Abstract

OBJECTIVE To evaluate cardiovascular disease (CVD) and total mortality associated with thoracoabdominal calcifications.

RESEARCH DESIGN AND METHODS Thoracoabdominal calcifications of native radiograms were evaluated in 833 subjects with type 2 diabetes and 1,292 subjects without diabetes, aged 45–64 years, without prior evidence of CVD. The type 2 diabetic and nondiabetic study cohorts were followed up for 18 years.

RESULTS After adjustment for conventional risk factors, marked thoracoabdominal calcifications predicted CVD/total mortality with hazard ratio (HR) (95% CI) of 1.5 (0.8–3.0)/1.8 (1.1–2.9) in type 2 diabetic men, 3.0 (1.6–5.7)/3.1 (1.9–5.0) in type 2 diabetic women, 5.0 (2.2–12)/4.0 (2.2–7.4) in nondiabetic men, and 7.8 (1.8–34)/3.0 (1.3–7.0) in nondiabetic women and in the presence of C-reactive protein below/over 3 mg/l with HR of 2.4 (1.3–4.4)/3.0 (1.4–6.1) in type 2 diabetic subjects and 4.0 (1.5–10.8)/6.6 (2.7–16.0) in nondiabetic subjects.

CONCLUSIONS Thoracoabdominal calcifications in native radiograms are significant predictors of CVD and total mortality, especially in type 2 diabetic and nondiabetic women with elevated high-sensitivity C-reactive protein level.
