The aim of this study was to assess whether a specific cardiovascular disease was related to an increased antibody level against a periodontal pathogen.
A strong association between cardiovascular disease and periodontitis was shown, however, the causal relationship was not proven. Increased inflammatory reaction of patients with periodontitis was a possible factor, which connected periodontal infection and vascular diseases.
We assessed medical history, blood data, and periodontal conditions in patients with cardiovascular diseases. Serum IgG antibody titers against major periodontal pathogens and existence of salivary periodontal bacteria were analyzed.
In total, 348 subjects were enrolled in this study. The patients who exhibited 10,000 counts/mL or more of salivary Porphyromonas gingivalis were divided into two groups according to the antibody level of the pathogen. Patients with a high antibody level against Porphyromonas gingivalis exhibited a high rate of heart failure compared to the low antibody group. Mean probing pocket depth and clinical attachment level significantly increased in the high antibody group. We found that the high anti-Porphyromonas gingivalis antibody group also experienced enhanced antibody levels against other periodontal bacteria.
An increased heart failure prevalence was found in patients with a high antibody level against a major periodontal pathogen, Porphyromonas gingivalis.
