Description: |
Background: Sagittal abdominal diameter (SAD), a measure of visceral adiposity, has been linked to major adverse cardiovascular events (MACE). However, the relationship between SAD and abdominal aortic calcification (AAC), a marker of subclinical vascular disease, and whether they independently and jointly predict MACE remains unclear. Objective: To investigate whether weight-normalized SAD and AAC scored using a validated machine learning algorithm (ML-AAC24) are independently and jointly associated with incident MACE. Methods: SAD and ML-AAC24 were measured from dual-energy X-ray absorptiometry (DXA) posteroanterior and lateral spine images, respectively, from the Manitoba Bone Density registry. Results: Among 8806 individuals (mean age 75.1 ± 6.6 years, 93.9% women), 11.3% experienced MACE during a mean follow-up of 3.8 years. SAD/weight and ML-AAC24 were positively correlated (Spearman r = 0.11, P < 0.001). Individuals with moderate and high ML-AAC24 had 1.1% and 3.0% higher mean SAD/weight, respectively, than those with low ML-AAC24. Both ML-AAC24 and SAD/weight were independently associated with higher risk of MACE. Adjusted hazard ratios [HRs] for MACE were 1.45, 95%CI 1.24-1.71 and 1.99, 95%CI 1.67-2.35 for moderate and high ML-AAC24, respectively, vs. low. The HR for the highest vs. lowest tertile of SAD/weight was 1.37, 95%CI 1.16-1.61. Individuals who had both high ML-AAC24 and were in the highest SAD/weight tertile had the highest MACE risk (HR 2.63, 95% CI 2.02-3.44). Conclusion: Higher baseline SAD/weight was associated with higher ML-AAC24 scores. Both measures independently and jointly associated with MACE. Their combined use may potentially help identify individuals at high risk for cardiovascular disease during routine bone density testing. |
