Energy Drinks Linked To Increased Heart Disease Risk
ByNew research suggests that drinking one energy drink could cause changes that could conceivably trigger new cardiovascular events, Live Science reported.
Researchers found that one 16-ounce energy drink boosts blood pressure and stress hormone responses in young, healthy adults which could boost disease risk.
"The worry is that if these responses are seen in healthy young people, perhaps the effects of energy drinks may be more pronounced in people who already have high blood pressure or arrhythmias," lead researcher Dr. Anna Svatikova told Health Day.
This could lead to more heart attacks and strokes.
For the study, researchers collected and analyzed data from 25 healthy young adults with no known cardiovascular risk factors.
Each drank one 16-ounce can of a commercially available energy drink or a sham drink in random order on two separate days. Researchers measured participants' blood pressure and blood levels of norepinephrine before and 30 minutes after drink consumption. Norepinephrine is a "fight or flight" chemical that increases blood pressure and the heart's ability to contract and it modulates heart rate and breathing in response to perceived stress.
They found that in addition to increases in blood pressure after consuming the energy drink, participants' norepinephrine levels increased more than twice as much when compared to those who drank the sham drink. Specifically, norepinephrine levels increased by almost 74 percent after the energy drink consumption, versus by 30 percent after the sham drink.
Based on the findings, researchers concluded that increases in blood pressure and stress hormones could predispose otherwise healthy, young adults to increased cardiovascular risk.
The findings were presented at the American Heart Association's Scientific Sessions 2015.
