[Association between chronic periodontitis and acute myocardial infarction]

ABSTRACT

Chronic periodontitis has been associated with cardiovascular diseases. The hypothesis that oral espically periodontal, infections systemic implications, is now gaining evidence. In this Case- control study, cases were 45-60 years old patients who had been hospitalized in one of cardiologic care units or emergency wards of Isfahan city such Chamran and Khorshid Shahr hospitals, for acute myocardial infarction [AMI]. Control group had no evidence of acute myocardial infarction, all receiving comprehensive periodontal examination. Information such as age, socioeconomic state, smoking and Dm history were obtained from hospital records and direct interview. Dependent variants attachment loss [AL] and lost teeth have been considered as characteristics of periodontal disease. In this research a total of 56 samples participated in our study, based on informed consent. The association between mean attachment level and number of missing teeth with studied groups were analyzed with paired t -test and SPSS 15 software. Research findings showed that AL index mean in patients group [MI patients] and control group [healthy group] was 3.11 +/- 1.05 and 2.46 +/- .85 and lost teeth index mean in patients group and control group was 7.78 +/- 5.12 and 4.67 +/- 3.47 respectively. The statistical test showed that these differences in both indexes with p<0.05 are significant. According to the findings, we can advise if elders in ordinary dentistry examinations show signs of periodontal disease and have some lost teeth may have higher risks for cardiovascular disease
