Left ventricular geometry and periodontitis in patients with the metabolic syndrome

Abstract

Objective

The presence of periodontal disease (PD) in subjects affected by the metabolic syndrome (MetS) may affect their risk of developing cardiovascular disease. The aim of this cross-sectional study was to investigate the systemic impact of PD in MetS, by assessing measures of sub-clinical atherosclerosis and left ventricular mass and geometry.

Materials and methods

A total of 103 patients undergoing treatment for MetS were examined for confirmation of diagnosis, blood sampling, and measures of pulse wave velocity (PWV), carotid intima-media thickness (c-IMT), left ventricular mass index (LVM), and relative wall thickness (RWT). All subjects underwent a detailed dental assessment, including measurements of DMFT (decayed-missing-filled teeth) and periodontal parameters.

Results

Ten patients (10%) were diagnosed with healthy-mild periodontitis, 38 patients (37%) were diagnosed in the moderate periodontitis group, and 55 (53%) had severe periodontitis. A total of 37% of subjects were affected by dental caries. Linear regression analysis revealed that patients with severe PD had increased average ventricular RWT (adjusted p = 0.032). Average full mouth probing pocket depth (PPD) was also associated with RWT (adjusted p = 0.006). No associations between PD and c-IMT, PWV, and LVM were detected after adjusted analyses.

Conclusion

This study suggests that periodontitis may be associated with concentric left ventricular remodeling, a predictive index of cardiovascular events.

Clinical relevance

The presence of periodontitis in patients with MetS might have an effect on left ventricular geometry. These findings stress the importance of prevention, diagnosis, and management of periodontitis in patients with MetS.
