Atrial Fibrillation and Non-obstructive Coronary Lesions (AF-CAD)

January 6, 2022 updated by: Lukasz Kuzma, Medical University of Bialystok

Is Atrial Fibrillation is Associated With Non-significant Coronary Angiography Findings?

Atrial fibrillation (AF) is the most common cardiac arrhythmia associated with excessive risk of ischemic stroke and heart failure as well as reduced life expectancy. On the other hand, chronic coronary syndromes (CCS) remains the main cause of morbidity and mortality in an aging population. Both disease entities share common risk factors such as hypertension, diabetes and obesity The purpose of the study is to investigate the hypothesis indicating lack of significant coronary lesions in AF vs. sinus rhythm (SR) patients.

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.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Atrial fibrillation (AF) and chronic coronary syndromes (CCS) share common risk factors and both disease entities frequently co-exist. Additionally, AF symptoms may mimic CCS. Objectives: To investigate the hypothesis indicating lack of significant coronary lesions in AF vs. sinus rhythm (SR) patients.

The prevalence of CCS in patients with AF varies from 17% to 47% whereas AF in patients with CCS is much less common, ranging from 0.2% to 5.Patients with AF more often have concomitant CCS as compared with sinus rhythm controls. Additionally, AF is more frequently present in patients with either peripheral- or cerebrovascular artery disease than in non-atherosclerotic individuals We conducted a multi-center retrospective study including consecutive patients referred for elective coronary angiography.

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.

Study Population

We conducted a multi-center retrospective study including consecutive patients referred for elective coronary angiography.

Description

Inclusion Criteria:

  • Coronary angiography

Exclusion Criteria:

  • We excluded patients with acute coronary syndromes (ACS), Tako-tsubo cardiomiopathy and history of ischemic heart disease, as well as those referred for coronary angiography before heart valve surgery. Prior cardiosurgical valve replacement was also the exclusion criterion.

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.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Patients underwent coronary angiography
We reviewed medical notes of patients hospitalized for coronary angiography because of exacerbated angina (recurrent chest pain, classical stable angina, long history of chest pain/angina or other symptoms such as dyspnea). We excluded patients with acute coronary syndromes (ACS), Tako-tsubo cardiomiopathy and history of ischemic heart disease, as well as those referred for coronary angiography before heart valve surgery. Prior cardiosurgical valve replacement was also the exclusion criterion.
Procedure: Coronary angiography

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.
January 1, 2010

Primary Completion (Actual)

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.
