01 April 2015 - ScienceDaily - Dangers of adolescent energy drink consumption for the heart: Cardiologists urge physicians, parents, educators to monitor adolescents' energy drink consumption more closely

The rapid rise in popularity of energy drinks (EDs), particularly among adolescents (aged 10-19 years) and young adults, has serious implications for cardiac health, scientists say.

In an article published in the Canadian Journal of Cardiology, researchers focus on the pharmacology of EDs, adverse reactions to them, and how the marketing of these drinks as a means to relieve fatigue and improve physical and cognitive performance may be ignoring real dangers.

An international research team noted that EDs can trigger sudden cardiac deaths in young, apparently healthy individuals. For persons with underlying heart diseases, the risk of triggering sudden arrhythmic death syndrome (SADS) or other arrhythmias can be significant. Even atrial fibrillation (AF), normally uncommon in children without structural heart disease, has been observed in a 13-year-old adolescent boy during a soccer training session after ingesting EDs.

It is estimated that 31% of 12- to 19-year old adolescents regularly consume EDs. These beverages often contain high amounts of labeled caffeine. However, they can contain "masked" caffeine, in the form of guarana, for example, which comes from a Brazilian plant and is identical to caffeine found in coffee beans, but at twice the concentration. The addition of guarana and other substances such as ginseng and taurine in variable quantities may generate uncertain interactions.
