Longitudinal differences in cognitive functioning among older adults with and without heart failure

Topic: Risk, prevention and care in population studies
Objective Secondary data analyses were conducted to examine cognitive function and longitudinal cognitive decline among older adults with and without heart failure (HF). Method 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. Results 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. Discussion 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.
Key findings
- Results 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).
- Discussion 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.

How this study scored 62/100
Published in a peer-reviewed journal, and it is a longitudinal study following the same people over time. Scored zero for effect reported and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 36 of the 58 points we could judge it on, which is 62 out of 100.
