Secondary data analyses were conducted to examine cognitive function and longitudinal cognitive decline among older adults with and without heart failure (HF).
Data from the Advanced Cognitive Training for Independent and Vital Elderly study were used to compare baseline (N = 2,790) and longitudinal (n = 692) changes in memory, reasoning, and speed of processing performance among participants (M age = 73.61, SD = 5.89) who self-reported HF at baseline, developed HF over time, or never reported HF.
At baseline, there were differences in memory and speed of processing with participants who never reported HF performing better than those who reported developing HF over time, and those who reported HF at baseline performing the worst (ps < .05). Longitudinally, participants with self-reported HF at baseline showed declines in reasoning over time.
The results indicate that cognitive difficulties in memory and speed may occur prior to a HF diagnosis, while those with HF may experience steeper declines in reasoning as measured by word series test.
对老年人中有无心力衰竭（HF）患者的认知功能和纵向认知衰退进行二次数据分析。
使用高级认知训练对独立和有活力的老年人研究的数据，比较基线（N=2790）和纵向（n=692）记忆、推理和处理速度表现的变化，参与者（M年龄=73.61，SD=5.89）自我报告在基线时患有 HF，随着时间的推移发展为 HF，或从未报告过 HF。
在基线时，从未报告 HF 的参与者在记忆和处理速度方面存在差异，表现优于随着时间的推移报告发展为 HF 的参与者，而报告基线时患有 HF 的参与者表现最差（p<.05）。纵向来看，基线时自我报告 HF 的参与者在推理方面的表现随着时间的推移而下降。
结果表明，记忆和速度方面的认知困难可能在 HF 诊断之前就已经出现，而 HF 患者在 word series 测试中可能会经历更严重的推理能力下降。
