1 Pulmonary Function Tests Overestimate Chronic Pulmonary Disease in Patients With Severe Aortic Stenosis  Mitchell J. Magee, MD, Morley A. Herbert, PhD, Karen L. Roper, PhD, Elizabeth Holper, MD, Todd M. Dewey, MD, Tricia Snelus, BA, Michael J. Mack, MD  The Annals of Thoracic Surgery  Volume 96, Issue 4, Pages (October 2013) DOI: /j.athoracsur Copyright © 2013 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 Study flow showing patients with COPD divided into three groups based on preoperative PFTs who had repeat testing 6 to 12 months after AVR. (AVR = aortic valve replacement; COPD = chronic obstructive pulmonary disease; PFTs = pulmonary functions tests.)

3 Fig 2 Survival curves by preoperative COPD severity classification. (COPD = chronic obstructive pulmonary disease; mod = moderate.) The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2013 The Society of Thoracic Surgeons Terms and Conditions

4 Fig 3 Changes in COPD severity class after surgery compared with preoperative classification. (COPD = chronic obstructive pulmonary disease; mod = moderate; Preop = preoperative.)

5 Fig 4 Correlation between decreased BNP values and improved pulmonary function. (BNP = b-type natriuretic peptide; FEV1 = forced expiratory volume in 1 second; postop = postoperative; preop = preoperative.)
