Effect of lipid lowering on new-onset atrial fibrillation in patients with asymptomatic aortic stenosis: the Simvastatin and Ezetimibe in Aortic Stenosis (SEAS) study.
BACKGROUND Lipid-lowering drugs , particularly statins , have anti-inflammatory and antioxidant properties that may prevent atrial fibrillation ( AF ) . This effect has not been investigated on new-onset AF in asymptomatic patients with aortic stenosis ( AS ) . METHODS Asymptomatic patients with mild-to-moderate AS ( n = 1,421 ) were r and omized ( 1:1 ) to double-blind  simvastatin 40 mg and ezetimibe 10 mg combination or placebo and followed up for a mean of 4.3 years . The primary end point was the time to new-onset AF adjudicated by 12-lead electrocardiogram  at a core laboratory reading center . Secondary outcomes were the correlates of new-onset AF with nonfatal nonhemorrhagic stroke and a combined end point of AS-related events . RESULTS During the course of the study , new-onset AF was detected in 85 ( 6 % ) patients ( 14.2/1,000 person-years of follow-up ) . At baseline , patients who developed AF were , compared with those remaining in sinus rhythm , older and had a higher left ventricular mass index a smaller aortic valve area index . Treatment with simvastatin and ezetimibe was not associated with less new-onset AF ( odds ratio 0.89 [ 95 % CI 0.57 - 1.97 ] , P = .717 ) . In contrast , age ( hazard ratio [ HR ] 1.07 [ 95 % CI 1.05 - 1.10 ] , P < .001 ) and left ventricular mass index ( HR 1.01 [ 95 % CI 1.01 - 1.02 ] , P < .001 ) were independent predictors of new-onset AF . The occurrence of new-onset AF was independently associated with 2-fold higher risk of AS-related outcomes ( HR 1.65 [ 95 % CI 1.02 - 2.66 ] , P = .04 ) and 4-fold higher risk of nonfatal nonhemorrhagic stroke ( HR 4.04 [ 95 % CI 1.18 - 13.82 ] , P = .03 ) . CONCLUSIONS Simvastatin and ezetimibe were not associated with less new-onset AF . Older age and greater left ventricular mass index were independent predictors of AF development . New-onset AF was associated with a worsening of prognosis
