Testing of a health-related quality of life model in patients with heart failure: A cross-sectional, correlational study.
Seongkum Heo, Terry A Lennie, Debra K Moser and 3 others
PMID 35104725WHAT IT FOUND
In 358 adults with heart failure, poorer quality of life was linked to more physical symptoms, more depression, worse function, lower social support, more other health problems, and younger age.
Sodium adherence linked to quality of life through symptoms. No treatment effect was tested.
Key findings
01The tested model fit the data and explained 63.7% of variance.
02Age, depressive symptoms, physical symptoms, and functional status were directly associated with HRQOL.
03Comorbidity, social support, and dietary sodium adherence were associated with HRQOL only through other factors.

What it does not show
The analysis used only baseline data from two earlier studies, so it cannot show that any factor caused poorer quality of life. It was a secondary analysis, and some relevant factors, such as spiritual factors, health perception, cognition, and inflammatory biomarkers, were not included. The mean age was 60.44 years, which is younger than many older adults with heart failure, so results may not apply to very old patients. Of 472 patients enrolled in the parent studies, 11 withdrew or were lost to follow-up and 103 had missing data, so the analysed sample may not represent all enrolled patients. Dietary sodium adherence was measured as 24-hour urine sodium, which may not capture all diet behaviours.

The easy way to misread this
Do not read the 63.7% variance explained as proof that changing these factors will improve quality of life. This was a cross-sectional model of associations, not a treatment study.
