About this study

To examine the changes in left ventricular (LV) global longitudinal strain (GLS), using two-dimensional speckle tracking analysis, after left anterior descending (LAD) unroofing, in myocardial bridges (MBs) refractory to optimal medical therapy (OMT).

Read the detailed description

The present study is enrolling all the MBs-patients who underwent angina surgical relief or medical treatment at the "Ospedali Riuniti" of Ancona, Italy, and the "University Hospital" of Chieti, Italy. All the participants will be examined utilizing echocardiography before and after the treatment. The two-dimensional speckle-tracking analysis will be performed with an off-line dedicated software from the apical 4-chambers-view. All the unroofing procedures will be performed under cardiopulmonary bypass.

Being tested
Surgical unroofing of muscle-briged coronary artery

What is being measured

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

  1. Improvement of myocardial function and contractility

    The increment of global longitudinal strain analysis, from pre treatment values, as assessed by speckle-traking echocardiography

    Measured: 1 to 6 month after the procedure/treatment optimizzation

Secondary outcomes (2)
  1. Angina relief after surgical treatment

    Defined as the reduction of CCS-Angina Scale, assessed by physicians, from grade I (ordinary physical activity does not cause angina, such as walking and climbing stairs) to grade IV (inability to carry on any physical activity without discomfort, anginal syndrome may be present at rest). The scale comprises 4 degrees in increasing order of angina severity.

    Measured: 1-month

  2. Improvement in quality of life

    Defined as the score increment, from 0 to 100 of the SAQ-7 questionnaire. The SAQ quantifies patients' physical limitations caused by angina, the frequency of and recent changes in their symptomstheir satisfaction with treatment, and the degree to which they perceive their disease to affect their quality of life. The questionnaire provides 7 different items with 6 different multiple choices. Each scale is transformed to a score of 0 to 100, where higher scores indicate better function (eg, less physical limitation, less angina, and better quality of life).

    Measured: 1-month

Questions about this trial

What is this clinical trial studying?

An observational study of Myocardial Bridge of Coronary Artery, run by ITAB - Institute for Advanced Biomedical Technologies at 1 site in Italy.

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 1 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: finished, as of the sponsor's last update on 29 Dec 2020. 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 Italy. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Improvement of myocardial function and contractility (time frame: 1 to 6 month after the procedure/treatment optimizzation). 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 NCT04082546, which also lists 5 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 29 Dec 2020.
