Aortic calcification (lateral radiographs)
Contact: Natasja van Schoor
In the Framingham Heart Study, it was shown that middle-aged men and women with calcific disease in the abdominal aorta are more likely to develop coronary heart disease, cardiovascular disease (CVD), and CVD mortality (2).
Measurement instruments in LASA
LASA respondents who participated in the C-examination (1995/1996), were born in 1930 and before (aged 65 years and older as of 1 January, 1996) and were living in the west of the Netherlands (Amsterdam and its surroundings) were invited to the VU University Medical Center for a spinal lateral radiograph. Of the 695 respondents who were invited, 535 respondents (77%) were willing to come to the hospital. Non-responders were older, had more functional limitations and lower self-perceived health, but had a similar gender distribution (1). Valid spinal radiographs were obtained in 527 of these participants. Only respondents with a valid lateral radiograph at LASA-C were invited for a repeated lateral radiograph at LASA-D examination (1998/1999). In total, 338 subjects had a valid repeated spinal radiograph at LASA-D.
In addition to assessment of vertebral deformities and disc degeneration, the degree of aortic atherosclerosis was examined on the lateral radiographs of LASA-C and LASA-D. On each radiograph, the length of the aorta was examined with a ruler, and subsequently scored as: 1: no aortic atherosclerosis; 2: aortic atherosclerosis 1 cm; 3: aortic atherosclerosis 2-5 cm; 4: aortic atherosclerosis 6-10 cm; 5: aortic atherosclerosis >10 cm.

Previous use in LASA
Aortic calcification was used as a mediator in research of Holvik et al. (2014), exploring the relationship between osteocalcin and cardiovascular disease. A higher plasma OC concentration was associated with a reduced risk of CVD in older-old men and with an increased risk of CVD in older-old women. However, this relationship was not mediated by aortic calcification. Buizert et al. (2013) stated that the presence of serum PTH levels within the upper normal range is highly related to CVD. In the case of men, this relationship may be partly mediated by calcifications of the abdominal aorta.
