Background and methods: 362 symptomatic subjects of 45 years of age or younger were selected from a large database of around 4100 persons who underwent coronary artery calcium (CAC) scoring by means of a 64-multidetector computed tomography (MDCT). Amongst them, a group with the CAC > 0 Agatston units (n = 65) and a group with no detectable calcium (CAC = 0, n = 297) were compared in terms of risk factors presence. Risk factors considered were gender, body mass index, smoking habits, blood pressure level, blood lipids, presence of diabetes mellitus, family history of cardiovascular disease, and physical activity.

Results: The vast majority of subjects with a positive CAC were males (54, 83.1%) compared to those with a negative CAC (147, 49.5%, p < 0.001, χ2). More frequent results of CAC > 0 were observed in obese subjects (38.5% vs. 24.2%, p < 0.05), among smokers (41.5% vs. 27.6%, p < 0.05). Presence of arterial hypertension coexisted with a more frequent CAC > 0 (76.9% vs. 60.6%, p < 0.05). Also, the frequency of a positive CAC was significantly higher in patients with diabetes mellitus (10.8%), compared to those without diabetes mellitus (4.0%, p < 0.05). Effects of high lipids, family history, and physical activity were not observed. Accumulation of at least 4 risk factors was associated with more frequent positive CAC (26.0 vs. 15.9%, p < 0.05). Multivariate regression analysis showed that only male gender and presence of diabetes mellitus were independent predictors of a positive CAC in younger subjects (F = 5.06, p < 0.001, multiple R = 0.321).

Conclusions: Traditional risk factors, apart from gender and diabetes mellitus, do not seem to allow for distinguishing young persons with a premature coronary atherosclerosis. Therefore, CAC scoring might be considered justified in symptomatic young men with diabetes mellitus/
