Abstract 15035: Fish Consumption is Associated with Out-of-Hospital Cardiac Arrest of Cardiac Origin, but not Noncardiac Origin: From All-Japan Utstein Registry Data
Background: Prospective cohort studies have shown that fish consumption is inversely related to fatal coronary heart disease, sudden cardiac death and stroke. We tested the hypothesis that fish consumption may be associated differently with out-of-hospital cardiac arrests (OHCAs) of cardiac and noncardiac origin.
Methods and Results: Adult 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 populations and consumption of fish and salt in 47 prefectures in Japan were obtained from data published by the Ministry of Health, Labour and Welfare of Japan. The patients who suffered from OHCAs of cardiac and noncardiac origin included 58.1% and 59.1% males, and were aged 75.2±14.2 y and 70.0±18.2 y, respectively. Fish consumption was significantly correlated with OHCAs of cardiac origin (r=0.48, P<0.001), but not noncardiac origin (r=0.18, P=0.22). In addition, among the different types of fish examined, the consumption of sardines showed a different correlation with OHCAs of cardiac origin than the consumption of saury and bonito (figure). On the other hand, salt consumption was more strongly associated with OHCAs of noncardiac origin (r=0.61, p<0.001) than with OHCAs of cardiac origin (r=0.28, P=0.06).
Conclusions: In Japan, the consumption of fish and salt showed different associations with OHCAs of cardiac and noncardiac origin, suggesting that dietary habits may play a role in out-of-hospital cardiac arrests.
