Fish Oil Versus Statins Versus Placebos in Reducing Atrial Fibrillation in Patients Undergoing Thoracic Surgery for Lung Cancer

The goal of this clinical research study is to learn if Lipitor (atorvastatin) or fish oil supplements can help to control side effects of the heart that are commonly seen after lung surgery (such as irregular heartbeat). Researchers also want to learn if one of these drugs is more effective than the other at controlling side effects.
