| dc.description.abstract | DNA and chromosomal damage in peripheral blood leukocytes of patients with coronary artery disease (CAD) were investigated by using the single cell gel electrophoresis assay /comet and cytokinesis- block micronucleus (CBMN) assays, respectively. The case-control study comprised patients with CAD (n = 46; average age 53.0 ± 1.27 y) undergoing treatment at local hospitals, and healthy age-and sex-matched controls (n = 19; average age 54.21 ± 0.91 y) from the general population. The results of the comet assay revealed that the mean values of DNA damage were significantly (p < 0.001) higher in CAD patients than in controls (Tail DNA% 11.55 ± 0.38 vs. 5.31 ± 0.44; Tail moment 6.17 ± 0.31 vs. 2.93 ± 0.21 AU; Olive tail moment 3.52 ± 0.23 vs. 1.25 ± 0.11 AU). The mean values of chromosomal damage were also significantly higher (p < 0.001) in CAD patients than in controls (Binucleated cells with MN-28.15 ± 1.18 vs. 18.16 ± 2.59; micronuclei 29.52 ± 1.21 vs. 18.68 ± 2.64, respectively) while nuclear division index (1.48 ± 0.01 vs. 1.63 ± 0.01) was significantly higher (p < 0.001) in controls. The results of the present study indicate that coronary artery disease patients had increased levels of both, unrepaired (DNA) and repaired (chromosomal) genetic damage which may be a pathological consequence of the disease and/or the drug-treatment. This accumulation of DNA/chromosomal damage is of concern as it can lead to the development of cancer with increased chances of morbidity and mortality in the CAD patients. | en |
