About this study

Official title: Clinical Significance of Stress-MRI Evaluation of Right Coronary Artery Chronic Total Occlusion Recanalization Efficacy in Patients With Coronary Artery Disease.

The hypothesis of this study is that Stress-MRI is a clinically significant method of myocardial perfusion assessment after coronary angioplasty with stenting of right coronary artery (RCA) chronic total occlusion (CTO) is performed.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CTO coronary angioplastyProcedure or surgery

    A standard endovascular procedure is carried out under local anesthesia and under fluoroscopic control. Recanalisation of coronary artery CTO is performed by the hydrophilic coronary wire, using the most appropriate technique. Then balloon angioplasty of target lesion is provided. After the angiographic control coronary stent is implanted. After coronary wire removing control angiographic study is provided. Medical therapy includes aspirin(acid acetylsalicylic) 125 - 300 mg/d and plavix(clopidogrel) in dose 300-600 mg prescription before the procedure and heparin (heparin sodium) injection during the procedure(5000 U iv). After the procedure aspirin(acid acetylsalicylic) in dose 100 mg/d within long period should be prescribed in all the patients, and plavix(clopidogrel) in dose 75/d should be prescribed within 12 months.

What is being measured

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

  1. Stress-MRI evaluation

    High risk of myocardium ischemia according to stress-MRI data (perfusion defect in 2 or more segments in the area of interest)

    Measured: Within 2 and 12 month after hospitalization

Secondary outcomes (3)
  1. Clinical assessment

    Dynamical assessment of stable angina FC (CCS) and dyspnea FC (NYHA)

    Measured: Within 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12 moths after hospitalization

  2. Stress-MRI evaluation (2)

    Dynamics of perfusion in myocardium scar tissue according to stress-MRI data

    Measured: Within 2 and 12 month after hospitalization

  3. Major adverse cardiac and cerebrovascular events (MACCE)

    Major adverse cardiac and cerebrovascular events (MACCE) including: All-cause mortality, Myocardial infarction, Stroke, Stent thrombosis, Clinically indicated Target lesion revascularization, Any target lesion revascularization, Any target vessel revascularization.

    Measured: During 1 year after first stress-MRI assessment

Questions about this trial

What is this clinical trial studying?

A study testing CTO coronary angioplasty, Optimal medicamentous treatment and Stress-MRI in people with Ischemic Heart Disease and Coronary Atherosclerosis, run by Meshalkin Research Institute of Pathology of Circulation at 1 site in Russia.

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 5 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: finished, as of the sponsor's last update on 17 May 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 Russia. 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?

Stress-MRI evaluation (time frame: Within 2 and 12 month after hospitalization). 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 17 May 2016.
