Comparison of Serum Selenium Levels Between Patients with Newly Diagnosed Atrial Fibrillation and Normal Controls
Biol Trace Elem Res. 2022 May 9. doi: 10.1007/s12011-022-03281-9. Online ahead of print.ABSTRACTAtrial fibrillation (AF) is the most common sustained dysrhythmia in the elderly population. It is estimated to affect more than 30 million people worldwide. AF occurs when abnormal electrical impulses start to activate in the atria and override the heart's natural pacemaker, which can no longer control the heart's rhythm. Since atrial contractility is impaired in AF, blood flow in the atria becomes stasis over time and causes thrombus formation. This thrombus causes the risk of embolism and causes complications such as stroke. ...

Predictors of Postoperative Atrial Fibrillation after Coronary Artery Bypass Grafting: A Prospective Cohort Study
ConclusionThere are a wide range of significant epidemiological, clinical, and operative predictors for the development of post-CABG AF including older age, female gender, large LA diameter, higher CHA2DS2-VASc score, valve replacement and postoperative inotropic support. Nevertheless, further large-scale studies are still needed to confirm our findings.

Low serum potassium levels are associated with the risk of atrial fibrillation.
CONCLUSION: We found that low serum potassium levels of less than 3.5 mmol/l are associted with increased risk of AF. PMID: 32723154 [PubMed - as supplied by publisher]
