Physical activity, physical fitness and body habitus of patients may be important predictors of outcomes after cardiac surgery. This study sought to quantify physical fitness and determine whether components of fitness enhance the prediction of outcomes in a group of patients undergoing coronary artery bypass grafting.
A group of 200 patients were evaluated prior to coronary artery bypass surgery. A Veterans Specific Activity Questionnaire (VSAQ) measured aerobic capacity. A grip dynamometer assessed strength. Skin-fold thickness was used to calculate percent body fat and lean body mass index. Patients were divided into low risk (0-2.5%) and high risk (>2.5%) groups based on the STS National Cardiac Surgery Database prediction of operative mortality.
Patients with both a high percent body fat and a low VSAQ were at higher risk for at least one serious complication (p<0.05) and a longer postoperative length of stay (p<0.05).
This study suggests: 1) An index of physical fitness can be obtained preoperatively in cardiac surgical patients; 2) This information aids in the prediction of operative risk.
患者的体力活动、体能和体型可能是心脏手术后预后的重要预测指标。本研究旨在量化体能，并确定体能的各个组成部分是否能增强对一组接受冠状动脉搭桥手术患者预后的预测。
对一组200例患者在冠状动脉搭桥手术前进行评估。使用退伍军人特定活动问卷（VSAQ）测量有氧能力。用握力计评估力量。通过皮褶厚度计算体脂百分比和瘦体重指数。根据胸外科医师协会（STS）国家心脏手术数据库对手术死亡率的预测，将患者分为低风险（0 - 2.5%）和高风险（>2.5%）组。
体脂百分比高且VSAQ低的患者发生至少一种严重并发症的风险更高（p<0.05），术后住院时间更长（p<0.05）。
本研究表明：1）心脏手术患者术前可获得体能指标；2）该信息有助于预测手术风险。
