Aim And Objective: The aim of this study was to investigate the association between periodontal disease and acute myocardial infarction. Materials And Methods: A total number of 120 patients were selected for the study. 60 patients who were examined immediately following an episode of myocardial infarction were selected as test group and 60 patients suffering from chronic coronary heart disease were selected as control group for the study.The study was conducted with the help of medical history, periodontal examination and analysis of enzyme profile of the patient. Results: Results of Multiple Logistic Regression Analysis [MLRA] without adjusting for confounding factors showed that Plaque Index [PI :2: 2], Periodontal Disease Index [PDI :2: 4] and Low Density Lipid [LDL] were associated with Acute Myocardial Infarction [AMI]. Former smokers showed a significantly lower risk for AMI. After adjusting for age, current smoking, diabetes, hypertension, LDL and High Density Lipids [HDL], the results showed that PI ::2: 2 and PDI :2: 4 were not significantly associated with AMI. Conclusion: It could be concluded that PI :2: 2 and PDI :2: 4 showed a significantly positive association with AMI, when the confounding factors were not adjusted. But once the confounding factors were adjusted PI 2 and PDI :2: 4 showed no association. This shows that risk factors such as smoking and hyperlipidemia have a more profound association with AMI than periodontal disease.
