Does Atorvastatin Prevent Post Operative Atrial Fibrillation After Pulmonary Resection: A Randomized Clinical Study

The incidence of atrial arrhythmia after thoracic, non-cardiac procedures is exceedingly
common and has been reported to occur in between 10-39% of patients. It has been shown to
increase majority morbidity and also delay hospital discharge. Recent studies suggest that
one week of pre-operative atorvastatin may reduce the incidence of post-operative atrial
arrhythmia in patients who undergo cardiac surgery and a multi-institutional study is
currently underway to further examine this concept. However, there are no published
prospective randomized studies to date that have evaluated the effectiveness of atorvastatin
to reduce atrial arrhythmia in patients who undergo thoracic, non-cardiac operations such as
esophagectomy or pulmonary resection. The object of this study is to determine if
atorvastatin reduces the incidence of atrial arrhythmia (atrial fibrillation or flutter)
following non-cardiac thoracic surgery, specifically pulmonary resections.
