Background: The belief that conditions affecting the mouth could have implications on peripheraltissue and organs has been held from the very earliest medical recordings. The role of the "classic"cardiovascular disease (CVD) risk factors, however, does not explain all clinical and epidemiologicalfeatures of CVD. The hypothesis that oral infections, especially periodontal infections, have potentiallyserious systemic implications is now gaining credence. Based on the clinical impression that periodontaldisease is common among patients with myocardial infarction, this study is taken up to assess theperiodontal health status among these patients and to know the association between periodontal diseaseand acute myocardial infarction. (AMI). Material and methods: The study groups comprised of a total of 102 (50 cases and 52 controls)subjects at Narayana institute of cardiac sciences, Bangalore. The cases with proven clinical and laboratorydiagnoses of a first attack of AMI event and age matched controls without any history of AMI . All thesubjects under went a complete periodontal examination using Community periodontal index, lipid andblood glucose profile tests, weight and height, Blood pressure checkup and a questionnaire on sociodemographic and life style conditions. Statistical analysis: Chi square test and t test were used for significance of any difference inproportions and means respectively. To estimate the association, Logistic regression analysis was used toasses the relation of periodontal disease risk for AMI. Results: Univariate analysis showed statistically significant results between males, aged patients,smoking, hypertensive, diabetics and alcoholics. these risk factors were further forced into the regressionmodel to adjust for their impact on AMI and the significant variables were current smokers, hypertension,and CPI code 4 were (with p value <.05)statistically significant. Conclusions: Severe periodontitis was found to be more common in patients with AMI and supportsthe previously reported association of periodontitis as a risk factor for AMI.
