Energy drinks may help improve heart function

Washington: Energy drinks can exert acute positive benefits on heart performance, a new study has revealed.

The current study, led by Dr Matteo Cameli from University of Siena, which used avant-garde technique in echocardiography and echo Doppler analysis to explore the influence of energy drinks on heart function on 35 healthy subjects, found that their ventricular functions were better and enhanced.

The participants were given an energy drink (168 ml/m2) containing caffeine and taurine.

When their heart rate, blood pressure, left ventricular function and right ventricular function were analysed one hour after consumption, they were found to be relatively deviated from baseline values.

Although the increase in heart rate, systolic blood pressure and diastolic blood pressure were not significantly changed, left ventricular function improved in comparison to baseline.

The functioning of right ventricle also improved one hour after consuming energy drinks.

"Taken together these results show that energy drinks enhance contractions of both the left and right ventricles, thereby delivering a positive effect on myocardial function," Dr Cameli said.

"This could be explained by the inotropic effect of taurine that, as previously demonstrated, stimulates the release of calcium from the sarcoplasmic reticulum,” he added.
