Research Objectives:

① Main objective: To establish a multidisciplinary assisted diagnosis and treatment model for patients at high risk of cardioembolic stroke, manage and collect the diagnosis, treatment and prognosis data of patients.

② Secondary objective: To investigate the improvement of cardioembolic stroke, cardiovascular complex events, recurrent stroke and all-cause mortality risk, quality of life, and cardiac function between the "multidisciplinary assisted treatment model" group and the "conventional treatment model group". The routine diagnosis and treatment mode can match the patients who did not adopt the "multidisciplinary assisted diagnosis and treatment mode" in the same period.

Type of design: A prospective, observational, real-world study. No fixed diagnosis and treatment plan was established in advance, and only a multidisciplinary assisted diagnosis and treatment model was established. All treatment choices were made by clinicians according to the expert consensus of relevant textbooks and clinical guidelines, and according to the patient's condition.

Subjects: From September 2022 to September 2023, high-risk patients with cardioembolic stroke were collected from the Second Affiliated Hospital of Nanchang University and sub-centers of hospitals at all levels in Jiangxi Province.

Study Title: A real-world registry of multidisciplinary collaborative diagnosis and treatment models for cardioembolic stroke

Research Objectives:

① Main objective: To establish a multidisciplinary assisted diagnosis and treatment model for patients at high risk of cardioembolic stroke, manage and collect the diagnosis, treatment and prognosis data of patients.

② Secondary objective: To investigate the improvement of cardioembolic stroke, cardiovascular complex events, recurrent stroke and all-cause mortality risk, quality of life, and cardiac function between the "multidisciplinary assisted treatment model" group and the "conventional treatment model group". The routine diagnosis and treatment mode can match the patients who did not adopt the "multidisciplinary assisted diagnosis and treatment mode" in the same period.

Type of design: A prospective, observational, real-world study. No fixed diagnosis and treatment plan was established in advance, and only a multidisciplinary assisted diagnosis and treatment model was established. All treatment choices were made by clinicians according to the expert consensus of relevant textbooks and clinical guidelines, and according to the patient's condition.

Subjects: From September 2022 to September 2023, high-risk patients with cardioembolic stroke were collected from the Second Affiliated Hospital of Nanchang University and sub-centers of hospitals at all levels in Jiangxi Province.

Multidisciplinary assisted care mode group: Patients who agreed to and accepted the recommendation of multidisciplinary assisted care mode were enrolled in the multidisciplinary assisted care mode group. These patients would undergo further stroke (primary/secondary) prevention intervention.

Those who received any of the following treatments, as recommended by the standard medical procedure, were considered to have received the standard medical treatment; otherwise, they were not.

  1. Surgical procedures: left atrial appendage ligation, left atrial appendage clip, valve repair or replacement, etc.
  2. Medical procedures: atrial fibrillation radiofrequency ablation, valvular closure, left atrial appendage closure, etc.
  3. Anticoagulant drug therapy: standardized anticoagulant drug therapy.

Routine treatment mode group: Patients who did not agree to enter the multidisciplinary treatment mode were automatically entered into the routine treatment mode group.

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 3 inclusion and 3 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: status not confirmed, as of the sponsor's last update on 12 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. 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?

Results are not available in the source record.

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?

Composite end point of cardiovascular and cerebrovascular events (time frame: 1.5 years). 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 NCT05498909, which also lists 7 linked publications.

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 12 Aug 2022.
