BACKGROUND
We investigated preoperative physical activity (PA) and sedentary behaviour (SB) in patients scheduled for elective cardiac procedures and compared them with population-based sample of Finnish adults.
METHODS
Cardiac patients (n = 139) undergoing cardiac operations carried a triaxial accelerometer for seven days during the month before the procedure. Patients were categorised into four groups according to the procedure: percutaneous coronary intervention or coronary angiography (PCI-CA), coronary artery bypass grafting (CABG), aortic valve replacement (AVR) and mitral valve surgery (MVS). The raw accelerometer data was analyzed with dedicated algorithms to determine metabolic equivalents (METs, 3.5 mL/kg/min of oxygen consumption) of PA. The intensity of PA was divided into two categories: light (LPA, 1.5-2.9 METs) and moderate-to-vigorous (MVPA, ≥ 3.0 METs), while SB represented intensity < 1.5 MET without movements. SB and PA were described as daily means and accumulation from different bout lengths. Daily standing, steps and mean and peak MET-values were calculated. The results were compared between the patient groups and against the reference group from a population-based study FinFit2017.
RESULTS
Cardiac patients had fewer daily steps than the FinFit population (p = 0.01), and less SB accumulating from < 20 min bouts (p = 0.002) but more from 20 to 60 min bouts (p = 0.002). Particularly, CABG group had less daily MVPA (p = 0.002) and MVPA accumulating from > 10 min bouts (p < 0.001) than the FinFit population.
CONCLUSIONS
We found large differences in PA and SB between the patient groups and the FitFit population, CABG group having the worst activity profile. Also, the variation within the patient groups was wide, which should be considered to individualise the rehabilitation programs postoperatively. Trial registration clinicaltrials.gov (NCT03470246).

背景
我们调查了计划进行择期心脏手术患者的术前身体活动（PA）和久坐行为（SB），并将他们与芬兰成年人的基于人群的样本进行比较。
方法
接受心脏手术的心脏患者（n = 139）在手术前一个月内佩戴三轴加速度计7天。根据手术将患者分为四组：经皮冠状动脉介入治疗或冠状动脉造影（PCI-CA）、冠状动脉旁路移植术（CABG）、主动脉瓣置换术（AVR）和二尖瓣手术（MVS）。使用专用算法分析原始加速度计数据，以确定PA的代谢当量（METs，耗氧量3.5 mL/kg/min）。PA强度分为两类：轻度（LPA，1.5-2.9 METs）和中度至剧烈（MVPA，≥3.0 METs），而SB表示强度<1.5 MET且无运动。SB和PA以每日平均值和不同发作时长的累积量来描述。计算每日站立时间、步数以及平均和峰值MET值。将患者组之间的结果与基于人群的研究FinFit2017中的参考组进行比较。
结果
心脏患者的每日步数少于FinFit人群（p = 0.01），<20分钟发作累积的SB较少（p = 0.002），但20至60分钟发作累积的SB较多（p = 0.002）。特别是，CABG组的每日MVPA（p = 0.002）以及>10分钟发作累积的MVPA（p <0.001）均少于FinFit人群。
结论
我们发现患者组与FitFit人群之间在PA和SB方面存在很大差异，CABG组的活动情况最差。此外，患者组内的差异也很大，术后康复计划应考虑个性化。试验注册 clinicaltrials.gov（NCT03470246）。于2018年3月19日注册，https://clinicaltrials.gov/ct2/show/NCT03470246。
