Bottom Line: Elements are not equally distributed between the inner (intima) and the outer (media + adventitia) layer of the arterial wall.Increased concentration of calcium found in the inner part of the atherosclerotic arterial wall and in the plaque, as compared to the control arterial wall samples, demonstrates the unquestionable role of this element in the calcification of the wall observed in AO.Applied chemometric methods were useful for demonstrating the differences in the element's concentration in blood serum and the arterial wall samples between AO and the control group.

ABSTRACT
The study was aimed to evaluate the influence of the vascular disease, atherosclerotic obliterans (AO), on the location and concentration of elements in the arterial wall and serum. Use of a modern method for studying element's concentration and distribution in samples of clinical material, i.e. laser ablation inductively coupled plasma mass spectrometry, is presented. Elements are not equally distributed between the inner (intima) and the outer (media + adventitia) layer of the arterial wall. Among the studied elements, calcium was found to have an unquestionable role in the calcification of the wall. Increased concentration of calcium found in the inner part of the atherosclerotic arterial wall and in the plaque, as compared to the control arterial wall samples, demonstrates the unquestionable role of this element in the calcification of the wall observed in AO. Applied chemometric methods were useful for demonstrating the differences in the element's concentration in blood serum and the arterial wall samples between AO and the control group.

Fig8: Biplot of elements in P1/P2 dimension constructed for arterial wall data: 1 the AO group, 2 group of healthy people

Mentions: PCA analysis constructed for cases (Fig. 8) identifies two groups, likewise for blood serum samples, which in the majority contain either AO patients or healthy patients. Also, the arrangement of the points is similar compared to blood serum samples. In the case of AO patients (marked as 1), there exist more detached points than in the group of healthy people (marked as 2). Additionally, also two PCs are sufficient (above 72%) for the structure variability explanation. The first PC explained 50.62%, while the second one explained 21.77% of the data variation.Fig. 8
