Lower cardiac index is associated with lower temporal lobe cerebral blood flow in older adults, independent of prevalent cardiovascular disease.
Hypothesis-generating for cardiac output and temporal lobe perfusion; should not yet change practice in older adults.
Among older adults without stroke, dementia, or heart failure, systemic blood flow correlates with cerebral CBF in the temporal lobe, independently of prevalent CVD, but not CVR.
