Abdominal Aortic Calcification (AAC)
High Definition Instant Vertebral Assessment allows you to visualize calcified plaques in the abdominal aorta, which may be a significant indication of heart disease and stroke.1-3 Coronary heart disease (CHD) is the leading cause of death of women in America and most developed countries, with nearly 39 percent of all female deaths in the U.S. occurring from CHD.
Despite advances in treating CHD, a large number of CHD victims die suddenly without prior symptoms. Many coronary heart specialists now believe that available screening and diagnostic methods are insufficient to identify high-risk CHD patients before the first event occurs. 6 As a result, there is an interest in the detection of preclinical or subclinical atherosclerosis.
Exclusive to the Discovery DXA system from Hologic is the ability to visualize abdominal aortic calcification in addition to its use in osteoporosis and vertebral deformity assessment.
The new indication, visualizations of abdominal aortic calcifications (AAC) in a standard bone density test, may help the physician identify the number one cause of morbidity and mortality in older men and women - heart disease and stroke.1-3 AAC is significantly associated with both cardiovascular heart disease and stroke even after adjustment for the traditional risk factors of age, cigarette use, diabetes mellitus, systolic blood pressure, left ventricular hypertrophy, body mass index, cholesterol, and HDL cholesterol 4-7.
