational study in Heart Failure With Preserved Ejection Fraction (HFpEF), sponsored by Manchester University NHS Foundation Trust. Recruiting at 1 site in United Kingdom. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-10-01.
Sponsored by Manchester University NHS Foundation Trust · Observational
Heart failure with preserved ejection fraction (HFpEF), a certain type of heart failure, occurs when the heart doesn't pump blood around the body properly. It can cause breathlessness, tiredness, and swollen feet or ankles. It is not clear why people develop HFpEF and treatment options are very limited.
TRAITS-HFpEF is a study that aims to understand why people develop HFpEF, identify new tests and treatments, and gain information on the life expectancy of people living with this condition. It will do this by routinely collecting information on people attending a specialised outpatient HFpEF clinic.
HFpEF represents the single largest unmet need in cardiovascular medicine (Butler et al, 2014). The proportion of patients with HFpEF ranges from 22 to 73% of all heart failure patients across all clinical settings, including primary care, hospital care and hospital admission (Ponikowski et al, 2016).
Treatment options in HFpEF are very limited, and several clinical trials have demonstrated neutral results when assessing survival benefit from medical therapy. A common theme for this is the heterogeneity that exists in the HFpEF patient population and non-targeted therapy is inadequate for this diverse population. Patients need to be characterised according to their clinical phenotypes and underlying biological mechanisms in order to provide targeted patient-specific treatment. (Shah et al, 2016)
TRAITS-HFpEF is an observational cohort study that aims to assess the epidemiology, and the association of clinical variables and outcomes of patients with HFpEF. A dedicated specialist HFpEF clinic provides the opportunity to recruit and collect data on a large cohort of patients that can provide insights into different HFpEF phenotypes and their associations and outcomes. This can help direct future research and delivery of specialist care.
All patients attending the HFpEF clinic at Manchester University NHS Foundation Trust (MFT) will be approached. The expectation is to recruit approximately 1,250 patients over a 5-year period. With the patients consent, a blood sample of approximately 10mL will be taken for biobanking to allow measurement of yet to be identified biomarkers, including plasma and DNA. This will be optional for patients. All clinical variables will be documented at the time of the recruitment.
6,331 studies on the registry are indexed under Heart Failure; 1,396 are open to participants now.
This study's planned enrollment of 1,250 is above the median of 200 across 1,983 observational studies indexed under Heart Failure.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Plan to share: Yes — Participants will be asked to provide consent for pseudonymised study data, including, for example, individual patient-level data, scans and any other data collected as part of the study, to be shared for research purposes with investigators or organisations, including independent commercial organisations ('industry'), in the United Kingdom or overseas, including outside of the European Economic Area and in the United States of America. Participant personal details such as name, address, date of birth, contact details will not be shared.
Time frame: Within the life time of the study
Access criteria: Release of data or samples to investigators or organisations requesting access, whether they reside within or outside the UK, will be covered by Data and/or Material Transfer Agreements. The Agreements are legally binding documents that will regulate the use of data and/or samples to ensure that standards are maintained.
Started Aug 2022 (actual). Primary completion is estimated for Oct 2029, 86 months after the start.
Of 793 non-industry observational studies under Heart Failure, half reached primary completion within 45 months of starting (the median), counting those still running; a quarter within 23 and three quarters within 99. This study's planned 86 months is above that.
Counting every sponsor, half of 975 studies reached it within 41 months; a quarter within 23 and three quarters within 89.
