Perceived consequences, changeability and personal control of coronary heart disease are associated with health-related quality of life.

Aims And Objectives: To explore changes in illness perception and health-related quality of life in patients with coronary heart disease following percutaneous coronary intervention from the time when patients were discharged from hospital and five months later and to investigate association between illness perception and physical and mental health-related quality of life at five-month follow-up.

Background: Illness perception is known to influence patients' motivation to engage in preventive behaviour.

Design: Prospective and comparative with two measurement points: at discharge from hospital (time 1) and five months later (time 2).
