Abstract 11196: Dental Caries is Associated With Out-of hospital Cardiac Arrest of Cardiac Origin, but not Noncardiac Origin: From the All-Japan Utstein Registry
Background: Dental caries and periodontal disease are the two top problems in the oral cavity, and both contribute to the progression of atherosclerosis and coronary artery disease. However, there have been no reports on how they are related to out-of-hospital cardiac arrests (OHCAs). We hypothesized that dental caries might be associated with OHCAs of cardiac origin, but not non-cardiac origin.
Methods and Results: We compared the incidence of dental caries with OHCAs in the 47 prefectures of Japan. The estimated number of patients with dental caries (n=596,000) in each of the 47 prefectures was obtained from the Patient Survey of the Ministry of Health, Labour and Welfare of Japan. Patients who suffered from OHCAs of cardiac and noncardiac origin (n=365,622 and 293,209) and who were enrolled in the All-Japan Utstein Registry of the Fire and Disaster Management Agency between 2005 and 2010 were included. The age-adjusted incidence of dental caries was not correlated with OHCAs of total, cardiac or non-cardiac origin, and no relationship was observed with hypertension, diabetes mellitus or dyslipidemia. However, among male patients over 65 yrs of age, the incidence of dental caries was significantly associated with OHCAs of total (r=0.453, p=0.001) and cardiac origin (r=0.383, p=0.008), but not non-cardiac origin (r=0.220, p=0.137) (Figure).
Conclusion: While oral hygiene is important in all age groups, it may be particularly associated with OHCAs in males over 65 yrs of age.
