What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests a telemedicine program for people aged 65-80 with both atrial fibrillation and heart failure living in rural China. Village clinics are randomly assigned to offer either standard care or a program that includes a digital health system, a smartwatch for monitoring, group exercise sessions, and personalized education. The goal is to see if this approach improves heart failure risk scores and reduces serious events like stroke or hospitalization over three years.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Digital Intelligent Integrated Management (behavioral intervention including digital system, lifestyle changes, wearable device, and education)
What this could lead to
If successful, this could show that a village doctor-led telemedicine program improves heart failure outcomes and reduces hospitalizations in older rural patients.
What could go wrong
This is a cluster trial in a specific rural setting in China, so results may not apply elsewhere. The intervention is complex and relies on technology and adherence, which may limit effectiveness.

Study facts

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

About 942 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Aug 2026

An estimate. Start dates often move.

Expected to finish

Dec 2029

An estimate. End dates often move.

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.

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

1\. The village clinics need to be willing and able to provide integrated care to their patients with atrial fibrillation; 2. The village doctors from one village clinic serves all AF patients from 3-5 nearby villages; 3. The village doctors are trained to have a fundamental understanding of telemedicine; 4. Patients are eligible for participation if 1)they aged 65-80 years. 2) Electrocardiogram (ECG) confirmation of AF or possession of a diagnostic certificate for AF issued by a specialist. 3) A documented history of HF or a diagnosis of HF based on echocardiography and/or NT-proBNP screening, defined by the presence of typical HF symptoms and/or signs, together with one of the following: reduced left ventricular ejection fraction (HFrEF; LVEF \< 40%), mildly reduced left ventricular ejection fraction (HFmrEF; LVEF 40-49%), or preserved left ventricular ejection fraction with elevated NT-proBNP and structural heart disease changes (HFpEF; LVEF ≥ 50%, meeting at least one of the following criteria: LAV 40 ml/m², E/e' ≥ 15, or TRV \> 2.8 m/s). 4) Management by a village clinic near the participant's place of residence. 5) Ability to understand the study procedures and provide written informed consent. Exclusion Criteria: 1. Expected life expectancy of less than 12 months. 2. Severe renal insufficiency (Ccr \< 30ml/min) or ongoing dialysis treatment. 3. Cardiac insufficiency secondary to correctable causes, including hyperthyroid heart disease, anemic heart disease, or uncorrected congenital heart disease. 4. Indications for pacemaker implantation without having undergone implantation. 5. Chronic obstructive pulmonary disease (COPD) complicated by type II respiratory failure. 6. Special populations, including patients with mental illnesses.
