ABSTRACT
BACKGROUND AND OBJECTIVE:
Metabolic equivalent of task (MET) is a physiological measure that represents the metabolic cost of an activity of daily living. One MET is equivalent to the resting metabolic rate. METs can be estimated by questionnaires or calculated by measuring maximal oxygen uptake (VO2max). The aim of this study is to determine whether METs estimated in the pre-consultation (METse) correlates with METs calculated from VO2max (METsVO2). PATIENTS ANDMETHODS:
Retrospective observational study in patients scheduled for lung resection surgery. The estimation of METs was obtained in the pre-consultation according to the 2014 European and American guidelines for preoperative cardiovascular assessment in non-cardiac surgery. VO2max was calculated in the ergometry laboratory.RESULTS:
A total of 104 patients were included in the study, of whom 25 (24%) were female. The mean age was 65.1 years (±9.8). In 26 patients (25%), the METse classification correlated with METsVO2 (κâ¯=â¯-0.107 Pâ¯=â¯.02). In the remaining patients, METse overestimated functional capacity measured by ergometry (METseâ¯>â¯METsVO2).CONCLUSIONS:
Subjective assessment overestimates functional capacity and should not replace objective testing in patients scheduled for lung resection surgery.Key words
