Existential Well-Being and Suffering in the Context of Cardiac Rehabilitation: A Qualitative Interview Study

This study explores how individuals with ischemic heart disease (IHD) experience well-being and suffering in the early post-discharge period and how these experiences influence their perspectives on cardiac rehabilitation (CR).

A phenomenological-hermeneutic approach was applied. Semi-structured interviews explored participants' lived experiences. The COREQ guideline was followed.

The study is registered in the Internal Directory of Research Projects in the Central Denmark Region (reg. no. 1-16-02-232-19). It adheres to ethical principles for qualitative research, and all participants gave verbal and written informed consent.

We conducted semi-structured interviews with 17 patients recently discharged following hospitalisation for IHD. Interviews were analysed using a five-step meaning condensation process, guided by existential theory on dwelling-mobility.

The overarching theme 'The ambiguity of being mortal and living well' captures the paradox of existential 'homelessness' and possibilities for well-being. Three themes emerged: (1) Existential concerns and considering the severity of the disease-facing uncertainty and struggling to trust in the body; (2) Confidence in returning to a normal everyday life-regaining control through social support and familiar activities; (3) Existential possibilities and appreciation of life-a renewed outlook marked by gratitude and motivation for meaningful change. CR is perceived as a source of reassurance and support, but must feel personally relevant.

Patients' existential experiences shortly after discharge influence their engagement with CR. A person-centred conversation about CR that integrates existential concerns can support well-being, foster confidence and enhance CR participation.
