The total body BMC and BMD was examined using dual energy X-ray absorptiometry (DXA) in 73 adults with complex CHD (mean age 35.8 ± 14.3, women n = 22) and 73 age and sex matched controls.
The adults with complex CHD had lower total body BMC (2.6 ± 0.5 kg vs. 2.9 ± 0.5 kg, p < 0.001) and BMD (1.18 ± 0.12 g/cmvs. 1.26 ± 0.11 g/cm, p < 0.001) compared to controls. BMD was lower for patients with single ventricle physiology and for the other complex diagnoses, and it persisted after correction for most common risk factors for osteoporosis.
Adults with complex CHD have reduced total body BMC and BMD compared to healthy controls. These results are a sign of frailty that conforms with other previously reported signs of premature ageing. The risk of osteoporosis is low in our relatively young population, but it is assumed to increase with ageing. We recommend that clinicians pay close attention to risk factors for osteoporosis, and are generous in administering DXA-measurements in order to prevent future fractures among adults with complex CHD.
