The influence of catalaza gene polymorphism on the development of cardiovascular pathology in chronic obstructive pulmonary disease

Distribution analysis of alleles and genotypes of polymorphic markers C-262T catalaza gene in 90 patients with chronic obstructive pulmonary disease (COPD) in connection with presence and character of attendant cardiovascular pathology was made. Detection of polymorphic gene locus was made by polymerase chain reaction. Significant differences in genotypes frequency in patients with COPD and ischemic heart disease (IHD) and without it were discovered. Sstatistically significant increase of genotype CC frequency (relation of possibilities 5,13 p = 0,01) in COPD patients with IHD showed the increased risk of such pathology in CC genotype carriers. Among COPD patients with genotype CC higher indicators of malonate dialdehyde and lower catalaza level in blood serum were detected.
