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.
含咖啡因饮料在全球范围内广受欢迎，这主要是因为它们对人体生理有刺激作用。然而，短期和长期的结果研究表明，它们对整体健康的影响各不相同。在这项初步研究中，我们让一组 23 名健康个体摄入 240 毫克咖啡因，形式为咖啡或能量饮料，并进行重复脉搏波分析。这种实验方法是为了根据咖啡因摄入形式，研究咖啡因摄入对血管张力的急性影响。我们的数据表明，与咖啡相比，能量饮料可能会对收缩压和脉搏波速度产生负面影响。鉴于观察到的影响与持续暴露时心血管事件风险增加有关，因此在心血管健康方面需要特别注意这个问题。
