Abstract
Objectives: Higher complexity of congenital heart defects (CHD) is found to be associated with poorer physical functioning and quality of life (QOL). Within complexity categories, there may be a large variation in outcomes as well, according to the type of CHD. However, prior research is hampered by limited sample sizes. Therefore, we sought to compare the physical functioning and QOL in different CHD from a large international sample.
Methods: In a cross-sectional study, we enrolled 4,028 adult CHD patients from 15 countries. Diagnostic groups with at least 50 patients were included in these analyses, yielding a sample of 3,589 patients (median age=32y; 53% women). Physical functioning was measured using the Physical Component Summary (PCS) of the SF-12 (range 0-100). A linear analog scale was used to measure QOL, ranging from 0 (worst QOL) to 100 (best QOL). Multivariable general linear mixed models were applied to assess the relationship between the type of CHD and physical functioning and QOL, adjusted for New York Heart Association (NYHA) class and other patient characteristics, and with country as random effect.
Results: Patients with coarctation of the aorta reported the highest score on PCS (83.6±17.2) and patients with isolated aortic valve disease had the highest QOL (82.0±13.8) (Fig 1). Patients with cyanotic heart disease or Eisenmenger syndrome showed the lowest scores both on PCS (53.5±21.8) and QOL (67.1±21.8). When taking the CHD with the highest score as reference, the PCS was significantly lower in patients with repaired ductus arteriosus/ASD/VSD, transposition of the great arteries, pulmonary atresia, Marfan, and cyanotic heart disease/Eisenmenger syndrome. For QOL, no differences were found for the types of CHD, when adjusted for other patient characteristics.
Conclusions: Some types of CHD predict worse physical functioning, above and beyond NYHA class and other patient characteristics. CHD type was not found to be an independent predictor for QOL.
