Results of a simple exercise test performed routinely to predict postoperative morbidity after anatomical lung resection☆☆☆

Exercise tests are considered the most reliable ones for the preoperative workup of lung resection candidates but frequently are indicated only in cases with low predicted postoperative forced expiratory volume in 1s (FEV1) and carbon monoxide diffusing capacity (DLCO). The aim of this investigation is to evaluate if a simple, standardised incremental bicycle exercise test routinely performed in patients considered operable is predictive of postoperative cardio-respiratory complication and if its performance is comparable to a logistic regression model including frequently cited clinical predictive variables.
