About this study

Official title: Circulating RNAs in Acute Heart Failure

The purpose of this American Heart Association-funded and NIH-funded study is to examine circulating RNAs in the acute CHF setting, how they change with decongestive therapy, and their function in vitro and in vivo.

The investigators are testing the hypothesis that ex-RNA levels change significantly during decongestion therapy and can be used as a marker of those individuals who respond to CHF therapy (in terms of cardiac structure or outcome). Additionally, the translational research design allows the investigators to assay the effects of these RNAs on tissue phenotypes in vitro.

Read the detailed description

Nearly 5 million people in the United States have congestive heart failure (CHF). Although medical therapy such as beta-blockers, angiotensin converting enzyme (ACE) inhibitors, angiotensin-receptor blockers (ARBs) and aldosterone antagonists has improved prognosis, the overall rate of hospital admissions has continued to rise in the last decade and the mortality for patients with symptomatic heart failure remains worse than the majority of cancers in this country. Accordingly, significant opportunities exist for the improvement in outcomes of patients with CHF, both from a morbidity and mortality standpoint. Such opportunities may lie in the outpatient medical management of patients with CHF. Specifically acute CHF represents a particularly underserved area of CHF care.

In this regard, the investigative group and others have demonstrated the utility of extracellular RNAs (short, 20-22 nucleotide RNA molecules stable in circulation in humans) to predict cardiac structural changes and fibrosis in patients post-myocardial infarction with significant changes in cardiac structure. However, little has been done looking at the acute CHF setting. Specific questions include:

  1. What RNAs change in the acute CHF setting, and how do these change over time with diuretic therapy?
  2. Are these changes in RNA functional? That is, do they cause characteristic changes in the heart in vitro and on heart phenotypes in patients?
  3. Do these RNAs predict outcomes in long-term follow-up?

To answer these questions, the investigators will enroll patients who are currently admitted at MGH or BIDMC with acute CHF. The study protocol involves:

  1. Venous blood draw, 40 ml anytime within their hospitalization
  2. Venous blood draw, 40 ml within 48 hours of planned hospital discharge
  3. Venous blood draw, 40 ml at follow-up (within one year of discharge)

Eligible patients (e.g., absence of standard MRI contraindications, GFR > 40ml/min/1.73m2) will be asked pre-discharge or by telephone contact after discharge about coming in for a cardiac MRI study at any point within one year of discharge to examine cardiac structure/function and fibrosis. MRI imaging will be performed by Partners investigators (Dr. Ravi Shah, Dr. Michael Steigner, Dr. Michael Jerosch-Herold) at the 221 Longwood BRIC Imaging Facility (at the Brigham and Women's Hospital, BWH).

Being tested
Cardiac MRI

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Cardiac MRIDiagnostic test

    Cardiac MRI is a test that allows us to look at how the heart muscle works and the amount of scar tissue in your heart. Screening questions will be asked to make sure that patients are not pregnant, and that they have kidney function tests to confirm that IV contrast used (gadolinium) during the MRI is safe for them.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Plasma RNAs levels (rpm by RNAseq) in patients with acute CHF

    Identification of plasma RNAs (absolute reads per million) by RNA sequencing in 1 ml of plasma that are greater than 2 fold increased with p value < 0.05.

    Measured: admission vs. decongestion (up to 2 weeks)

Secondary outcomes (1)
  1. Correlation of plasma RNA levels (rpm by RNAseq) with CMR measurements of ventricular function and in vitro fibroblast proliferation assay.

    Correlation (by PCA regression models) of candidate plasma RNAs (absolute reads per million) identified in the primary outcome with cardiac MRI phenotypes, including extracellular volume fraction or ECV (unit less), LV ejection fraction (percentage), LV systolic volume (ml) and in vitro fibroblast proliferation by MTT assay (absorbance at 490 nm).

    Measured: 6 months

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 9 inclusion and 10 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: under way, not looking for participants, as of the sponsor's last update on 23 Oct 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Plasma RNAs levels (rpm by RNAseq) in patients with acute CHF (time frame: admission vs. decongestion (up to 2 weeks)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03345446, which also lists 1 linked publication.

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 23 Oct 2025.
