Relationship quality, dyadic coping, and depression in couples with left ventricular assist device implantation

AIMS

Living with a left ventricular assist device (LVAD) can be associated with many burdens and worries for patients. They are often dependent on the support of their spouses. This can also be a burden on the spouses and the relationship. However, the relationships quality of LVAD couples has so far scarcely been investigated. Couple's mutual coping with stress (dyadic coping, DC), as well as depression are important factors influencing relationship quality. To examine patients' with an LVAD and their partners' ability to cope with stress and levels of depression, and the impact these have on relationship quality.

METHODS AND RESULTS

The study investigates relationship satisfaction in couples after LVAD implantation as well as influencing factors such as DC or depression. Differences in relationship quality, DC, and depression between patients and spouses are examined using validated questionnaires. N = 39 heterosexual couples with male patients participated. Relationship quality of patients was higher than that of their spouses. The actor-partner-interdependence model provided for spouses actor effects on relationship satisfaction of their own DC, partner DC, and depression. For patients, actor effects of partner DC and depression as well as a partner effect of depression were found. In addition, DC of patients was estimated by both partners to be lower than DC of spouses.

CONCLUSION

The results indicate a high rate of depression among LVAD patients and spouses. This study contributes to the knowledge about the mental state of LVAD couples and demonstrates that the spouses should be considered during treatment.

Depression, anxiety, fear of progression, and emotional arousal in couples after left ventricular assist device implantation

AIMS

Left ventricular assist device (LVAD) is a common treatment option for patients with heart failure waiting for a donor heart. Living with an LVAD is associated with many burdens and worries. Patients often depend on the support of their relatives, usually their spouses. This can also put a strain on the spouses and be associated with psychological stress for both. In couples, communication proves to be an important form of emotional support. Besides verbal aspects of communication, the extent of emotional arousal (f₀ ) that is vocally encoded plays an essential role as a non-verbal aspect of communication. This study aims to investigate the psychological impact of LVAD on couples in investigating to what extent depression, anxiety, and fear of progression (FoP) differ between patients and partners, the intrapersonal and interpersonal associations of anxiety, depression, and FoP, and differences in emotional arousal.

METHODS AND RESULTS

In this cross-sectional study, male LVAD patients and their female partners (N = 21 couples) responded to self-report questionnaires on depression, anxiety, and FoP. Emotional arousal (f₀ ) was evaluated during social support interactions between both spouses. Female partners experienced more anxiety than male patients (P = 0.016). No differences occurred in depression (P = 0.967) and FoP (P = 0.084). Regarding intrapersonal associations, for patients, correlations appeared between anxiety and depression (r = 0.859, P = 0.000), anxiety and FoP (r = 0.730, P = 0.000), and depression and FoP (r = 0.608, P = 0.004). For caregivers, correlations appeared between anxiety and depression (r = 0.906, P = 0.000), anxiety and FoP (r = 0.665, P = 0.001), and depression and FoP (r = 0.734, P = 0.000). Regarding interpersonal associations, correlations were found between patient's anxiety and caregiver's anxiety (r = 0.461, P = 0.041), caregiver's depression (r = 0.510, P = 0.018), and caregiver's FoP (r = 0.524, P = 0.015). Non-significant correlations were found for caregiver's anxiety and patient's FoP (r = 0.404, P = 0.078) and patient's depression (r = 0.286, P = 0.236). Patient's depression was associated with caregiver's FoP (r = 0.526, P = 0.017), but not with caregiver's depression (r = 0.337, P = 0.146). No significant correlations were found between caregiver's depression and patient's FoP (r = 0.386, P = 0.084) and patient's depression (r = 0.337, P = 0.146). Patient's and caregiver's FoP showed significant associations (r = 0.482, P = 0.027). Patient's and partner's f₀ were interrelated. Patient's f₀ was positively related with his own and his partner's psychological distress. Partner's f₀ showed associations to her own depression and FoP.

CONCLUSIONS

Findings indicate that women of LVAD patients are burdened similarly or even to a greater extent than men themselves. Women's psychological distress has an impact on patients' psychological distress and vice versa. Early interventions for both patient and partner represent a necessary intervention target.
