Risk assessment for pulmonary resection.
Risk assessment for pulmonary resection must include a preliminary cardiac evaluation. Patients deemed at prohibitive cardiac risk should be evaluated and treated as per American Heart Association/American Society of Cardiology guidelines. Those with low cardiac risk or with optimized treatment can proceed with pulmonary assessment. A systematic measurement of lung carbon monoxide diffusing capacity is recommended. In addition, predicted postoperative forced expiratory volume in 1 second should not be used alone for patient selection because it is not an accurate predictor of complications, particularly in patients with chronic obstructive pulmonary disease. The use of exercise testing should be emphasized. Low-technology tests, such as stair climbing, can be used whenever a formal cardiopulmonary exercise test is not readily available. However, in case of suboptimal performance (ie, <22 m in the stair-climbing test) patients should be referred to cardiopulmonary exercise testing with measurement of Vo(2max) for a better definition of their aerobic reserve. A Vo(2max) less than 10 mL/kg/min (or <35% of predicted) indicates a high risk for major lung resection.
