Abstract
Background
The prevalence of depression and/or anxiety disorders is reported to be higher in patients with heart failure (
HF
) than in the general population, and patients with HF also have coexisting cognitive problems. Recently, the development of near‐infrared spectroscopy (
NIRS
) has enabled noninvasive measurements of regional cerebral blood volume and brain activity, in terms of cerebral oxyhemoglobin in the cerebral cortex, with a high time resolution. The aim of the current study was to determine the associations between frontal brain activity and depressive symptoms, anxiety status, and cognitive function in patients with
HF
.
Methods and Results
We measured and compared frontal brain activity determined by
NIRS
during a verbal fluency task in patients with HF (n=35) and control subjects (n=28). The Center for Epidemiologic Studies Depression Scale for assessment of depressive symptoms, State‐Trait Anxiety Inventory for assessment of anxiety status, Mini‐Mental State Examination for assessment of cognitive function, and
NIRS
were simultaneously conducted.
NIRS
showed that frontal brain activity was significantly lower in the
HF
group than in the control subjects (28.5 versus 88.0 mM·mm;
P
<0.001). Next, we examined the associations between frontal brain activity and the findings of Center for Epidemiologic Studies Depression Scale, State‐Trait Anxiety Inventory, Mini‐Mental State Examination, and verbal fluency task. There were significant correlations between frontal brain activity and State‐Trait Anxiety Inventory (
R
=−0.228,
P
=0.046), Mini‐Mental State Examination (
R
=0.414,
P
=0.017), and verbal fluency task (
R
=0.338,
P
=0.007), but not with Center for Epidemiologic Studies Depression Scale (
R
=−0.160,
P
=0.233).
Conclusions
Frontal brain activity assessed by
NIRS
is reduced and is associated with high anxiety status and low cognitive function in patients with
HF
.
