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

Med J Aust. 2009 Jan 5;190(1):41-3. doi: 10.5694/j.1326-5377.2009.tb02263.x.


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.
