RESULTS	Unlike the water control load , Red Bull consumption led to increases in both systolic and diastolic blood pressure ( p < 0.005 ) , associated with increased heart rate and cardiac output ( p < 0.05 ) , with no significant changes in total peripheral resistance and without diminished endothelial response to acetylcholine ; consequently , double product ( reflecting myocardial load ) was increased ( p < 0.005 ) .\
