Poor functional capacity is associated with increased risk of perioperative complications.15Patients unable to perform workloads of 4 METs or greater, such as walking up a hill or climbing 2 or more flights of stairs, have a 2-fold increased risk of perioperative cardiovascular complications compared with those who are able (9.6% vs 5.2%, respectively;P = .04).Among 1396 patients, the quantitative Duke Activity Status Index, derived from a validated questionnaire assessing functional capacity (range, 0-58.2; higher values indicate greater functionality),40was independently associated with death or myocardial infarction in 28 patients (2%) within 30 days of surgery (adjusted OR, 0.91 [95% CI, 0.83-0.99]) for every 3.5 points on the index; however, theabsolute event rates corresponding to the ORs were not available).

功能容量差与围术期并发症的风险增加相关。不能完成≥4MET（如步行上山或爬2级或更多楼梯）工作负荷的患者，围术期心血管并发症的风险是能完成患者的2倍（分别为9.6%和5.2%；P=0.04）。在1396名患者中，量化的杜克活动状况指数（来自有效的评估功能能力的问卷，数值范围0-58.2；更高的值表明功能状态更强）与28名患者（占2%）手术后30天内死亡或心肌梗死独立相关（调整后的OR，0.91[95%CI，0.83-0.99]），指数中每3.5分就有0.91[95% CI，0.83-0.99]；但是，与OR相对应的绝对事件发生率不可用）。
