The aim of this study was to investigate biopsy samples of coronary and internal mammary arteries for the presence of putative pathogenic bacteria (<jats:italic>Porphyromonas gingivalis<\/jats:italic>, <jats:italic>Actinobacillus actinomycetemcomitans<\/jats:italic>, <jats:italic>Prevotella intermedia<\/jats:italic>, and <jats:italic>Tannerella forsythensis<\/jats:italic>), <jats:italic>Chlamydia pneumoniae<\/jats:italic>, and human cytomegalovirus (CMV).<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> Patients with a diagnosis of coronary artery disease were included in the study. Fifteen coronary arteries with atherosclerosis and 15 internal mammary arteries without clinically assessable atherosclerotic degeneration were investigated. Both groups of specimens were obtained during coronary artery bypass grafting surgery. In all cases, the coronary and mammary artery specimens were taken from the same patient. The detection of periodontal pathogens, <jats:italic>C. pneumoniae<\/jats:italic>, and CMV was done by polymerase chain reaction analysis.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> Bacterial DNA was found in nine of 15 (60%) coronary artery biopsy samples: <jats:italic>P. gingivalis<\/jats:italic> in eight (53.33%), <jats:italic>A. actinomycetemcomitans<\/jats:italic> in four (26.67%), <jats:italic>P. intermedia<\/jats:italic> in five (33.33%), and <jats:italic>T. forsythensis<\/jats:italic> in two (13.33%) samples; CMV was detected in 10 (66.67%) samples, and <jats:italic>C. pneumoniae<\/jats:italic> was detected in five (33.33%) samples. Some of the samples contained more than one type of bacteria.
