Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 30 years and older
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: Adults over 30 years of age.

Who may be able to join

  • HFpEF criteria
  • Age ≥30 years.
  • Left ventricular ejection fraction ≥50% measured by echocardiography, CMR or MUGA (measured within one year + clinical stability)
  • Definition of HFpEF: signs and/or symptoms of HF, NYHA functional class II-IV, and at least one of the following:
  • Elevated BNP (≥75 pg/ml in sinus rhythm or ≥225 pg/ml in atrial fibrillation/flutter) or NTproBNP (≥225 pg/ml in sinus rhythm or ≥675 in atrial fibrillation/flutter) at baseline. Choice of BNP or NTproBNP is based on availability at each clinical center.
  • Prior HF hospitalization (primary reason for the hospitalization is HF with elevated natriuretic peptide levels [using the thresholds listed above], requiring IV diuresis for HF, or pulmonary edema or pulmonary vascular congestion on chest radiography).

  • Previously documented elevated pulmonary capillary wedge pressure (PCWP) at rest (≥15 mmHg) or during exercise (≥25 mmHg for supine exercise or PCWP/cardiac output ratio ≥2 mmHg/L/min for upright exercise).

Who cannot join

  • 1. Inadequate echo or fluoroscopic images.
  • 2. Neck anatomy unfavorable for jugular venous cannulation
  • 3. Therapy with direct oral anticoagulants without cessation for a period (age, renal function, and agent specific) deemed adequate to normalize coagulation according to local clinical guidelines.

About this study

Official title: Myocardial Mechanisms in Heart Failure With Preserved Ejection Fraction (MM-HFpEF) A HeartShare Clinical Study

The purpose of this study is to identify changes in heart tissue structure and biological function in patients with heart failure by performing an endomyocardial biopsy (EMB or heart biopsy) during a right heart catheterization (RHC). The ultimate goal is to use this information to develop new treatments for heart failure.

Questions about this trial

What is this clinical trial studying?

An observational study of Heart Failure and Heart Failure With Preserved Ejection Fraction, run by Northwestern University at 6 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 15 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 29 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Laura Alagna (312-695-6765, heartsharestudy@northwestern.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of participants with Heart Failure with Preserved Ejection Fraction (HFpEF) (time frame: Up to 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Sep 2026.
