The association between previous statin use and development of atrial fibrillation in patients presenting with acute coronary syndrome

AimsTo examine the association between statin use and the development of atrial fibrillation (AF) in patients presenting with acute coronary syndrome (ACS).MethodsFrom a total of 1000 patients presenting with ACS 241 were on and 759 were not on statin. An AF episode was accepted as endpoint.ResultsThe incidence of AF was less frequent in statin group compared to non-statin group (5% vs 10%, respectively, p = 0.01). Independent predictors of AF were left atrial diameter, use of statin, age, hypertension, previous AF and use of angiotensin converting enzyme inhibitors or angiotensin receptor blockers.ConclusionsIn ACS patients, statin treatment was associated with lower incidence of AF.
