Trial summary

To evaluate the long-term outcome of chronic total occlusion (CTO) patients underwent contemporary percutaneous coronary intervention (PCI) techniques, we design this single-center, large-sample, prospective registry with five-year clinical follow-up, based on the intravascular ultrasound (IVUS) finding.

About this study

Official title: Contemporary Chronic Total Occlusion Percutaneous Coronary Intervention Registry From Insight of Intravascular Ultrasound in Fuwai Hospital

To evaluate the long-term outcome of chronic total occlusion (CTO) patients underwent contemporary percutaneous coronary intervention (PCI) techniques, we design this single-center, large-sample, prospective registry with five-year clinical follow-up, based on the intravascular ultrasound (IVUS) finding.

Read the detailed description

The study plan to include the patients with a CTO lesion in one of the three main epicardial coronary artery (diameter more than 2.5 mm) as the only target lesion. The CTO lesion is defined as 0 grade of thrombolysis in myocardial infarction (TIMI) flow with evidence of occlusion duration more than 3 months. All the PCI procedure will be performed by a group of certified operators in Fuwai Hospital, Beijing, China. All patients evaluate IVUS with automatic pullback (Opticross, Boston Scientific, US) performed after wire crossing. All the included patients are planned for five-year follow-up.

What is being measured

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

  1. Target vessel revascularization

    Any ischemic driven revascularization of the target vessel

    Measured: 5-year follow-up after index PCI

Secondary outcomes (5)
  1. All-cause death

    Any cause of death

    Measured: Within the first 1 month after PCI and during the 5-year follow-up

  2. Cardiac death

    Cardiac death

    Measured: Within the first 1 month after PCI and during the 5-year follow-up

  3. Myocardial infarction

    Any myocardial infarction including perioperative MI

    Measured: Within the first 1 month after PCI and during the 5-year follow-up

  4. Stroke

    Ischemic or hemorrhagic stroke

    Measured: Within the first 1 month after PCI and during the 5-year follow-up

  5. Major adverse cardiac and cerebrovascular events (MACCE)

    Including all-cause death, myocardial infarction, stroke or any target vessel revascularization

    Measured: Within the first 1 month after PCI and during the 5-year follow-up

Questions about this trial

What is this clinical trial studying?

An observational study of Coronary Heart Disease and Chronic Total Occlusion of Coronary Artery, run by China National Center for Cardiovascular Diseases at 1 site in China.

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 6 inclusion and 5 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 8 Feb 2023. 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?

Target vessel revascularization (time frame: 5-year follow-up after index PCI). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 8 Feb 2023.
