Abstract

ObjectiveTo investigate if oral health parameters were impaired in patients with myocardial infarction (MI) and if there was an association with serum antibody levels against the periodontal pathogens Porphyromonas gingivalis (Pg) and Aggregatibacter actinomycetemcomitans (Aa).MethodsA case–control study consisting of 100 patients with MI and 100 age- and sex-matched controls from the same geographic area was investigated regarding oral health.ResultsThe MI group had significantly more periodontal bone loss (PBL), number of deepened pockets (NDP), and bleeding on probing (BOP), and lower number of teeth (NT) than the controls. After adjustment for known cardiovascular risk factors NT, BOP, and NDP still remained significantly related to MI (p = 0.014, p = 0.02, and p = 0.0069, respectively). IgG antibody levels against Pg were higher in subjects with MI (p = 0.043), as well as in those with > 4 deepened pockets (p = 0.05), BOP > 20% (p = 0.001) and PBL (p = 0.0003). However, indicating a causal pathway, the relationship between MI and Pg IgG disappeared when the oral parameters were included in the logistic regression model (p = 0.69). No correlation was seen between MI and Aa in the present study.ConclusionPatients with MI had an impaired oral health compared to controls. Furthermore, IgG levels against Pg were related to both MI and oral health, suggesting this pathogen as a possible link between oral health and CVD.
