Carbonated drinks connected to cardiac arrest, study finds

DBR Staff Writer Published 02 September 2015

Consumption of soft drinks has been linked to cardiovascular disease (CVD) and stroke, while green tea and coffee have been found to minimize the risk and mortality, according to a study.

This was revealed in a study by All-Japan Utstein Registry that found such connection between out-of-hospital cardiac arrests of cardiac origin and carbonated beverages.

The study, which was conducted among around 800,000 patients, point to the fact that limiting such consumption might augur well for health.

Japan's Fukuoka University dean and professor Keijiro Saku, also the principal investigator, said: "Carbonated beverages, or sodas, have frequently been demonstrated to increase the risk of metabolic syndrome and CVD, such as subclinical cardiac remodeling and stroke. However, until now the association between drinking large amounts of carbonated beverages and fatal CVD, or out-of-hospital cardiac arrests (OHCA) of cardiac origin, was unclear."

"Carbonated beverage consumption was significantly and positively associated with OHCAs of cardiac origin in Japan, indicating that beverage habits may have an impact on fatal CVD... The acid in carbonated beverages might play an important role in this association."

The study made a comparison of the age-adjusted incidence of OHCAs with the consumption pattern of various beverages per person from 2005 to 2011 in the 47 prefectures of Japan.

In all, 797,422 patients having OHCAs of cardiac and non-cardiac origin from the All-Japan Utstein Registry of the Fire and Disaster Management Agency were also included in the study.

Ministry of Health, Labour and Welfare of Japan have provided the information on consumption of various beverages per person.

During analysis, it was revealed that 785,591 OHCA cases receiving resuscitation comprised 435,064 (55.4%) of cardiac origin and 350,527 (44.6%) of non-cardiac origin.

The non-cardiac origin covered cerebrovascular disease, respiratory disease, malignant tumour, and exogenous disease with percentages of 4.8, 6.1, 3.5 and 18.9, respectively.

It also came out during research that expenditure on carbonated beverages have a significant association with OHCAs of cardiac, but not non-cardiac origin.

Expenditures on other beverages, such as green tea, black tea, coffee, cocoa, fruit or vegetable juice, fermented milk beverage, milk and mineral water were also found to be not significantly associated with OHCAs of cardiac origin.

"Our data on carbonated beverage consumption is based on expenditure and the association with OHCA is not causal. But the findings do indicate that limiting consumption of carbonated beverages could be beneficial for health," Professor Saku added.
