Can you believe that energy drinks can affect the heartbeats of even healthy adults, hours after consumption? A recent study has proven this fact. According to a research report presented at the annual meeting of the Radiological Society of North America in Chicago, consuming energy drinks containing caffeine and taurine may alter heart function in healthy adults.
18 healthy volunteers including 15 men and 3 women with mean age of 27.5 years were investigated for the research purpose. The German researchers used magnetic resonance imaging (MRI) to measure the heart function of 18 healthy participants both before and one hour after they consumed an energy drink. The beverage used in the study contained both taurine (400 mg/100 ml) and caffeine (32 mg/100 ml).
Each participant underwent an MRI before and one hour after consuming an energy drink containing taurine and caffeine. Magnetic resonance imaging (MRI) is a type of scan that uses strong magnetic fields and radio waves to produce detailed images of the internal body parts. Researchers as well as healthcare centers are using this innovative diagnostic modality. A cardiac MRI uses radio waves, magnets and a computer to create pictures of the heart to look at its structure and function.
Researchers measured heart contractions before and after volunteers consumed a single energy drink. They found that energy drinks are creating additional strain on the organ and causing it to contract more rapidly than usual.
After consuming energy drinks, the participants experienced a significant increase in contractions in the heart’s left ventricle, which is responsible for receiving oxygen-rich blood from the lungs and pumping it into the aorta, which distributes the blood throughout the body.
Researchers concluded that although the study confirms that energy drinks have a short-term impact on heart function, further studies are needed to evaluate the long-term effects of consuming energy drinks and the effect energy drinks have on patients with heart disease.
