Why the study?
Do Montreal Cognitive Assessment (MoCA) scores differ between community-dwelling adults with systolic versus diastolic heart failure?
Do Montreal Cognitive Assessment (MoCA) scores differ between community-dwelling adults with systolic versus diastolic heart failure?
Patients with systolic heart failure exhibit significantly worse overall cognitive function and specific domain deficits compared to those with diastolic heart failure.

May warrant cognitive screening in systolic HF; hypothesis-generating for subtype effects and needs longitudinal confirmation.
Persons with heart failure (HF) have four times the risk of having cognitive impairment compared with the general population and display different patterns of cognitive impairment. This secondary analysis of a published cross-sectional study of 90 community-dwelling adults examined the Montreal Cognitive Assessment (MoCA) scores and HF differentiated as systolic and diastolic HF. Mean MoCA score was 22.9 (standard deviation±2.31) in persons with systolic HF (n=69) and 24.8 (standard deviation±2.76) in persons with diastolic HF (n=21) with statistically significant mean difference between groups (t=-2.025, P=.030). Independent t test on the eight MoCA domain scores and systolic and diastolic HF indicated significance on visuo-spatial/executive function (P=.026), attention (P=.049), abstraction (P=.014), and delayed recall (P=.048). Findings from this study support the need for including persons with systolic and diastolic HF in future researches on identifying varying cognitive profiles to plan tailored cognitive intervention.
