What this trial studies

This observational study aims to investigate the predictive effects of uric acid and superoxide dismutase as biomarkers of oxidative stress in patients with atrial fibrillation (AF). By analyzing blood markers related to oxidative stress, the study seeks to clarify their relationship with AF and provide insights for better diagnosis and prevention strategies. The research focuses on hospitalized patients diagnosed with AF between January 2018 and December 2020, utilizing data from electrocardiography and Holter monitoring. The findings may contribute to understanding the pathophysiological mechanisms of AF and inform future treatment approaches.

Who should consider this trial

Good fit: Ideal candidates for this study are hospitalized patients diagnosed with atrial fibrillation during the specified time frame.

Not a fit: Patients with acute heart failure, acute myocardial infarction, severe liver or kidney dysfunction, malignant tumors, or missing baseline laboratory data may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the diagnosis and prevention of atrial fibrillation through better understanding of oxidative stress biomarkers.

How similar studies have performed: While there is growing interest in the role of oxidative stress in atrial fibrillation, this specific approach to using comprehensive biomarkers is relatively novel and has not been extensively tested in prior studies.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria: This retrospective study enrolled all hospitalized patients from January 2018 to December 2020 at the Department of Cardiology in The First Affiliated Hospital of Shandong First Medical University. The diagnosis of AF was based on 12-lead electrocardiography (ECG) or 24-hour Holter monitoring, and classification was based on the published 2020 ESC guidelines for the diagnosis and management of AF.

Exclusion Criteria:

1. acute heart failure and acute myocardial infarction;
2. severe liver or kidney dysfunction (with aspartate aminotransferase or alanine aminotransferase levels three times higher than normal and estimated glomerular filtration rate \<30 ml/ (min\*1.73 m2));
3. malignant tumors;
4. missing data of laboratory indicators at baseline.
