Higher fatigue correlated with
poorer physical health. Our findings
are consistent with previous study
results that showed an association
between fatigue and restrictions in
physical activity and limitations in
self-care.7,16,17 Additionally, fatigue in
older women with HF was related
more to other concurrent physical
symptoms than to psychological factors.
4 Investigators examined plausible
explanations that link fatigue with
higher functional limitations and identified
impaired peripheral circulatory
perfusion with reduced oxygen delivery
and impaired muscle strength as
potential confounders.20 Fatigue and
physical health warrant further investigation
including what comes first,
fatigue or physical health limitations.
Our findings support the need to
assess for ongoing physical symptoms
(ie, dyspnea, edema) that may increase
susceptibility to increased fatigue. At
the current time, the best method of
assessing for fatigue may be the most
direct and simple, ie, asking patients
about the presence of the symptom
and helping patients to identify fatigue
by specific questioning directed at
uncovering fatigue in the context of
daily activities. Patients who report
a chronic physical symptom pattern
should be screened for concomitant
fatigue that may merit intervention.
Finally, the need to consider interventions
that focus on physical symptoms
as a first step to managing fatigue in
HF patients is vital
