Background: Many studies on the cardiovascular complications linked to energy
drinks consumption imply that their effect on endothelial function might be a causal
factor in subsequent cardiac events.
Aim: This research investigated whether energy drinks consumption could cause
acute endothelial function impairment as surrogated by flow-mediated dilation in
healthy young adults.
Subjects and methods: This observational study was done in Benha University
Hospital in the period from July 2021 to June 2022, and included 50 healthy young
adults for analyzing the normal endothelial function before and after consuming a
single popular energy drink (ED) can, to assess its effect on endothelial function.
All subjects underwent full history taking, clinical examination, Electrocardiogram,
and flow-mediated vasodilation (FMD) measurements.
