What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looked at whether taking extra ultrasound images during a standard stress echocardiogram can help doctors figure out if chest pain or shortness of breath is caused by a stiff heart (heart failure with preserved ejection fraction, or HFpEF). Researchers enrolled 30 people aged 50 and older who were already scheduled for a stress echo. They compared the extra images and a risk score to standard care to see if it improved diagnosis.

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 could improve how doctors diagnose stiff heart (HFpEF) using a simple stress echo, reducing the need for more invasive tests.
What could go wrong
This is a small, completed study (30 people) focused on diagnosis, not treatment. The results may not apply to everyone, and the added images might not clearly improve diagnosis.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

Finished

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

50 years and older

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Clinically indicated exercise stress echo for the evaluation of exertional dyspnea or chest pain * Age ≥50 years Exclusion Criteria: * Known history of HFpEF * LVEF \<50% on baseline echo study * History of hypertrophic cardiomyopathy, amyloidosis, or pulmonary arterial hypertension, severe right ventricular dysfunction and severe valvular disease based on chart review or baseline echo study * History of organ transplant (heart, kidney, liver, lungs) * Severe pulmonary disease requiring ambulatory oxygen therapy * End-stage renal disease requiring long-term renal replacement therapy * Decompensated liver disease * Conditions that prevent accurate assessment of E/e' ratio (mitral prosthetic valve, severe mitral annular calcification) * Plan to use echo contrast agent during stress study (i.e. contrast agent needed for baseline study) * Patients from outside Duke health system with no plan for long-term care at Duke
