Prediction of Systemic Thromboembolism and Bleeding in Atrial Fibrillation Patients With Factor Xa Inhibitor (Apixaban, Rivaroxaban) by Echocardiographic Parameters: Prospective Observational Study (AF-ECHO Study)

January 13, 2025 updated by: Seong-Mi Park, M.D. Ph.D., Korea University Anam Hospital
Patients taking Factor Xa inhibitors (Apixaban, Rivaroxaban) in atrial fibrillation will be conducted a follow-up investigation on systemic embolism and bleeding events.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

This study aims to evaluate 1) the efficacy and safety of Factor Xa inhibitors (Apixaban, Rivaroxaban) in atrial fibrillation patients who meet the inclusion criteria, and 2) the relationship between systemic embolism and bleeding by tracking and analyzing echocardiographic data, with the goal of developing an AF-ECHO NOAC Score to predict these events. Additionally, we aim to create a predictive model for thromboembolic and bleeding events by observing the occurrence and progression of mitral and tricuspid regurgitation due to atrial remodeling and annular dilation in atrial fibrillation.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

    ① Heart failure

    ② 2. Myocardial infarction (more than 3 months post-event)

    ③ 3. Angina (if PCI was performed, more than 3 months post-procedure)

    ④ 4. Hypertension

    ⑤ 5. Diabetes mellitus

  2. Patients who started taking Factor Xa inhibitors (Apixaban, Rivaroxaban) within the last 12 months and have echocardiographic images taken within 3 months of that time, which are available for analysis.

  4. Individuals who have voluntarily provided written consent to participate in this clinical trial.

Exclusion Criteria

  1. Patients with creatinine clearance (CCr) less than 15 ml/min.
  2. Patients with moderate to severe mitral stenosis.
  3. Patients who have undergone mechanical valve replacement
  4. Patients with a history of clinically significant alcohol or drug abuse.
  5. Patients whom the investigator deems legally or mentally unsuitable for participation in the clinical trial, or those who do not consent to participate in the study.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Patients with chronic AF who have started taking Factor Xa inhibitors.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Primary Outcome MeasureIdentification of risk factors for systemic embolism and bleeding through echocardiography in atrial fibrillation patients taking Factor Xa inhibitors (Apixaban, Rivaroxaban)
Time Frame: From enrollment to the end of treatment at 60 months.
We aim to retrospectively and prospectively assess the risk of systemic embolism and bleeding in Korean patients with atrial fibrillation who are taking oral anticoagulants, specifically Factor Xa inhibitors (Apixaban, Rivaroxaban). Additionally, we will evaluate echocardiographic parameters such as ventricular and atrial function, as well as valvular regurgitation, which are expected to influence the occurrence of embolism and bleeding.
From enrollment to the end of treatment at 60 months.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
