Older adults may be subject to prolonged bedrest during hospitalization for acute cardiovascular disease, which can contribute to poor functional outcomes posthospitalization. Our objective was to describe mobility status in hospitalized older adults with acute cardiovascular disease.
Patients aged ≥ 60 years old in the cardiac intensive care unit and cardiovascular ward at a tertiary care academic centre in Montréal, Québec were prospectively enrolled from April 2019 to March 2020. Activity levels were measured with the ActiGraph GT9X Link 3-axis accelerometer (ActiGraph, Pensacola, FL). Sedentary was defined as lying in bed or in a sitting position. Health-related quality of life (HRQOL) was measured with the Short-Form 36 (SF-36) questionnaire by telephone at 1 month posthospitalization. The primary outcome was percentage of sedentary time during hospitalization.
There were 35 patients included in the analysis (75.7 ± 6.9 years old; 45.7% female; 22.9% ischemic heart disease; 20.0% heart failure). Patients spent 91.2% ± 5.5 in a sedentary position during their hospital stay. Mean steps per minute were 1.0 ± 1.2, and mean kcals consumed per day were 116.6 ± 124.5. In the multivariable analysis, a higher percentage of sedentary time and lower steps per minute were each associated with lower total SF-36 scores at 1-month posthospitalization (both < 0.05).
Older adults with acute cardiovascular disease may be sedentary for a large part of their hospital stay. Increased sedentary time is associated with worse self-reported posthospital HRQOL. Future studies are needed to determine whether interventions to increase activity during hospitalization improve posthospital HRQOL and functional outcomes.
老年急性心血管疾病患者住院期间可能需要长期卧床休息，这可能导致出院后功能恢复不佳。我们的目的是描述老年急性心血管疾病住院患者的活动状态。
2019年4月至2020年3月，前瞻性纳入魁北克蒙特利尔一家三级医疗学术中心心脏重症监护病房和心血管内科病房中年龄≥60岁的患者。使用ActiGraph GT9X Link三轴加速度计（ActiGraph，佛罗里达州彭萨科拉）测量活动水平。久坐定义为卧床或坐姿。在出院后1个月通过电话使用简短健康调查问卷（SF-36）测量健康相关生活质量（HRQOL）。主要结局是住院期间久坐时间的百分比。
35例患者纳入分析（年龄75.7±6.9岁；45.7%为女性；22.9%为缺血性心脏病；20.0%为心力衰竭）。患者住院期间91.2%±5.5%的时间处于久坐状态。平均每分钟步数为1.0±1.2步，平均每日消耗热量为116.6±124.5千卡。在多变量分析中，较高的久坐时间百分比和较低的每分钟步数均与出院后1个月时较低的SF-36总分相关（均P<0.05）。
老年急性心血管疾病患者住院期间大部分时间可能处于久坐状态。久坐时间增加与出院后自我报告的HRQOL较差有关。需要进一步研究以确定住院期间增加活动的干预措施是否能改善出院后HRQOL和功能结局。
