Background: Depression is a common cause of decreased well-being after open heart surgery (OHS) and a risk factor for new cardiac events. Little is known about the long-term prevalence of depressive symptoms after OHS or their effect on well-being. The aim of this study was to explore the presence of depressed mood in patients during the recovery phase after open heart surgery as well as depressed mood and well-being 3 years later.

Method: Eighty consecutively included patients completed a questionnaire about depressed mood at 5 weeks, 5 months and 3 years after OHS. A telephone interview took place after receipt of the third questionnaire to explore their well-being. Quantitative and qualitative data were analysed separately and thereafter together.

Result: Depressed mood occurred in 52% of the patients during recovery or 3 years after OHS. The qualitative content analysis produced the theme of transition, which was based on three categories.

Conclusion: Depressed mood was reported by the majority of patients during recovery after OHS and had a long-term effect on their well-being. OHS constituted a transition for all patients, but those with depressed mood had difficulty finishing the transition process and reorientating life.
