<h3>Background</h3> Older patients are increasingly being referred for cardiac surgery, consequently novel prognostic markers which reflect physiological reserve and severity of co-morbid disease now required. Forced Expiratory Volume in one second (FEV₁) is a robust accurate measure pulmonary physiology predicts all-cause mortality, yet the relationship between FEV₁ outcome undergoing surgery unknown. We hypothesised that would predict mortality length hospital stay following surgery. <h3>Methods</h3> In retrospective cohort design, records 2241 consecutive coronary artery bypass grafting and/or valve from 2001 to 2007 were selected regional database linked spirometry database. Generalised linear models association adjusted age, sex, height, body mass index, socioeconomic status, smoking, cardiovascular risk factors, chronic disease, type urgency was compared an established prediction model, EuroSCORE. <h3>Results</h3> Spirometry performed 2082 (93%) whose mean (SD) age 67 (10) years. Median 3-days longer lowest highest quintile FEV_1, 1.35-fold higher (95% CI 1.20 1.52; p&lt;0.001). The OR increased 2.11-fold 1.45-3.08; p&lt;0.001) per SD decrement (800 ml). improved discrimination EuroSCORE mortality. <h3>Conclusions</h3> Reduced strongly in-hospital
