A Randomized Trial of Cardiovascular Responses to Energy Drink Consumption in Healthy Adults
This
randomized clinical trial of young healthy volunteers assessed the
association between energy drink consumption and cardiovascular
responses.
Energy drink consumption has been associated with serious cardiovascular events,1- 4
possibly related to caffeine and other stimulants. We hypothesized that
drinking a commercially available energy drink compared with a placebo
drink increases blood pressure and heart rate in healthy adults at rest
and in response to mental and physical stress (primary outcomes).
Furthermore, we hypothesized that these hemodynamic changes are
associated with sympathetic activation, which could predispose to
increased cardiovascular risk (secondary outcomes).
