About this study

The aim of this study is to determine the diagnostic yield of continuous 7-day Holter ECG for detecting covert paroxysmal atrial fibrillation in patients with recent embolic stroke or transient ischemic attack (TIA) of undetermined cause after completion of a standard clinical work up including an initial 24-hour Holter monitoring.

Read the detailed description

Covert atrial fibrillation (AF) is a relevant potential cause of a recently proposed clinical construct, "Embolic Stroke of Undetermined Source (ESUS)". However, routine post-stroke work up including 24-hour Holter monitoring may fail to detect paroxysmal AF. A recent systematic review has shown an increased AF detection rate with longer monitoring durations. The aim of this study is to evaluate the effectiveness of a novel ambulatory 7-day Holter ECG (EV-201, Parama-Tech inc.) for detecting AF in patients with recent ESUS after completion of a standard clinical examination.

What is being measured

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

  1. Detection of any atrial fibrillation

    Measured: After examination of 7-day Holter monitoring (within 90 days of stroke onset)

Secondary outcomes (5)
  1. Change of antithrombotic drugs

    Measured: After the examination of 7-day Holter monitoring

  2. Any ischemic or hemorrhagic event

    Measured: 365 days after index stroke

  3. Any adverse event related to 7-day Holter monitoring

    Measured: After the examination of 7-day Holter monitoring

  4. Time to detection of atrial fibrillation on 7-day Holter monitoring

    Measured: After the examination of 7-day Holter monitoring

  5. Atrial fibrillation burden

    defined as the total time in atrial fibrillation devided by the total monitored time

    Measured: After the examination of 7-day Holter monitoring

Questions about this trial

What is this clinical trial studying?

An observational study of Stroke, run by National Cerebral and Cardiovascular Center, Japan at 1 site in Japan.

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 4 inclusion and 6 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 2 Dec 2016. 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 Japan. 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?

Contact Yuichi Miyazaki, MD (81-6-6833-5012, ymiyazaki@ncvc.go.jp), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Detection of any atrial fibrillation (time frame: After examination of 7-day Holter monitoring (within 90 days of stroke onset)). 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 NCT02801708, 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 2 Dec 2016.
