Why the study?
Is depressed systemic perfusion associated with cognitive deficits in older adults with heart failure?
Is depressed systemic perfusion associated with cognitive deficits in older adults with heart failure?
Depressed systemic perfusion is associated with cognitive deficits in older adults with heart failure, suggesting a potential mechanism for cognitive impairment in this population.
Should not change HF practice; leaves open whether perfusion optimization affects cognition.
Findings suggest that depressed systemic perfusion is associated with cognitive deficits among patients with heart failure. Research including measures of cardiac function, cerebral perfusion, and cognition will be necessary to clarify the causal nature of the suggested mechanism.
