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).
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.
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 (κ = -0.107 P = .02). In the remaining patients, METse overestimated functional capacity measured by ergometry (METse > METsVO2).
Subjective assessment overestimates functional capacity and should not replace objective testing in patients scheduled for lung resection surgery.
代谢当量（MET）是一种生理指标，代表日常生活活动的代谢成本。一个 MET 相当于静息代谢率。MET 可以通过问卷进行估计，也可以通过测量最大摄氧量（VO2max）进行计算。本研究旨在确定术前咨询时估计的 MET（METse）是否与 VO2max 计算得出的 MET（METsVO2）相关。
这是一项针对计划接受肺切除术的患者的回顾性观察研究。根据 2014 年欧洲和美国非心脏手术术前心血管评估指南，在术前咨询中估计 MET。VO2max 在运动实验室中计算。
共有 104 例患者纳入研究，其中 25 例（24%）为女性。平均年龄为 65.1 岁（±9.8）。在 26 例患者（25%）中，METse 分类与 METsVO2 相关（κ= -0.107，P= 0.02）。在其余患者中，METse 高估了通过运动试验测量的功能能力（METse＞METsVO2）。
在计划接受肺切除术的患者中，主观评估高估了功能能力，不应替代客观测试。
