Key result
Exercise may improve cognitive function in patients with heart failure, potentially through mechanisms such as increased cerebral blood flow and improved cardiovascular function.
Why the study?
Does exercise improve cognitive function in persons with heart failure?
Does exercise improve cognitive function in persons with heart failure?
This review proposes a model suggesting that exercise may improve cognitive function in heart failure patients, primarily through enhanced cerebral blood flow.
Hypothesis-generating for exercise on cognition in HF; prospective RCTs needed before clinical adoption.
More than 6 million Americans have heart failure (HF) and more than 500,000 are diagnosed each year. In addition to its many adverse medical consequences, HF is also a significant risk factor for neurological disorders like Alzheimer's disease and associated with cognitive impairment long prior to the onset of these conditions. Converging bodies of literature suggest cognitive dysfunction in HF may be at least partially modifiable. One key mechanism for cognitive improvement is improved cerebral blood flow, which may be possible with exercise in patients with HF. This brief review provides a model for the likely neurocognitive benefits of exercise in HF and encourages further work in this area.

Galioto et al. (2015) conducted a review in Heart failure. Exercise was evaluated. Exercise may improve cognitive function in patients with heart failure, potentially through mechanisms such as increased cerebral blood flow and improved cardiovascular function.
