Key result
Shorter exercise test distance is linked to postoperative cardiorespiratory complications.
Why the study?
Exercise tests are considered the most reliable preoperative assessment for lung resection candidates but are frequently limited to patients with low predicted postoperative FEV1 and DLCO, and the predictive value of a simple routine exercise test compared to clinical models is unclear.
Does a simple standardised incremental bicycle exercise test predict postoperative cardio-respiratory complications in lung resection candidates compared to a logistic regression model?

Does a simple standardised incremental bicycle exercise test predict postoperative cardio-respiratory complications in lung resection candidates compared to a logistic regression model?
p-value: p=0.001
A simple standardised exercise test predicts postoperative morbidity after lung resection with accuracy comparable to a logistic regression model including age and ppoDLCO.
Varela et al. (2009) conducted an observational in Lung resection candidates (n=103). Standardised incremental bicycle exercise test vs. Logistic regression model (age, BMI, ppoFEV1%, ppoDLCO) was evaluated on Postoperative cardio-respiratory complications (p=0.001). Distance reached during a simple standardised exercise test was significantly lower in patients who developed postoperative cardio-respiratory complications (3498.6m vs 4543.5m, p=0.001).
