Insights
Periodontopathic bacteria like Aggregatibacter actinomycetemcomitans may increase hypertension risk in men. This study found higher bacterial detection in male cardiovascular patients with hypertension.
Area of Science:
- Cardiovascular Health
- Oral Microbiology
- Systemic Disease Etiology
Background:
- Hypertension (HT) significantly impacts quality of life and mortality.
- Periodontitis is a known risk factor for HT, but causal links remain unclear.
Purpose of the Study:
- To investigate the association between periodontopathic bacterial infections and hypertension in cardiovascular patients.
- To identify specific bacterial species potentially linked to hypertension development.
Main Methods:
- Evaluated three periodontopathic bacteria and their antibody titers in cardiovascular patients with (n=412) and without (n=199) HT.
- Conducted blood examinations and periodontal measurements.
- Assessed rates of obesity, dyslipidemia, and diabetes.
Main Results:
- Aggregatibacter actinomycetemcomitans and Prevotella intermedia were more prevalent in male patients with HT.
- No significant difference in these bacteria was observed between female patients with and without HT.
- Elderly male patients with HT exhibited greater mean probing pocket depth.
Conclusions:
- Specific periodontopathic bacterial infections may contribute to hypertension in male cardiovascular patients.
- The findings suggest a potential gender-specific role of oral bacteria in hypertension etiology.
Abstract:
Hypertension (HT) is a systemic disorder that results in the decline of quality of life and death. While patients with periodontitis are at a high risk of HT, little causal information has been provided to date. To clarify the relationship, periodontopathic bacterial infection in cardiovascular patients with or without HT was evaluated. The subjects were patients with (n = 412) or without (n = 199) HT who attended Tokyo Medical and Dental University hospital. Blood examinations and periodontal measurements were performed. Three periodontopathic bacteria existence and antibody titers were evaluated. We found that specific periodontopathic bacteria, Aggregatibacter actinomycetemcomitans and Prevotella intermedia, were highly detected in male subjects with HT compared to non-HT subjects, while they were comparable in the female patients. Mean probing pocket depth of elderly male patients with HT was higher compared to non-HT patients. The rates of obesity, dyslipidemia, and diabetes showed partial statistical difference between the two groups. Specific periodontopathic bacterial infection may affect HT in male cardiovascular patients.
