Medical News: AHA: Energy Drinks Amp Up Blood Pressure - in Meeting Coverage, AHA from MedPage Today:
"Energy drinks boost blood pressure in even the young and healthy people and may leave hypertensive adults more charged up than they bargained for, researchers said here. Consumption of two energy drinks a day increased systolic blood pressure by 10 mm Hg and heart rate by five to seven beats per minute, according to a small study reported at the American Heart Association meeting."
A very important point late in the article:
"...the main compounds implicated in the cardiovascular alterations -- caffeine and taurine -- are consistent ingredients across brands. This suggests the findings are likely generalizable across energy drinks, though not to sports drinks, which typically do not have caffeine, Dr. Kalus said."
This is an early study (in fact it is not yet published) but definitely an expected result.
