BACKGROUND: The purpose of this cross-sectional study was to assess the periodontal condition of patients with coronary artery disease (CAD) in order to verify the association between CAD and certain periodontal parameters. METHODS: Eighty patients (48 males and 32 females) were recruited from the Cleveland University Hospitals, Division of Cardiology (aged 23 to 83, median age 54 years). Upon cardiac catheterization, 50 were diagnosed with severe CAD (experimental group) and 30 with no angiographic evidence of CAD (control group). Patients with CAD were divided into 3 subgroups according to the clinical diagnosis of acute infarction (Al) (n = 20), stable angina (SA) (n = 20), and unstable angina (UA) (n = 10). The following dental, medical, and social histories were recorded: number of dental visits/year, frequency of brushing/day and flossing/week, tobacco use, presence/absence of hypertension, diabetes, total cholesterol level, and the highest level of education completed. The following periodontal parameters were also assessed for each subject: plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), clinical attachment level (CAL), and number of missing teeth. Logistic regression analysis was used to determine whether there was a significant correlation between these periodontal parameters and CAD. RESULTS: The significant confounding factors for the present study were found to be age and gender. The periodontal condition of the 80 subjects was clinically diagnosed as gingivitis and/or mild periodontitis. Analysis of the data after adjusting for age and gender demonstrated a statistically significant association between BOP and GI and CAD in patients with Al; and facial/lingual CAL in patients with UA. No significant associations were found between PD, interproximal CAL, number of missing teeth, or dental/medical histories and CAD. CONCLUSION: Based on the results of this study, gingival inflammation may be considered a more significant risk factor for CAD than previously reported.
