Coronary artery diseaseComparison of Frequency of New-Onset Atrial Fibrillation or Flutter in Patients on Statins Versus Not on Statins Presenting With Suspected Acute Coronary Syndrome
Section snippets
Methods and Results
This study was approved by the institutional review board of the Veterans Administration Pittsburgh Healthcare System (Pittsburgh, Pennsylvania). The study population is from an ongoing registry of ACSs and is described elsewhere.2 Briefly, the population consists of patients admitted to monitored beds at the Veterans Administration hospital with suspected ACS/NSTEMI between January 2001 and April 2006.3 Clinical information including laboratory data and patient history were determined by chart
Discussion
Our study shows that use of statins appears to be associated with a significantly lower risk of new-onset AF in patients presenting with suspected ACS/NSTEMI, a finding consistent with previous observations that statins appear to play a beneficial role in the prevention of AF.4, 5, 6, 7 Although this correlation has been assessed in postsurgical patients, after cardioversion in lone AF, and in patients with left ventricular dysfunction, it has not been studied in patients presenting with an
