Key result
Energy drinks, in contrast to coffee, might negatively impact systolic blood pressure and pulse wave velocity in healthy individuals.
Why the study?
Studies on short- and long-term health outcomes of caffeinated beverages have shown variable results, prompting investigation into acute effects on vascular tone depending on the form of caffeine intake.
Does 240 mg of caffeine from energy drinks compared to coffee negatively impact vascular tone in healthy individuals?
Does 240 mg of caffeine from energy drinks compared to coffee negatively impact vascular tone in healthy individuals?
Energy drinks may have a more negative acute impact on vascular tone (systolic blood pressure and pulse wave velocity) compared to coffee in healthy individuals.
May warrant caution with energy drinks for vascular effects; leaves open confirmation versus coffee in larger trials.
Caffeinated beverages are popular throughout the world, especially due to their stimulating effects on body physiology. However, short- and long-term outcome studies have shown variable results on general health. In this pilot study, we exposed a cohort of 23 healthy individuals to 240 mg of caffeine either in the form of coffee or energy drinks and performed repetitive pulse wave analyses. This experimental approach was chosen to investigate the acute effects of caffeine consumption on vascular tone depending on the form of caffeine intake. Our data indicate that energy drinks, in contrast to coffee, might negatively impact systolic blood pressure and pulse wave velocity. This issue needs special attention in the light of cardiovascular health as the observed effects have been associated with an increased risk of cardiovascular events upon persistent exposure.
