Cardiac MRI Shows Disruption of Normal Heart Function with Consumption of Energy Drinks

Previous studies have shown the dangers of energy drinks to cardiovascular health. Yet a recent study zeros in on the dramatic problems associated with heart rhythm that heavy consumption of these beverages can create.
"Until now, we haven't known exactly what effect these energy drinks have on the function of the heart," researcher Jonas Dörner, said via a press release. "There are concerns about the products' potential adverse side effects on heart function, especially in adolescents and young adults, but there is little or no regulation of energy drink sales."
The study looked at 18 healthy individuals, all around the age of 28. Participants took energy drinks with 400 mg taurine and 32 mg caffeine per 100 mi. Cardiac magnetic resonance imaging (MRI) helped to monitor the function of each individual's heart, both before and after drinking the energy beverage.
As most energy drinks carry high levels of various chemicals, primarily consisting of taurine and caffeine, researchers believe this may explain the hidden risk often involved with their consumption.
"Usually energy drinks contain taurine and caffeine as their main pharmacological ingredients. The amount of caffeine is up to three times higher than in other caffeinated beverages like coffee or cola," Dörner stressed, via the release. There are many side effects known to be associated with a high intake of caffeine, including rapid heart rate, palpitations, rise in blood pressure and, in the most severe cases, seizures or sudden death."
The findings were presented at the annual meeting of the Radiological Society of North America (RSNA), held in Chicago today.
