Insights
Periodontal disease, including periodontitis and gingivitis, was not found to increase coronary heart disease (CHD) risk in individuals with pre-existing heart conditions. In fact, periodontitis showed a potential protective effect in those with prior heart attacks.
Area of Science:
- Cardiovascular Health
- Oral Medicine
- Epidemiology
Background:
- Periodontal infections are suspected to elevate the risk of future coronary heart disease (CHD) events in patients with existing heart disease.
- Understanding this potential link is crucial for managing cardiovascular health in at-risk populations.
Purpose of the Study:
- To investigate the association between periodontitis and subsequent CHD events.
- To analyze this relationship specifically within a cohort of adults who have pre-existing cardiovascular disease.
Main Methods:
- Utilized data from the First National Health and Nutrition Examination Survey Epidemiologic Follow-up Study.
- Followed a cohort of 636 dentate adults with pre-existing cardiovascular disease for CHD events.
- Assessed the presence of periodontitis and gingivitis and their correlation with CHD risk using hazard ratios (HR) and confidence intervals (CI).
Main Results:
- Periodontitis (HR, 0.97; 95% CI, 0.72-1.31) and gingivitis (HR, 1.09; 95% CI, 0.79-1.50) did not significantly increase CHD risk in the overall group of individuals with pre-existing cardiovascular disease.
- Among individuals who self-reported a prior heart attack, periodontitis was associated with a statistically significant decreased risk of CHD (HR, 0.66; 95% CI, 0.42-1.05).
Conclusions:
- Periodontitis and gingivitis do not appear to elevate CHD risk in individuals with self-reported pre-existing cardiovascular disease.
- Periodontitis may be associated with a reduced risk of CHD events in patients with a history of heart attack.
Abstract:
Periodontal infections in individuals with pre-existing heart disease are believed to increase the risk for future coronary heart disease (CHD) events. The goal of this study was to search for an association between periodontitis and CHD events among individuals with pre-existing heart disease, reported in the First National Health and Nutrition Examination Survey Epidemiologic Follow-up Study. Dentate adults (n = 636) with a history of pre-existing cardiovascular disease were followed for CHD events. The presence of periodontitis and gingivitis did not increase CHD risk among these at-risk individuals (hazard ratio [HR], 0.97, and 95% confidence interval [CI], 0.72-1.31; and HR, 1.09, and 95% CI, 0.79-1.50, respectively). When limited to individuals with a self-reported prior heart attack, periodontitis was associated with a 34% decreased CHD risk (HR, 0.66; 95% CI, 0.42-1.05). It is concluded that periodontitis or gingivitis does not elevate CHD risk among individuals with a prior heart attack or self-reported pre-existing cardiovascular disease.
