Change in Inflammatory State in Patients Undergoing Transcatheter Ablation of Atrial Fibrillation (POLICARDIOFA)

September 11, 2023 updated by: Stefano Carugo, Fondazione IRCCS Ca' Granda, Ospedale Maggiore Policlinico
It is a non-pharmacological (biological), spontaneous observational study. The main objective is to evaluate the correlation between inflammation markers and local adiposity, clinical risk factors and their possible variation following an AF ablation procedure

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
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.

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

The study includes the execution of a sample for each time point for the evaluation of inflammation and fibrosis markers identified so far in the literature, such as Interleukin 6, N-terminal propeptide of procollagen type 1 (P1NP), chitinase-3-like protein 1 (YKL-40), tumor necrosis factor (TNF-alpha), GlycA, proprotein convertase subtilisin/kexin type 9 and omega-3 fatty acids.

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

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
Prevalence of subjects with AF undergoing ablation who have a reduction of inflammatory burden following treatment.
Time Frame: One year
Outcome measured through biochemical analyzes conducted on the patient: interleukin 6 (pg/ml), procollagen type 1 N-terminal propeptide (µg/l), chitinase-3-like protein 1(ng/ml), tumor necrosis factor -TNF-alpha - (pg/ml), GlycA (mmol/mol).
One year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Prevalence of subjects with AF undergoing ablation who show improvement in clinical terms and in the arrhythmia recurrence rate.
Time Frame: One year
Identify how many AF patients undergoing ablation have a reduction in related symptoms such as shortness of breath, feeling tired and weakness. The patient will answer an EQ-5D-5L questionnaire for symptom assessment
One year
Relationship between the degree of inflammation and atrial fibrosis and the degree of atrial fibrosis detected by electroanatomical mapping.
Time Frame: One year
Relationship between the degree of inflammation and atrial fibrosis detected through biochemical analyzes conducted on the patient: interleukin 6 (pg/ml), procollagen type 1 N-terminal propeptide (µg/l), chitinase-3-like protein 1(ng/ml), tumor necrosis factor -TNF-alpha - (pg/ml), GlycA (mmol/mol) and the degree of atrial fibrosis detected on mapping electroanatomical (voltage map)
One year

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

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.
