Background: Coronary heart disease is the leading cause of adult mortality and morbidity throughout the world. Well known risk factors independently or combined are involved in both atherosclerosis and myocardial infarction. Recent data have shown that viral and bacterial infections may also contribute to acute thromboembolic events, hence a case control study was carried out.

Aims: To investigate the possible association between periodontal health and patients with Acute Myocardial Infarction (AMI).

Material and Methods: 50 patients, and 50 control were included in the study. Data on hypertension, diabetes, and smoking status were recorded. Clinical examination of AMI patients was carried out during the hospital stay. Clinical Attachment Loss performed for all subjects.

Results: There were no significant variations between the groups regarding the age, gender and BMI, while more incidence of risk factors in patients. There were significant worsening of grades of periodontitis with increasing age. Higher incidence of periodontitis in patients with AMI were distinguished. Those with unhealthy periodontium shows 11.5 times higher chance to have AMI. Most of the subjects in control group (92%) had healthy periodontium, whilst advanced periodontitis was limited to the patients only (50%). The bulk of the subjects (63%) were either overweight or obese, meanwhile, only 3.3% of the subjects were underweight. No statistically significant relationship of obesity with occurrence of AMI. No significant differences between the groups existed in the relation of BMI and grades of periodontitis.

Conclusion: Overall result of this case control study showed an association between periodontitis and acute myocardial infarction.
