1 New-Onset Postoperative Atrial Fibrillation and Long-Term Survival After Aortic Valve Replacement Surgery  Giovanni Filardo, PhD, MPH, Cody Hamilton, PhD, Baron Hamman, MD, Robert F. Hebeler, MD, John Adams, MPH, Paul Grayburn, MD  The Annals of Thoracic Surgery  Volume 90, Issue 2, Pages (August 2010) DOI: /j.athoracsur Copyright © 2010 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 Unadjusted (Kaplan-Meier) curves depicting the effect of new-onset postoperative atrial fibrillation on survival in patients who underwent aortic valve replacement surgery and survived past the day of surgery at Baylor University Medical Center (Dallas, TX) United States between January 1997 and December (Afib = patient with new-onset postoperative atrial fibrillation; No Afib = patient without new-onset postoperative atrial fibrillation.)

3 Fig 2 Adjusted (proportional hazard model) curves and 95% confidence intervals depicting the effect of new-onset postoperative AF on survival in patients who underwent aortic valve replacement surgery and survived past the day of surgery at Baylor University Medical Center (Dallas, TX) United States between January 1997 and December The propensity adjusted model includes the following risk factors: age, gender, body surface area, race, diabetes, preoperative renal failure, preoperative creatinine level, chronic lung disease, hypertension, peripheral vascular disease, cerebrovascular disease, endocarditis, smoking status, congestive heart failure, previous revascularization procedure (percutaneous coronary intervention or CABG), previous valve surgery, myocardial infarction timing (time since myocardial infarction), ejection fraction, left main disease, urgency of operation (elective or nonelective), and concomitant procedure (CABG). For the purposes of the adjusted curves, all factors are set to their mean values. (Afib = patient with new-onset postoperative AF; No Afib = Patient without new-onset postoperative atrial fibrillation; AF = atrial fibrillation; CABG = coronary artery bypass grafting.)
