Health-Related Physical Fitness and Quality of Life in Children and Adolescents With Isolated Left-to-Right Shunt

Health and Well-Being in Older Adults With a Surgically Closed or an Unrepaired Ventricular Septal Defect

Background Older adults with a congenital ventricular septal defect (VSD) recently exhibited reduced heart rate variability and exercise capacity. It is unknown whether these findings affect health-related quality of life. Methods and Results Adults with VSDs and healthy controls, all concurrently included as part of another clinical study, completed the Danish National Health Survey questionnaire. Questionnaire data distributed to the general population were included and matched 10:1 with patients. Thirty patients with surgically closed VSDs (mean±SD age, 51±8 years), 300 adults from the general population (mean±SD age, 50±8 years), and 30 controls (mean±SD age, 51±9 years), as well as 30 patients with unrepaired VSDs (mean±SD age, 55±11 years), 300 adults from the general population (mean±SD age, 55±12 years), and 30 controls (mean±SD age, 55±10 years) completed the questionnaire. Educational level, social relations, and physical activity were comparable between groups. A larger proportion of patients with unrepaired VSDs compared with the general population experienced migraine (47% versus 24%; P=0.04), whereas more patients with surgically closed VSDs were affected by depression (13% versus 4%; P=0.02). For health-related quality of life, patients with surgically closed VSDs reported lower physical functioning (P<0.01), physical component summary (P<0.01), general health perception (P<0.01), and higher stress score (P=0.03) compared with the general population and healthy controls. Patients with unrepaired VSDs reported lower scores on physical functioning (P=0.03), bodily pain (P<0.01), and mental health (P=0.02), and a higher stress score (P=0.03), than controls. Conclusions Older patients with VSDs report lower self-perceived physical functioning, lower general health, and higher stress levels, all in line with previous findings, like lower exercise capacity and dysfunctional cognitive abilities, in adults with VSDs. Incessant follow-up is paramount, as neither successfully closed nor hemodynamically insignificant VSD is equivalent with untroubled healthy aging.

Impaired grip strength in children with congenital heart disease

OBJECTIVES

Grip strength is known to be reduced in adults with congenital heart disease (CHD). This study compared grip strength in paediatric patients with CHD with healthy controls and determined a possible association between grip strength and health-related physical fitness (HRPF).

METHODS

Grip strength and HRPF were assessed in 569 children (12.4 years, 95% CI 12.16 to 12.72; 238 girls) with various CHD and compared with 2551 healthy controls (11.4 years, 95% CI 11.3 to 11.5; 1424 girls). Grip strength was determined as the maximum value of three repetitions with each hand. HRPF was tested by five motor tasks (FITNESSGRAM) and converted into an SD score (z-score).

RESULTS

After adjusting for age, sex and weight, children with CHD showed significantly lower grip strength compared with healthy controls (CHD: 20.8 kg, 95% CI 20.4 to 21.2; controls: 24.5 kg, 95% CI 24.3 to 24.8). CHD subgroup analysis also revealed significantly lower grip strength than the controls, with the lowest values in patients with total cavopulmonary connection (19.1, 95% CI 18.0 to 20.2). Children with complex CHD showed the lowest values with 19.8 kg (95% CI 19.2 to 20.4), those with moderate 20.7 kg (95% CI 19.9 to 21.4) and those with simple 22.5 kg (95% CI 21.6 to 23.3), respectively. HRPF was also lower (z-score: -0.46, 95% CI -0.49 to -0.35) compared with healthy controls and poorly associated with grip strength (r=0.21).

CONCLUSIONS

Grip strength is already reduced in children with CHD and poorly associated with HRPF. This suggests that grip strength and HRPF are different domains and have to be assessed separately.

Move more - be happier? physical activity and health-related quality of life in children with congenital heart disease

OBJECTIVE

This cross-sectional study aimed to determine whether there is an association between objectively assessed physical activity (PA) and health-related quality of life (HRQoL) in children with CHD.

PATIENTS AND METHODS

From September 2017 to January 2021, 343 children with CHD (12.1 ± 3.3 years, 135 girls) provided valid PA data after a 7-day objective PA assessment. PA was evaluated as average daily steps and moderate-to-vigorous physical activity (MVPA) minutes assessed via wearable bracelet Garmin vivofit Jr. These children also completed the KINDL - a 24 Likert-scaled item questionnaires assessing HRQoL in the six dimensions physical well-being, emotional well-being, self-esteem, family, friends and everyday functioning.

RESULTS

Daily Steps (r = 0.166, P = .003) and daily MVPA minutes (r = 0.134, P = .017,) were both correlated to total KINDL score. Furthermore, both steps and MVPA were associated with the subscales physical well-being (steps: r = 0.165 p=.003; MVPA: r = 0.129, P = .022), friends (steps: r = 0.210, P < .001, MVPA: r = 0.179, P = .001), steps, and to everyday functioning (r = 0.142, P = .012). Logistic regression showed each MVPA minute increase conferred to a 1% increase in reporting better HRQoL (OR: 1.009 [95% CI: 1.002 - 1.017], P = .019).

CONCLUSIONS

PA was positively associated with HRQoL in children with CHD. Patients who move more are more likely to report better HRQoL. While the magnitude of this association needs to be further understood, continuous encouragement towards more PA seems to be crucial in a holistic approach to medical aftercare in children with CHD.
