Study summary

To clarify the predictive effects of uric acid and superoxide dismutase as biomarkers of oxidative stress on atrial fibrillation, and to provide greater value for the diagnosis and prediction of atrial fibrillation. It provides a new idea for the prevention and treatment of atrial fibrillation.

Read the detailed description

In recent years, a growing number of reports have shown the importance of oxidative stress in the pathophysiological mechanism of AF. During oxidative stress, there is an imbalance between the production of pro-oxidant reactive species and the antioxidant defenses of the cell, and excessive oxidation leads to oxidative damage and cell death. Redox processes can lead to atrial fibrosis and cardiac remodeling , suggesting that strategies to address myocardial oxidative stress may constitute a reasonable approach for the treatment of AF. However, few studies have reported the relationship between comprehensive oxidative stress-related biomarkers and AF. The purpose of this study was to illuminate the relationship of several blood markers of oxidative stress with AF and to provide new clues for the prevention and treatment of AF.

Study population

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.

Eligibility 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 () 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 or alanine aminotransferase levels three times higher than normal and estimated \<30 ml/ (min*1.73 m2));
  3. malignant tumors;
  4. missing data of laboratory indicators at baseline.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Groups and cohorts

  • Atrial Fibrillation cohort

    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. The exclusion criteria were as follows: (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; and (4) missing data of laboratory indicators at baseline.

    Diagnostic Test: atrial fibrillation

  • Non-atrial Fibrillation cohort

    Patients attending the Department of Cardiology to rule out atrial fibrillation.The exclusion criteria were as follows: (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; and (4) missing data of laboratory indicators at baseline.

Interventions

  • Diagnostic testatrial fibrillation

    ECG of atrial fibrillation last more than 30 seconds.
