Cardio- and cerebrovascular responses to the energy drink Red Bull in young adults: a randomized cross-over study

• Red Bull consumption led to
• Increases in both systolic and diastolic blood pressure
• Increased heart rate and cardiac output
• no significant changes in total peripheral resistance
• Without diminished endothelial response to acetylcholine
• Myocardial load was increased
• Increases in cerebrovascular resistance and breathing frequency
• Decreases in cerebral blood flow velocity
• Pokles end-tidal carbon dioxide
• Overall negative hemodynamic profile in response to ingestion of the energy drink Red Bull
• Elevated blood pressure and double product
• Lower cerebral blood flow velocity
