Cardiovascular Registry of Atrial Fibrillation (LACROSS)

October 3, 2024 updated by: Brazilian Clinical Research Institute

Cardiovascular Registry of Atrial Fibrillation in Latin America: The LACROSS Study

Follow a representative sample of Latin American patients diagnosed with atrial fibrillation to set data on demographic characteristics, documenting antithrombotic therapy, describe the INR control level of VKA users, discontinuation rates and clinical outcomes, such as stroke, hemorrhage and death

Study Overview

Status

Status

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

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

Patients will be followed 6 months and 1 year after the baseline visit and will be collected data of antithrombotic therapy, laboratory data, discontinuation rates of antithrombotic therapy and clinical outcomes.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Probability Sample

Study Population

Patient with Atrial Fibrilation or Atrial Flutter

Description

Inclusion Criteria:

  • Age > 18 years-old that signed informed consent;
  • Atrial Fibrillation or Atrial Flutter at the time of inclusion documented in source document;
  • If the patient is not in atrial fibrillation or Atrial Flutter rhythm, s/he should have 2 electrographic records, at least 15 days apart between them, with one of them being performed within the last 6 months before enrollment (AF may be documented by 12-lead ECG, Holter monitor-24h);

Exclusion Criteria:

  • Patients who did not agree to participate.
  • Patients without possibility of monitoring for 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.
August 4, 2020

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.
