Self-estimated physical functioning poorly predicts actual exercise capacity in adolescents and adults with congenital heart disease

Gratz, Alexander, Hess, John, Hager, Alfred·2009·European Heart Journal

Abstract

AIMS: The aim of this study is to compare self-reported health-related quality-of-life (HRQoL) with the objective of exercise performance in patients with congenital heart disease (CHD) according to diagnosis. METHODS AND RESULTS: 564 patients (255 females, 14-73 years) with various CHD (62 shunt, 66 left heart obstruction, 33 PS/PR, 47 Ebstein, 96 Fallot, 98 TGA after atrial switch, 38 other TGA, 31 Fontan, 32 palliated/native cyanotic, 61 others) and a group of 53 healthy controls (18 females, 14-57 years) completed a QoL questionnaire (SF-36) and performed a symptom-limited cardiopulmonary exercise test. Despite several limitations at exercise (P = 1.30 x 10(-33)), patients only reported reductions in HRQoL concerning physical functioning (P = 4.41 x 10(-15)) and general health (P = 6.17 x 10(-5)) and not psychosocial aspects. This could be confirmed in all diagnostic subgroups. Correlation to peak oxygen uptake was found in physical functioning (r = 0.435, P = 1.72 x 10(-27)) and general health (r = 0.275, P = 3.79 x 10(-11)). However, there was severe overestimation of physical functioning in most patients when compared with actual exercise test results. CONCLUSION: Patients with CHD rate their HRQoL impaired only in physical functioning and general health and not in any psychosocial aspect. Self-estimated physical functioning poorly predicts actual exercise capacity.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
