Only one energy drink can affect blood vessel functions and may raise the risk of heart attack, says a new study to be released at the 2018 American Heart Association (AHA) scientific panels in Chicago.
Scientists at the UTHealth McGovern School of Medicine in Houston surveyed 44 healthy, non-smoking, 20-year-old students of medicine for a small-scale study focused on energy drinks and their effects on the organism.
Each of the students consumed a 700-milliliter energy drink, while the researchers examined its effect on blood vessels up to 90 minutes after consumption. They compared the results with the outcomes of the examinations taken about one hour and a half before the consumption of the energy drink.
The scientists employed ultrasound screening to estimate the blood vessel dilation caused by the arterial flow which indicates the quality of the blood vessels.
One Energy Drink Is Enough To Raise The Risk Of Heart Attack
In their study, the researchers discovered that blood vessel dilation averaged to 5.1 percent before consuming the energy drink and plummeted to 2.8 percent afterward, hinting to a severe deterioration in the circulatory function.
These findings demonstrate that energy drinks can decrease blood flow to vital organs in the body while at the same time raising the risk of heart attack and other conditions due to the constriction of blood vessels.
John Higgins, M.D., and his co-workers who participated in this research described this outcome as possibly triggered by the combined effect of the substances found in energy drinks, many of which contain significant quantities of caffeine, taurine, herbal ingredients (Guarana, Ginseng), and sugars.
“As energy drinks become increasingly popular, it’s important to study the effects of these drinks in those who consume them frequently and to better determine which, if any, is the safe drinking pattern,” the researchers concluded.
