Self-reported physical activities in patients after the Mustard or Senning operation: Comparison with healthy control subjects

Enablers and barriers for being physically active: experiences from adults with congenital heart disease

BACKGROUND

In general, adults with congenital heart disease have reduced exercise capacity and many do not reach the recommended level of physical activity. A physically active lifestyle is essential to maintain health and to counteract acquired cardiovascular disease, therefore enablers and barriers for being physically active are important to identify.

AIM

To describe what adults with complex congenital heart diseases consider as physical activity, and what they experience as enablers and barriers for being physically active.

METHODS

A qualitative study using semi-structured interviews in which 14 adults with complex congenital heart disease (seven women) participated. The interviews were analysed using qualitative content analysis.

RESULTS

The analysis revealed four categories considered enablers and barriers - encouragement, energy level, approach and environment. The following is exemplified by the category encouragement as an enabler: if one had experienced support and encouragement to be physically active as a child, they were more positive to be physically active as an adult. In contrast, as a barrier, if the child lacked support and encouragement from others, they had never had the opportunity to learn to be physically active.

CONCLUSION

It is important for adults with congenital heart disease to have the opportunity to identify barriers and enablers for being physically active. They need knowledge about their own exercise capacity and need to feel safe that physical activity is not harmful. This knowledge can be used by healthcare professionals to promote, support and eliminate misconceptions about physical activity. Barriers can potentially be transformed into enablers through increased knowledge about attitudes and prerequisites.

Association between N-terminal pro-brain natriuretic peptide and quality of life in adult patients with congenital heart disease

AIMS

Advances in medical treatment have resulted in increased life expectancy in congenital heart disease. Consequently, the focus of management has shifted from reducing mortality to reducing long-term morbidity with the goal of improving quality of life. A predictor of quality of life might be N-terminal pro-brain natriuretic peptide, a well-established marker for heart failure. We aimed to determine the association between N-terminal pro-brain natriuretic peptide and quality of life in patients with congenital heart disease.

METHODS

We collected blood samples from consecutive patients who were initially operated between 1968 and 1980 (47.8% women; mean age 40.2±5.4 years). The 36-item Short-Form Health Survey was completed to assess subjective health status as a measure of quality of life. Analysis was performed for the entire group and for subgroups defined as simple versus complex congenital heart diseases. Median N-terminal pro-brain natriuretic peptide level was 15.2 pmol/L (overall range 1.3-299.3 pmol/L). N-terminal pro-brain natriuretic peptide levels were associated with the subdomain physical functioning (β=-0.074, p=0.031). This association remained significant after adjustment for age and sex (β=-0.071, p=0.038) and after adjustment for age, sex, body mass index, left ventricular function, and renal function (β=-0.069, p=0.048). In complex congenital heart disease, the association between N-terminal pro-brain natriuretic peptide and physical functioning remained significant in multivariable analysis (β=-0.076, p=0.046). No associations were found in the simple congenital heart disease group or on the other health status subdomains.

CONCLUSION

In adults operated for congenital heart disease, N-terminal pro-brain natriuretic peptide is associated with the subdomain physical, primarily in the complex subgroup.
