hree times as many patients with systolic heart failure appear to have memory impairment compared with patients who had diastolic dysfunction, data from a small cohort study showed. In the study of 80 older adults, two-thirds of those with systolic dysfunction had evidence of cognitive impairment -- affecting both their immediate and delayed memory. In contrast, only 21% of those patients with diastolic heart failure had memory-related cognitive impairment, according to a presentation here at the Heart Failure Society of America.
