Cardiac arrest in a young man following excess consumption of caffeinated “energy drinks”

Adam J Berger and Kevin Alford
Med J Aust 2009; 190 (1): 41-43.

An otherwise healthy 28-year-old man had a cardiac arrest after a day of motocross racing. He had consumed excessive amounts of a caffeinated “energy drink” throughout the day. We postulate that a combination of excessive ingestion of caffeine- and taurine-containing energy drinks and strenuous physical activity can produce myocardial ischaemia by inducing coronary vasospasm.

A 28-year-old male amateur motocross rider was admitted to Port Macquarie Base Hospital in August 2007 after having an out-of-hospital cardiac arrest. He had collapsed shortly after participating in a motocross race. An off-duty paramedic and nurse had been on hand, and effective cardiopulmonary resuscitation was commenced promptly. Paramedics arrived after about 20 minutes of resuscitation.
