Background: The aim of the study was to evaluate the impact of clinical periodontal parameters and the presence of periodontal pathogens in patients with acute myocardial infarction (AMI).
Methods: A total of 104 subjects (54 patients with AMI and 50 healthy controls) were included. Subgingival plaque samples were analyzed for periodontal pathogens Aggregatibacter actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg), Tannerella forsythia (Tf) and Prevotella intermedia (Pi) using dot blot hybridization.
Results: AMI patients had a significantly higher frequency of probing depths (PD) of ≥4 mm than controls (39.2% vs. 14.9%, P <0.0001). p =” 0.0005).” p =” 0.0005)” p =” 0.0018)” style=”font-weight: bold;”>Conclusion: The results of our study confirm an association between periodontitis and AMI, in which periodontal destruction was correlated with the presence of periodontal pathogens. In particular, Pg might be considered as potential risk indicator for AMI.
