ENERGY drinks can lead to heart problems and ‘sudden death’, according to startling new revelations at a Barcelona medics’ conference.

Professor Milou-Daniel Drici told the European Society of Cardiology Congress that the high caffeine content in the popular fizzy drinks can lead to angina, cardiac arrhythmia (irregular heartbeat) and can even be fatal.

Drici warned against the general public’s attitude and awareness of the drinks, saying that more information needed to be provided.

“The general public need to know that so-called ‘energy drinks’ have absolutely no place during or after physical exercise, as compared with other drinks designed for that purpose,” he said.

“When used in long alcoholic cocktails, the caffeine in ‘energy drinks’ enables young people in dance clubs or elsewhere to overcome the unwanted effects of alcohol, leading to an even greater intake of caffeine.”
