Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 65 to 110 years
  • All sexes
  • No healthy volunteers
  • Older adult

Study population: The survey was designed as a country representative study and was carried out on a sample of Polish residents aged ≥65 years, divided into six age groups of equal size and gender proportion (65-69, 70-74, 75-79, 80-84, 85-89 and 90+ years). The planned size of the research sample was 3,000 subjects (250 subjects for each gender and age group). Research participants were randomly recruited in clusters, in a stratified, proportional draw performed in three stages. The reason for overrepresentation of the oldest age groups was to allow separate analysis of data for older people.

Who may be able to join

  • age ≥ 65 years

Who cannot join

  • age < 65 years

About this study

The aim of this project is to recognize the actual frequency of atrial fibrillation in the Polish population as well as to determine the independent risk factors for the occurrence of its clinically symptomatic and asymptomatic forms

Read the detailed description

The AF Survey is a cross-sectional observational study aimed to assess the prevalence and control of AF and its correlation with CVD risk factors in Poland, based on a representative sample of adults aged 65+. The main aim of the survey is to assess the prevalence, detectability and control of AF, heart failure, vascular diseases, arterial hypertension, stroke, sedentary lifestyle, smoking, lipid disorders, metabolic syndrome, obesity and diabetes, as well as other factors related to CVD risk such as chronic kidney and liver diseases, sleeping disorders, depression and selected psychosocial factors.

The assessment of AF prevalence with use of the monitoring system developed and validated during the first phase of the project, would be composed of a questionnaire, follow-up data sheet, blood pressure (BP) measurements and a blood sample collection.

The survey consists of three visits to subjects' homes (day: 1; 10+/-4 days and 30+/-4 days) and one phone contact one year after first visit and would be performed by trained nurses. The monitoring system would be installed during the first visit for all patients who sign informed consent form and returned at the third visit one month later. The main questionnaire will be completed during the first visit, which included detailed questions about present health status and history of diseases, hospitalizations, and current medications. The socioeconomic part of the questionnaire included questions concerning the personal and family situation, economic status, household structure, leisure activities, hobbies, and social life. During this visit the Geriatric scale of depression evaluation will be given to the subject to be self-completed, and will be collected at the second visit. BP readings would be taken three times during each visit to the patient's home. Anthropometric measurements are taken twice: at visit one and visit three at the end of the ECG monitoring. Blood samples are taken from subjects at the second visit after 10 to 12-hour fasting. The follow-up data sheet would be completed at the initial visit and at the follow-up visit twelve months after inclusion to the survey. The fieldwork is subcontracted to a company specializing in market research projects for the private and public sectors. The transportation of biological material to the Central Laboratory has been subcontracted to a company with expertise in blood sample transport over long distances. Interviewers will be recruited from among professionally active nurses. Most of them will be social nurses working within local communities. All nurses participating in the survey will complete special training prepared for fieldwork executors of the NOMED-AF project.

Questions about this trial

What is this clinical trial studying?

An observational study of Atrial Fibrillation, run by Kardio-Med Silesia at 7 sites in Poland.

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 1 inclusion and 1 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 2 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in Poland. 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?

Atrial fibrillation incidence in general population (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03243474, which also lists 15 linked publications.

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 2 Apr 2019.
