Cardiovascular diseases (CVD) are highly prevalent and strongly associated with the risk of falls in the elderly. Falls are associated with impairments in cognition and functional or gait performance; however, little is known about these associations in the elderly population with CVD. In this study, we aimed to clarify the possible associations of physical capacity and functional and cognitive outcomes with the incidence of falls in older adults with CVD. In this comparative study, 72 elderly patients were divided into fallers ( = 24 cases) and non-fallers ( = 48 controls) according to the occurrence of falls within one year. Machine learning techniques were adopted to formulate a classification model and identify the most important variables associated with the risk of falls. Participants with the worst cardiac health classification, older age, the worst cognitive and functional performance, balance and aerobic capacity were prevalent in the case group. The variables of most importance for the machine learning model were VO, dual-task in seconds and the Berg Scale. There was a significant association between cognitive-motor performance and the incidence of falls. Dual-task performance, balance, and aerobic capacity levels were associated with an increased risk of falls, in older adults with CVD, during a year of observation.
心血管疾病(CVD)在老年人中高度流行,且与跌倒风险密切相关。跌倒与认知、功能或步态表现受损有关;然而,在患有CVD的老年人群中,对于这些关联知之甚少。在本研究中,我们旨在阐明身体能力、功能和认知结果与患有CVD的老年人跌倒发生率之间可能存在的关联。在这项比较研究中,根据一年内是否发生跌倒,将72名老年患者分为跌倒组(n = 24例)和非跌倒组(n = 48例对照)。采用机器学习技术构建分类模型,并识别与跌倒风险相关的最重要变量。心脏健康分类最差、年龄较大、认知和功能表现最差、平衡和有氧能力最差的参与者在病例组中更为普遍。对于机器学习模型最重要的变量是VO、双任务完成时间(秒)和伯格平衡量表。认知运动表现与跌倒发生率之间存在显著关联。在一年的观察期内,双任务表现、平衡和有氧能力水平与患有CVD的老年人跌倒风险增加有关。
