Background: Coronary atherosclerosis and periodontal disease, due to their prevalence, are a serious epidemiological problem. Pathophysiological evidence points to their possible common inflammatory etiopathological background. The aim of the study was to analyze the relationship between the presence and severity of periodontitis, systemic inflammation and selected parameters of myocardial injury and heart function in patients with acute myocardial infarction. Methods: The study group consisted

The patients underwent a coronary angiographic examination and echocardiography. The following laboratory parameters were determined: blood morphology, hsCRP, ESR, fibrinogen, troponin I, CK-MB, BNP, lipidogram, glucose, creatinine, GFR, TSH, HbA1c. Dental assessment of the patients was performed and the following indicators were included: the number of teeth preserved, approximal plaque index (API), bleeding on probing (BoP), pocket depth (PD), the number of bleeding periodontal pockets ≥ 4 mm in depth (NoPD≥4 mm), the percentage of bleeding periodontal pockets ≥ 4 mm in depth (%PD≥4 mm), clinical attachment loss (CAL). The control consisted of 40 patients 52 (± 8.43)- year-old without a history of coronary heart disease. These patients were subjected to a periodontal examination using the above parameters and classification methods. Results: The BI (bleeding index) significantly correlated with fibrynogen. All indices regarding the pocket depth (PD, NoPD≥4mm,% PD4≥mm) correlated significantly with the number of leukocytes. PD and NoPD≥4mm were also associated significantly with the level of hsCRP. The BI is correlated closely with the levels of BNP. The multifactorial analysis showed that significant predictors of myocardial infarction are API and BI. The analysis showed that API and BI are important predictors of troponin levels. Linear regression analysis showed that only CAL is a significant predictor of BNP.Conclusions: Patients with acute myocardial infarction have worse periodontal status compared to people without coronary heart disease. Greater severity of periodontitis, plaque accumulation and bleeding on probing are associated with acute myocardial infarction. Periodontitis is a risk factor for myocardial infarction and also affects the degree of post-infarction left ventricular damage, which means that there is an inflammatory link between these two diseases.
