The purpose of this study is to test whether the drug, atorvastatin, will be able to reduce the rate of return of the abnormal beats after using cardioversion. Atorvastatin is a drug approved by the Food and Drug Administration (FDA) for the treatment of high cholesterol but is not approved for preventing abnormal heartbeats. In addition to lowering cholesterol, the drug reduces inflammation. Inflammation seems to help cause atrial fibrillation, a certain type of abnormal heartbeat. In animals, atorvastatin reduces the risk of this type of abnormal beats, and preliminary data in humans supports an effect of atorvastatin and other similar drugs that have the same action on reducing the risk of this type of abnormal beats. We, the researchers at Emory University, would like to learn if this drug could prevent the return of these abnormal heartbeats.

Primary Outcome Measures:
  • The treatment will be 80 mg/day orally compound for one year [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • A secondary endpoint will be the ability of the intervention to decrease oxidative stress at 30 days [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]

Enrollment: 63
Study Start Date: October 2005
Study Completion Date: October 2009
Primary Completion Date: November 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: Placebo
This will be a double blind, placebo controlled trial compared to Atorvastatin and will be analyzed on an intention to treat basis.
Drug: Atorvastatin
If patients agree to participate, then they will be started on the study drug, 80 mg of Atorvastatin or placebo and followed for recurrence of AF by a variety of surface electrocardiogram techniques. All of which are noninvasive. To insure the medicine is not causing side effects, examinations and blood tests will be done, and to study whether the drug actually affects oxidative stress, blood will be analyzed. The subjects participation ends when AF recurs or after 1 year. This will be a double blind, placebo controlled trial and will be analyzed on an intention to treat basis.
Other Name: Atorvastatin
