Restenosis after percutaneous coronary intervention (PCI): experiences from the patients' perspective

PCI has been established as an effective treatment for coronary artery disease. Restenosis is a recurrence of a significant narrowing in the treated vessel. Although a part of the investigative and research funding is invested in the prevention and resolving the restenosis problem, little is known about its clinical significance apart from further revascularisation.

The intention of this study was to clarify the patients perspective of what it means to suffer from documented restenosis after PCI.

Patients interviewed had undergone PCI. Data collection and analysis was done simultaneously according to Grounded Theory methodology and continued until new interviews provided no additional information.

"Living with uncertainty" was identified as the core category, and the central focus in the data explains what it means to patients' to suffer from restenosis. The core category was further illuminated in four additional categories labelled "fighting for access to care", "moderating health threats", "trying to understand" and "controlling relatives anxiety".

Patients' perceptions of illness and illness-related events, such as symptoms, diagnosis, treatment and prognosis, are considerably affected by uncertainty. This infiltrates their struggle to acquire the care needed, their endeavour to comprehend and moderate health threats, and caring for their family.
