What is being measured

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

  1. Percentage of Participants with Non-Obstructive Coronary Artery Disease (CAD)

    Measured: Up to 10 Months

Secondary outcomes (13)
  1. Percentage of Participants With Combined Cardiovascular Risk Factors

    Combined cardiovascular risk factors include: body mass index, smoking habit, hypertension, hyperlipidemia diabetes mellitus, lack of exercise, alcohol intake and family history of early onset cardiovascular disease. Percentage of participants with combined cardiovascular risk factors will be reported.

    Measured: Up to 10 Months

  2. Percentage of Participants With Angina Symptoms

    Measured: Up to 10 months

  3. Percentage of Participants With Pathologic Echocardiography Results

    Measured: Up to 10 Months

  4. Ventricular Wall thickness in Participants With Obstructive and Non-Obstructive Coronary Artery Disease (CAD)

    Mean left ventricular posterior wall thickness (LVPW), interventricular septum (IVS) thickness, other ventricular wall thickness will be assessed for the participants with obstructive and non-obstructive CAD.

    Measured: Up to 10 Months

  5. Left Ventricular End-Diastolic Volume (LVEDV) in Participants With Obstructive and Non-Obstructive Coronary Artery Disease (CAD)

    Measured: Up to 10 Months

  6. Left Ventricular End Diastolic Diameter (LVEDD) in Participants With Obstructive and Non-Obstructive Coronary Artery Disease (CAD)

    Measured: Up to 10 Months

  7. Ventricular Wall Motion in Participants With Obstructive and Non-Obstructive Coronary Artery Disease (CAD)

    Measured: Up to 10 Months

  8. Ratio of Early Trans-Mitral Flow (E) and Late Trans-Mitral Flow by Atrial Contraction (A) in Participants with Obstructive and Non-Obstructive Coronary Artery Disease (CAD)

    Measured: Up to 10 Months

  9. Left Ventricular Ejection Fraction (LVEF) in Participants with Obstructive and Non-Obstructive Coronary Artery Disease (CAD)

    Measured: Up to 10 Months

  10. Percentage of Participants Receiving Anti-ischemic Drugs

    Measured: Up to 10 Months

  11. Percentage of Participants with Myocardial Event Prevention

    Percentage of participants achieving event prevention by antiplatelet agent, anticoagulants, β-blockers, Angiotensin converting enzyme inhibitor (ACEI), Angiotensin receptor blocker (ARB), statin, aldosterone antagonist will be reported.

    Measured: Up to 10 Months

  12. Percentage of Participants With Obstructive and Non-Obstructive Coronary Artery Disease (CAD) Segregated by Age Groups, Genders, Races and Provinces

    Measured: Up to 10 Months

  13. Correlation Coefficient Between Participants With Non-obstructive CAD confirmed by CAG and Clinical Characteristics

    Correlation coefficient between the participants with non-obstructive CAD and different clinical characteristics like demographic characteristics, combined cardiovascular risk factors and angina symptoms will be assessed using logistic regression analysis.

    Measured: Up to 10 Months

Questions about this trial

What is this clinical trial studying?

An observational study of Non-Obstructive Coronary Artery Disease, run by Merck KGaA, Darmstadt, Germany at 1 site in Germany.

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 3 inclusion and 7 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 30 Oct 2018. 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 Germany. 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?

Percentage of Participants with Non-Obstructive Coronary Artery Disease (CAD) (time frame: Up to 10 Months). 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 30 Oct 2018.
