Key result
Exercise capacity correlated with self-reported physical functioning and general health, though many patients overestimated their physical capabilities.

Does self-reported quality of life correlate with measured exercise capacity in adolescents and adults with congenital heart disease?
Objective exercise capacity correlates with self-reported physical functioning and general health in congenital heart disease patients, but many patients overestimate their physical capabilities, highlighting the need for combined assessment.

Supports combined objective-subjective assessment in congenital heart disease; leaves open whether routine cardiopulmonary exercise testing improves outcomes.
OBJECTIVES: To compare self reported quality of life with measured exercise capacity in patients with congenital heart disease. DESIGN: Prospective cross sectional clinical study. SETTING: Tertiary referral centre for congenital cardiology. PATIENTS AND METHODS: 149 patients (60 female, 14-60 years old) with various congenital heart defects completed a health related quality of life questionnaire (medical outcomes study 36 item short form). Then they performed a cardiopulmonary exercise test on a bicycle in a sitting position. RESULTS: Peak oxygen uptake correlated significantly with the physical functioning (r = 0.521, p < 0.0005) and general health scales (r = 0.313, p < 0.0005) but not with role-physical, bodily pain, vitality, social functioning, role-emotional, mental health, and health transition scales. Closer examination of the data showed that despite an overall good correlation a substantial number of patients overestimated their physical capabilities. CONCLUSIONS: Exercise tests and quality of life instruments should be used together to get an appropriate overview of the health status of patients with congenital heart disease.

Alfred Hager (2005) conducted a cross-sectional in Congenital heart disease (n=149). Self-reported quality of life (SF-36) was evaluated on Correlation between peak oxygen uptake and the scales of the SF-36 health related quality of life instrument (r = 0.521, p=<0.0005). Exercise capacity correlated with self-reported physical functioning and general health, though many patients overestimated their physical capabilities.
