Sense of Coherence as a Mediator Between Functional Status and Health-Related Quality of Life in Patients With Heart Failure.

In patients with HF, poor functional status often reduces HRQOL significantly. SOC mediates the relationship between functional status and HRQOL more significantly in those in NYHA Class II than those in Class III. Nursing staff should work to increase patients' SOC by strengthening their coping capacity and improving their functional status to improve their HRQOL.
