Abstract

Background. The objective of this study was to investigate the prevalence of periodontitis in patients with chronic heart failure, as well as to characterize the microbiological profile of periodontitis across different chronic heart failure phenotypes. The objective is to analyze the link between oral health and heart disease.

Materials and Methods. A cohort of 98 chronic heart failure patients (mean age 62.22 ± 8.62 years, 69 men) was assessed through comprehensive cardiological and periodontal examinations. Patients were categorized into heart failure with reduced ejection fraction, mildly reduced ejection fraction, and preserved ejection fraction. Periodontal parameters, including probing pocket depth, clinical attachment loss, and bleeding on probing were evaluated. Microbiological and statistical analyses were conducted.

Results. Severe periodontitis (Stage C) was identified in 30% of patients, while 48% had moderate periodontitis (Stage B). Patients with chronic heart failure with reduced ejection fraction exhibited the highest prevalence of severe periodontitis, with a significant correlation between increased probing pocket depth and reduced ejection fraction. Candida species abundance was associated with lower ejection fraction (p≤0.0Y) and advanced periodontitis (p≤0.0X). Elevated NT-proBNP levels (1121.00–7611.00 pg/mL) correlated with Streptococcus mitis prevalence, while C-reactive protein levels (up to 2.35 mg/dL) were highest in patients with Klebsiella pneumoniae.

Conclusion. The study highlights a strong association between periodontal disease, microbial dysbiosis, and CHF. Findings suggest that oral microbial imbalances, particularly involving Candida, Streptococcus mitis, and Klebsiella pneumoniae, contribute to systemic inflammation and cardiovascular complications.
