Trial summary

FFR-guided PCI has been performed in National Taiwan University Hospital(NTUH) for many years. Nevertheless, the method of FFR measurement in NTUH is different from that in literature. In this study, the investigator would like to evaluate the effectiveness and safety of NTUH experience in FFR prospectively. Read more about this study

About this study

Official title: The Safety and Efficacy of Current FFR Measurement in NTUH Health Care System

FFR-guided PCI has been performed in National Taiwan University Hospital(NTUH) for many years. Nevertheless, the method of FFR measurement in NTUH is different from that in literature. In this study, the investigator would like to evaluate the effectiveness and safety of NTUH experience in FFR prospectively. First, the investigator will record any intracoronary (IC) injected adenosine-related complications, such as bradyarrhythmia or chest discomfort. Second, the investigator will follow up on the clinical outcome of the participants for 2 years, record if any target lesion failure, target vessel failure, target vessel-related myocardial infarction, and cardiac death. Finally, left ventricular diastolic pressure, serum pro-brain natriuretic peptide (pro-BNP), and high sensitivity C- reactive protein (hsCRP) will be checked and determined their relationships with the maximum dosage of IC adenosine.

Read the detailed description

FFR has been introduced for the determination of physiological ischemia in the myocardium for many years. Nowadays, FFR-guided PCI is highly recommended for the assessment of physiologic ischemia in intermediate coronary lesions. FFR-guided PCI has been performed in National Taiwan University Hospital(NTUH) for many years. Nevertheless, the method of FFR measurement in NTUH is different from that in literature. In this study, the investigator would like to evaluate the effectiveness and safety of NTUH experience in FFR prospectively. First, the investigator will record any intracoronary (IC) injected adenosine-related complications, such as bradyarrhythmia or chest discomfort. Second, the investigator will follow up on the clinical outcome of the participants for 2 years, record if any target lesion failure, target vessel failure, target vessel-related myocardial infarction, and cardiac death. Finally, left ventricular diastolic pressure, serum pro-brain natriuretic peptide (pro-BNP), and high sensitivity C- reactive protein (hsCRP) will be checked and determined their relationships with the maximum dosage of IC adenosine.

Bradycardia, Dyspnea

What is being measured

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

  1. Adenosine related adverse event

    Including

    1. Bradyarrhythmia including sinus pause and transient AV block
    2. Acute respiratory failure define by respiratory distress which need mechanical ventilator support

    Measured: 24 hours

  2. Major adverse cardiac event (MACE)

    MACE including target lesion failure, target vessel failure, target vessel-related myocardial infarction, and cardiac death

    Measured: 2 year

Secondary outcomes (1)
  1. The relationship between left ventricular diastolic pressure and maximum dosage of IC adenosine

    Determine the correlation of left ventricular diastolic pressure and peak dosage of IC adenosine with FFR protocol in NTUH system

    Measured: 1 hour

Questions about this trial

What is this clinical trial studying?

An observational study of Bradyarrhythmia and Dyspnea, run by National Taiwan University Hospital Hsin-Chu Branch at 1 site in Taiwan.

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 1 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 1 Mar 2021. 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 Taiwan. 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 Chien-Boon Jong, MD (+88635322140, jgboon0407@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Adenosine related adverse event (time frame: 24 hours). The study lists 2 primary outcomes in all. 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 1 Mar 2021.
