[Measurement of coronary artery calcification in adults with type 1 diabetes mellitus using dual-source, multi-slice computed tomography]

MAUROVICH-HORVAT Pál

[INTRODUCTION - Coronary artery calcification can be characterized non-invasively and numerically using computed tomography (CT). In adult patients with type 1 diabetes mellitus, coronary atherosclerosis may be present without clinical symptoms. PATIENTS AND METHODS - Asymptomatic adults with type 1 diabetes mellitus (n=46) were investigated. Coronary artery calcification was expressed in Agatston-scores using a dual source CT scanner. RESULTS - Twenty-one patients had a coronary artery calcification score of ≥1 (range 1-2353), while in 25 patients no detectable calcium (score 0) was observed. Patients with vs. without coronary artery calcification had a higher age (51.0±9.9 vs. 42.8±7.8 years; p=0.0045), a longer duration of diabetes (30.6±9.2 vs. 24.2± 8.6 years; p=0.0238), a higher waist circumference (87.9±11.5 vs. 79.7±9.4 cm; p=0.0146), and a higher BMI (26.2±2.9 vs. 23.8±3.1 kg/m2;p=0.0109). Moreover, patients with vs. without detectable coronary artery calcification had higher serum lipid levels (LDL-cholesterol, 3.35±0.32 vs. 3.01±0.68 mmol/l; p=0.0069) and higher serum uric acid levels (228.4±48.7 vs. 195.1±39.4 µmol/l; p=0.0437). Hypertension was more common (p=0.0144) in patients with coronary artery calcification than in patients without it. There was no significant difference between the groups in HbA1c (7.97±0.85 vs. 8.26±1.28%; p=0.7491), however, estimated insulin sensitivity was lower in patients with vs. without detectable coronary artery calcification (7.15±2.09 vs. 9.20±2.03 mg/kg/min; p=0.0017). CONCLUSION - Our results suggest that coronary artery disease in type 1 diabetic patients is associated with higher age, longer duration of diabetes, and cardiovascular risk factors rather than with long-term glucose control.]
