Echocardiographic assessment of epicardial fat tissue thickness in patients with severe periodontitis
MetadataShow full item record
Objectives: This study aims to assess the thickness of epicardial fat tissue (EFT), a sign of cardiovascular risk, using echocardiography in patients with severe periodontitis. Methods: Thirty-three patients with stage III or IV periodontitis and 33 healthy participants were enrolled into the study. Epicardial fat tissue thickness was measured perpendicularly via echocardiography of the free wall of the right ventricular at end-diastole in three cardiac cycles. Body mass index (BMI) was calculated by dividing weight in kilograms by the height in meters squared. EFT to BMI ratio (EFT/BMI) was measured by dividing EFT by the BMI. Results: There was no significant difference between study patients and the control group as regards to the frequency of diabetes, hypertension, smoking, and hyperlipidemia. The EFT and EFT/ BMI ratio were significantly different in the control and periodontitis groups (0.510.17 vs. 0.77 +/- 0.16, respectively; p <0.001) (0.021 +/- 0.008 vs. 0.030 +/- 0.006, respectively; p<0.001). Pearson's correlation coefficient demonstrated a significant relationship between EFT and the clinical parameters of periodontitis (p<0.001) Conclusions: EFT thickness measured by echocardiography appears to be associated with severe periodontitis and may thus be an indirect sign of cardiovascular disease in periodontitis patients.
