Gravity of aortic arch calcification as evaluated in adult Greek patients.

Background: The aim of the present study was to evaluate the gravity of aortic arch calcification in adult Greek patients.
Methods: A total of 1027 patients (498 men, 529 women) were included. Aortic arch calcification was assessed by means of posteroanterior chest X-rays. These were studied by two radiologists blinded to the patients' medical records. Calcification was graded as follows: grade 0 (no visible calcification), grade 1 (small spots of calcification or single thin calcification of the aortic knob), grade 2 (one or more areas of thick calcification), grade 3 (circular calcification of the aortic knob). All patients were clinically and electrocardiographically examined for coronary artery disease. The other parameters included in the analysis were age, sex, smoking, body-mass index, hypertension, dyslipidemia, diabetes mellitus and history of stroke.
Results: Calcification gravity was grade 0 in 421 patients (41%), grade 1 in 308 patients (30%), grade 2 in 216 patients (21%) and grade 3 in 82 patients (8%). In simple regression analysis the gravity of aortic arch calcification was positively correlated with age (p=0.01), diabetes mellitus (p=0.014), hypertension (p=0.022), dyslipidemia (p=0.038) and coronary artery disease (p=0.041). In multiple regression analysis it was associated with age (p=0.019), diabetes mellitus (p=0.02) and hypertension (p=0.03).
Conclusions: Gravity of aortic arch calcification in adult Greek patients may easily be assessed on routine chest X-rays and is positively correlated with coronary artery disease, as well as important cardiovascular risk factors (age, diabetes mellitus, hypertension and dyslipidemia).
