Key result
LVEF and peak VO2, not depression, link to cognitive impairment affecting 56% of CHF patients.
Why the study?
The associations between cognitive impairment, depressive symptoms, and somatic indicators of illness severity in patients with chronic heart failure remain controversial.
Are peak oxygen uptake, left ventricular ejection fraction, and depressive symptoms associated with cognitive impairment in patients with chronic heart failure?
Cross-Sectional (n=55)
Are peak oxygen uptake, left ventricular ejection fraction, and depressive symptoms associated with cognitive impairment in patients with chronic heart failure?
In patients with chronic heart failure, cognitive impairment is common and associated with somatic indicators of illness severity like LVEF and peak oxygen uptake, but not with depressive symptoms.

Hypothesis-generating for cognitive-depression links in CHF; larger prospective studies needed before any screening implications.
Juenger et al. (2011) conducted a cross-sectional in chronic heart failure (n=55). Left ventricular ejection fraction, peak oxygen uptake, and depressive symptoms was evaluated on Cognitive impairment. Left ventricular ejection fraction and peak oxygen uptake, but not depressive symptoms, were associated with cognitive impairment, which was detected in 56% of patients with chronic heart failure.
